Jar Test Results

Moss Landing Desalination Pilot Plant

Jar test experiments

Date: 04/17/08

Jar test experiments were performed in Moss Landing Pilot plant lab. The results presented in this report correspond to MWH experiments proposed in table 2-2 from the Appendix E of the Test plan draft. In Table 1 the sampling information is presented. The analysis results are in Table 2. I would like to point out that the turbidity for the all the samples was measured with two turbidimeters, the one we have on site and another one from CalAm lab. The reason is that we are trying to get new standard calibrating solutions for the on site instrument because we think the readings are not accurate. Pictures from all jar test performed are presented in Figures 1-46.

To: David Berger John Klein Anthony Cappa From: Orren Schneider Re: Results from Moss Landing Jar Tests Summer 2009 As part of our Water Research Foundation Tailored Collaboration Project (Project Number #4280; Novel Methodologies for Evaluation of Fouling Reduction of Desalination Membranes), I conducted a series of jar tests using water from the Moss Landing Pilot Plant to examine impacts of coagulation of organic and particulate removal. The goal of the project is to use several new methods to improve removal of foulants from the water to aid in RO performance. These methods include the use of a zeta potential instrument and the use of an American Water developed AOC method. Both methods are suitable for use in marine/high salinity environments. For these tests, dissolved is defined as material passing through a 0.22 µm silver membrane. I had also tried using ultrafilters with a 3,000 Dalton molecular weight cut-off but was not able to wash surfactant material off of the membrane reliably. These data are not included here. Prior to starting these tests, I consulted with a number of membrane “experts” from several consulting firms (MWH, CH2M Hill, Black and Veatch) about the use of polymers with membranes. The general consensus was that polymer could be used with low pressure membranes, but that their use should be limited to low doses. Certain types should be avoided altogether. Based on this knowledge, I chose two cationic polymers to test. I had agreed with the Project Advisory Committee from the Foundation project that should a polymer be recommended for pilot testing, that I would run some tests using RO membrane material to ensure that irreversible fouling or membrane poisoning did not occur. The fact that low doses (<1 mg/L), low pressure membranes, and cartridge filters exist would also help to minimize any free polymer that could reach the RO membranes. Anthony Cappa sent me 10 gallons of water at the end of June. I ran about 8-9 jar tests using a variety of coagulants. I needed to repeat several tests due to problems with our TOC analyzer. The mixing times and energies I used were based on information from Karla Kinser and Anna using values from Run 1. I translated those mixing energies (G-values) to appropriate mixing speeds for 500 ml water in a 1-liter round beaker. I was able to get results from six tests which I will summarize below.

1. Ferric Chloride In general, there was little organic matter or turbidity removal seen for ferric doses between 2 and 10 mg/L. There may be a slight optimum point at 4 mg/L based on AOC removal and a minimum in dissolved iron. The fact that the TOC and DOC are so similar indicates that the dissolved organic fraction is smaller than 0.22 µm. The ferric doses used are not enough to create adsorption sites for these organics.

2. Ferric Chloride @ pH 6.5 For this test, the pH of raw water was adjusted to pH 6.5±0.1 using 0.1N H2SO4. Water dosed with 10 mg/L ferric chloride was also adjusted to pH 6.5±0.1. Both values were recorded. Prior to the actual jar test, appropriate doses of 0.1 N sulfuric acid were added to each of the six jars. For doses between 2 and 10 mg/L, the acid doses were interpolated. During the jar test, the pH in each jar was pH 6.5±0.15; after settling, the pH of the water in each of the jars increased due to contact with the atmosphere. The results of the tests showed an optimum coagulation point at between 4-6 mg/L of ferric chloride.

3. Polyferric sulfate Polyferric sulfate (PFS) is the iron analog of polyaluminum chloride. While it is a polymer, it is inorganic in nature and contains no “traditional” polymers (polyacrylamide, poly(DADMAC), etc.). The tests were conducted at ambient pH. The results show little organic or turbidity removal at doses between 0 and 10 mg/L.

6. Ferric Chloride and 587C In order to evaluate possible synergy between ferric and the cationic polymer, a jar test using both was conducted. Based on both the economic and membrane protection factors, the chosen polymer dose was 0.4 mg/L, slightly below the optimum chosen based on the jar test with the 587C alone. The results of the jars showed results similar to the ferric chloride alone; some impact was seen on turbidity removal at 8 mg/L of ferric. Little impact was seen on TOC or DOC removal. AOC removal was maximized at a ferric dose of 6 mg/L.

Zeta Potential (mV)

Other measurements In addition to the conventional jar test measure, I also measured the zeta potential distribution in raw water, coagulated waters, and settled water. These data are somewhat incomplete due to the difficulty in measuring zeta potential in high ionic strength waters. This monitor measures the zeta potential (surface charge) of all particles between 3 nm and 3 µm. A number of interesting results were gathered from these measurements. I will illustrate them with several graphs. a. The zeta potential distribution in the sea water is much greater than in fresh water. In this graph, the zeta potential distribution of Moss Landing raw water is in red, while the green line shows the zeta potential distribution of a surface water in NJ. The most interesting items from this graph are that stable particles exist in the seawater between -5 and +5 mV. In traditional colloid theory, particles with surface charges between -5 to + 5 mV should coagulate rapidly, apparently they do not in the seawater (notice that there are no particles with positive charges in the surface water). b. Mixing alone has an impact on particle interactions

Zeta Potential (mV)

In this graph, the zeta potential distribution of Moss Landing raw water is in red, while the green line shows the zeta potential distribution of settled water with no coagulants added, but that had been rapid mixed, slow mixed, and settled according to the jar test procedure. It is interesting to note that the high charge particles (both positive and negative) had been reduced. This may indicate that the mixing brought the particles together and allowed them to agglomerate and then settle out. The fact that neutral particles exist in the raw water combined with the fact that despite plenty of mixing in the open ocean would suggest that a stabilizing factor, likely due to adsorbed organic matter, prevents particles from coagulating naturally. c. Coagulants have an impact on zeta potential

In this graph, the zeta potential distribution of raw water is shown in red; the green line shows the zeta potential distribution of settled water with no ferric chloride and 0.4 mg/L of 587C added; the blue line shows the zeta potential distribution of settled water with 10 mg/L of ferric chloride and 0.4 mg/L of 587C. The presence of the polymer alone reduced the high charge shoulders. The addition of ferric chloride increased this effect.

Preliminary Conclusions

The results of the jar testing suggest a number of items

Zeta Potential (mV)

1. Organic matter, including assimilable organic carbon can be successfully coagulated. Removal is dependent on coagulant type, dose, and pH. Organic removal by ferric chloride alone is minimal. Removal with relatively low doses of poly(DADMAC) polymer were optimal.

2. Turbidity removal is highly dependent on the proper coagulant and proper coagulant dose. Most of the settled particles when using ferric chloride appear to be due to the coagulant addition, not particle pre-existing in the seawater.

3. Mixing alone appears to aid in removal of particles, likely due to the mixing energy overcoming steric barriers caused by adsorbed organic matter

The results of pilot test Run #1 appeared to indicate that the Siemens membrane fouled rapidly with 5 mg/L of ferric chloride added. However, the RO membrane, fed exclusively with water from the Siemens membrane had the longest run of any of the existing five runs. This may indicate that the ferric transferred the fouling from the RO membrane to the ultrafiltration membrane. Based on this, I would suggest operating the Siemens membrane with 5-6 mg/L of ferric chloride, but at a lower flux than during Run #1 may improve performance of the RO membranes. I would also suggest examining the use of a poly(DADMAC) polymer, but given the time limitations of the pilot testing understand that this is probably not a realistic option at this point.

American Water provided two Toray TM820C-400 sea water reverse osmosis

elements to Avista Technologies for autopsy. Element serial numbers (SN#) were

80441249 and 80441256, removed from the lead (#1) and tail positions (#7),

respectively. Elements were wet tested on San Marcos, CA tap water and data

was normalized to seawater conditions. Elements were weighed and dissected

for autopsy. Please refer to the element drawing in Appendix A, Figure 1 for an

explanation of terms used throughout this report.

Both elements showed high permeate flow and low salt rejection on initial pre-

test. SN# 80441249 flat sheet cut membrane samples mimicked full element wet

test. There was no evidence of mechanical failure (i.e. glue line failure or

delamination).

Exposed membrane surfaces for SN# 80441249 were only lightly coated with a

very thin layer of colorless gelatinous foulant (See photos of exposed membrane

surfaces in Appendix B, Figures 1 and 2). Insufficient foulant was present on SN#

80441249 to perform LOI and foulant density tests. Light microscope analysis of

the gelatinous foulant from SN# 80441249 showed amorphous organic material

and few Gram positive cocci bacteria (See photo in Appendix B, Figure 3). Vexar

feed spacer in both elements was free of foulant. SN# 80441256 contained

insufficient foulant that could be sampled to perform LOI, foulant density, or light

microscope analysis.

SEM/EDX analysis of both elements identified only trace amounts of clay as

inorganic foulant. However, it must be noted that very little inorganic foulant was

present on either membrane surface (See SEM images in Appendix B, Figures 4

and 5). FT-IR analysis identified polysaccharides, proteins, and sugars on both

membrane surfaces (See IR spectra in Appendix B, Figure 6). Flat sheet

membrane coupons were cleaned with RoClean P303 followed by RoClean

P111 at standard dilution (2% by weight) and heated to 40°C for 2 hours each.

Post clean cell test data shows increased water and salt passage after cleaning.

It is likely that organic surface foulant was masking damaged membrane

surfaces.

Fujiwara testing was positive for the presence of halogen (i.e. chlorine) on both

autopsied elements. High salt passage of membrane coupons before and after

cleaning is caused by halogenation of the membrane surface (probably due to

chlorine exposure). Feed water dechlorination equipment and procedures

should be reviewed to assure complete removal of total chlorine prior to the RO

elements.

Supporting data is included in the Procedures and Results, or Foulant Analysis

section of this report.

ELEMENT WEIGHT

Because element weight is often indicative of the degree of fouling, elements

are weighed prior to the autopsy. SN# 80441249 and 80441256 weighed 36 and

34 pounds, respectively. New elements of this model weigh approximately 32-35

pounds.

EXTERNAL INSPECTION

Fiberglass wrap:

The outer fiberglass casing of both elements was in satisfactory condition.

Telescoping of element leaves:

Both ends of the element were examined for signs of membrane and feed

spacer extrusion. This type of damage is termed "telescoping" and is caused by

the development of high differential pressure (usually greater than 12 psi) across

the element. No telescoping was observed on either element.

Brine seals:

Brine seals were in good condition and showed no signs of damage that could

allow bypass of the RO concentrate water around the spiral wound membrane

scroll.

Anti-telescoping devices (ATD):

The ATD’s are designed to prevent telescoping of element leaves at normal

differential pressures. ATD’s on both elements were in good condition and

showed no sign of physical damage.

Permeate tubes:

No gouges were visible on the ends of the permeate tubes that could allow the

by-pass of feed water.

INTERNAL EXAMINATION

Membrane Surface:

Exposed membrane surface for SN# 80441249 contained a uniformly distributed

colorless gelatinous foulant (See Photo in Appendix B, Figure 1). Exposed

membrane surface for SN# 80441256 was essentially free of visible foulant

(Appendix B, Figure 2).

Fujiwara test:

The Fujiwara test is used to confirm that a polyamide (PA) thin-film membrane

has been exposed to an oxidizing halogen, such as chlorine, bromine, or iodine.

The test analyzes qualitatively whether halogens have become part of the

polymer structure through oxidative attack.

The Fujiwara test was positive on samples from both elements.

Feed spacer:

The feed spacer is a plastic net material (Vexar) designed to separate

membrane leaves to form a flow pathway and to promote turbulence within

feed water passages. Feed spacer in both elements was completely free of

foulant.

Permeate spacer:

Permeate spacer (Tricot) provides a pathway for permeate flow to central

permeate tube which minimizes permeate-side pressure loss. Tricot material was

in good condition in both elements.

Glue lines:

Membrane leaves are glued on three sides to separate feed and permeate

streams. Glue lines in both elements were in good condition and showed no

signs of pouching or delamination.

CELL TEST & LABORATORY CLEAN-IN-PLACE STUDY

Membrane samples were tested in a cell-test apparatus to determine

membrane performance characteristics. The permeate flow constant is

expressed as the “A” value, and the salt passage constant is expressed by a “B”

value. Both constants are functions of the chemical-physical properties of the

membrane plus any fouling layer present.

“A” and “B” value constants are also independent of operating parameters such

as pressure, temperature, and salt content of the feed stream. “A” value units

are cm/sec/atm. “B” value units are cm/sec. The table below shows

performance data before and after cleaning.

Loss on ignition:

Loss on ignition gives an approximation of the organic content of the foulant.

Values in excess of about 35% represent a significant organic content.

Insufficient foulant was present on either element to perform this test.

Membrane foulant density:

Membrane foulant density is the weight of dry foulant per area of membrane

surface. Foulant densities determined from past autopsies range from 0.04 to 1.6

mg/cm2 and average 0.203 mg/cm2. Insufficient foulant was present on either

element to perform this test.

Acid test:

Several drops of dilute hydrochloric acid were placed on the foulant surfaces.

Bubbles indicate the presence of carbonates. No bubbles were seen on the

membrane surface for either element.

Microbiological examination:

Foulant samples were stained and examined with a light microscope. Gram

positive bacteria are stained blue while Gram negative bacteria are stained red.

Gram positive and Gram negative bacteria were both observed during

microscope analysis for SN# 80441249 (See photo in Appendix B, Figure 3).

Insufficient foulant was present on the membrane surface of SN# 80441256 to

perform a microbiological examination.

Fourier Transformed Infrared (FT-IR) analysis:

FT-IR analysis identifies organic foulant constituents. FT-IR is a measurement

technique whereby spectra are collected based on measurements of temporal

coherence of a radiative source, using time-domain measurements of

electromagnetic radiation. Spectra are compared against a library of more than

10,000 known constituents.

FT-IR spectrum of foulant from SN# 80441249 shows the presence of organic

foulant; polysaccharides, proteins, and sugars FT-IR spectrum of foulant from SN#

80441256 indicates limited amounts of organic material.

ZETA POTENTIAL:

Most naturally occurring colloids are negatively charged and surrounded by a

double layer of counter ions, Figure 1. Zeta potential is the charge that resides at

the double layer boundary, which we can conveniently measure with a zeta

potential meter.

Electrostatic repulsion becomes significant when two colloids approach each

other and their charged double layers begin to interfere. Because of this mutual

repulsion, coagulation and flocculation are difficult to accomplish and

coagulants are often overfed into the RO system resulting in a positive zeta

potential. Samples that show a near zero or neutral zeta potential represent the

optimum coagulant dosage.

2 grams of wet foulant was suspended in 200 mL of deionized H2O + 10 ppm

NaCl. Zeta potential of foulant from SN# 80441249 was -20.5 mV indicating there

was no coagulant overfeed in the system, or none used at all. Insufficient foulant

was present in SN# 80441256 to perform this test. Foulant solution pH was 7.2.

Scanning Electron Microscopy /Energy Dispersive X-ray Analysis (SEM/EDX):

EDX analysis is conducted in conjunction with SEM imaging to identify inorganic

foulant constituents. In this technique, an electron microscope with an energy

dispersive X-ray spectrometer is used for analysis. Electron beams in the

microscope cause specimens to emit x-rays including those from the k, l and m

atomic shells. Spectrometer counts of these x-rays, which are said to be

“characteristic” of elements present in the specimen, can be used to calculate

composition of foulant material. This analysis is non-destructive and is accurate to

~1%. The elements Ca, Fe, Al, and SiO2 were present on the surface of both

elements indicating the presence of clay or silt (Appendix B, Figure 6). Insufficient

foulant could be removed from SN# 80441256, therefore a membrane sample

was analyzed (Appendix B, Figure 7). Elevated sulfur value is due to interference

from the polysulfone layer. All inorganic constituents are listed in the table below.

Detection of C and O along with trace phosphorous is related to the presence of

organic matter.

ESCA Analysis Results

X-ray Photo-electron spectroscopy (XPS), also known as Electron Spectroscopy for

Chemical Analysis (ESCA), is a surface analysis technique used for obtaining chemical

information from the surfaces (~50-60 angstroms) of solid materials. The method utilizes

an X-ray beam to excite a solid sample resulting in emission of photo-electrons. An

energy analysis of these photoelectrons provides elemental as well as their chemical

bonding information on the surfaces. Precise determination of binding energies is made

through the use of curve-fitting routines. A database is available for identifying binding

energies with actual compounds.

A membrane sample from Serial Number 80441249 was analyzed to determine the

cause for membrane surface damage. Results are shown in the table below.

ESCA RESULTS

Serial Number SN# 80441249

Chlorine, % 0.15

Bromine, % ND

Oxidation Yes

pH hydrolysis No

ND= Not detected

The Fujiwara test result from the membrane autopsy report is positive and chlorine was

found during ESCA analysis. Membrane surface damage is likely due to chlorine

exposure. The membrane sample also showed signs of oxidative damage that could be

associated with peroxide/peracetic acid exposure. If peroxide based products were

never used then the oxidation damage is likely halogen related.

California American Water provided two Toray TMG10 reverse osmosis elements

to Avista Technologies for autopsy. Element serial numbers (SN#) were 70631256

and 70631299; and positioning within the system was 2nd Pass Feed and 2nd Pass

Tail, respectively. Elements were wet tested on San Marcos, CA tap water and

data normalized to manufacturer’s standard test conditions. Elements were then

weighed and dissected for autopsy. Please refer to the element drawing in

Appendix A, Figure 1 for an explanation of terms used throughout this report.

Both elements showed lower than normal permeate flow and reduced salt

rejection on baseline wet testing. Flat sheet cut membrane samples from each

individual element both showed salt rejection and permeate flow with normal

manufacturer’s specification during laboratory wet testing. There was no

evidence of mechanical failure (i.e. glue line failure or delamination) in either

element.

Exposed membrane surfaces for both elements were essentially free of any

visible foulant material. Insufficient foulant material was able to be collected

from either element to perform density analysis, loss on ignition (LOI) for organic

content, zeta potential, and light microscope analysis.

FT-IR analysis identified polysaccharides, proteins, and carbohydrates in foulant

from both elements (See IR spectra in Appendix B, Figure 3). SEM/EDX analysis of

SN# 70631256 identified silica scale along with trace amounts of iron-rich clay as

inorganic foulant material. For this particular foulant material, RoClean P303 and

P111 solutions are recommended at standard dilution (2% by weight in RO/DI

water) and heated to 40-45 ˚C for 2 hours before rinsing. Rinsing should occur

between subsequent treatments of P303 followed by P111.

SEM/EDX analysis of SN# 70631299 identified silica scale along with trace

amounts of iron-rich clay as inorganic foulant material and therefore should be

cleaned with the combination of RoClean P303 followed by P112 in the fashion

mentioned above. SEM images of both elements’ foulant material are in

Appendix B, Figures 4 and 5.

Fujiwara test was positive on samples from both elements for the presence of

halogen (i.e. chlorine). High salt passage after cleaning is likely due to

halogenation of the rejecting membrane surface. RO system dechlorination

equipment and procedures should be reviewed to assure that zero total chlorine

is allowed to the membrane.

Supporting data is included in the Procedures and Results, or Foulant Analysis

sections of this report.

MWH – Moss Landing provided a Memcor module to Avista Technologies for

dissection and analysis. Dissected fibers were removed for sampling from the

Memcor module and were analyzed using SEM/EDX & FT-IR to characterize the

surface foulant. Module serial number (SN#) was 119105.

The module was creased near the center, but otherwise was free of any obvious

defects. The UF fibers appeared visually clean, so a sample from the center

section of the bundle was chosen for analysis (See photos in Appendix A, Figure

1).

SEM/EDX analysis identified iron aluminum silicate clay as the primary inorganic

foulant (See SEM image in Appendix A, Figure 2). Some iron and aluminum oxides

may also be present. FT-IR analysis of the fiber section revealed the presence of

trace proteins and carbohydrates that are indicative of organic and or

biological material (FT-IR spectra is included in Appendix A, Figure 3).

Supporting data is included in the Procedures and Results section of this report.

Several drops of dilute hydrochloric acid were placed on the foulant material

itself and on fiber surfaces. Bubbles effervescing would indicate the presence of

carbonates. No bubbles were seen on the fiber surfaces.

The module was in good physical condition. A channel was cut in the outer

plastic housing to allow for the harvesting of fibers (See photos in Appendix A,

Figure 1). The majority of fibers were fouled visually with a tan to light grey

colored foulant. Some fibers were pure white and may have been sealed from

water flow during manufacture. These pure white colored tubes were used as

“new” fibers for the SEM/EDX and FT-IR baseline analyses.

SEM/EDX analysis identified fluorine from the fibers themselves along with iron

aluminum silicate clay. Some iron and aluminum oxides may also be present.

Sodium chloride was detected on both the “new” and “fouled” fibers (See SEM

images in Appendix A, Figures 2 and 3). FT-IR analysis of the fiber section

revealed the presence of trace proteins and carbohydrates that are indicative

of organic and or biological material (FT-IR spectra is included in Appendix A,

Figure 4).


EXECUTIVE SUMMARY


Acid test:

be dominant (See SEM image in Appendix A, Figure 2). Fluorine is contributed by

the fibers themselves and is not indicative of the actual foulant. All inorganic

Montgomery Watson – Moss Landing provided one Toray TM820C-400 sea water

reverse osmosis element to Avista Technologies for autopsy. Element serial

number (SN#) was 080441471, and it was labeled “7th position”. Element was wet

tested on San Marcos, CA tap water and data was normalized to seawater

conditions. Elements were weighed and dissected for autopsy. Please refer to

the element drawing in Appendix A for an explanation of terms used throughout

this report.

SN# 080441471 weighed 37 pounds; new elements of this tyyp weigh 32-35

pounds. Normalized wet test data suggests permeate flow is at the high end of

normal range and rejection was 98.6%. Flat sheet cut membrane samples

mimicked full element data showing higher than normal permeate flow on

baseline testing. There was no evidence of mechanical failure (i.e. glue line

failure or delamination), but significant compaction was observed on element

SN# 080441471 (see description in Appendix A).

Exposed membrane surfaces for SN# 080441471 were evenly coated (0.08

mg/cm2 foulant density) with clear to tan colored gelatinous foulant material.

Organic matter dominated foulant material in SN# 080441471, as indicated by a

loss on ignition (LOI) of 97.6%. Vexar feed spacer was free of foulant. Light

microscope analysis showed both Gram positive bacteria and amorphous

organic material are present.

SEM/EDX analysis of foulant material from SN# 080441471 identified only trace

amounts of clay (iron aluminum silicate) and iron oxide as inorganic foulant. FT-IR

analysis identified large amounts of polysaccharides, proteins, and

carbohydrates on SN# 080441471.

Flat sheet membrane coupons were cleaned with RoClean P111 and a second

cleaning was performed using a generic cleaning regime provided by the

customer. Cell test cleaning results are included in the body of this report.

Fujiwara testing was positive for the presence of halogen (i.e. chlorine) on SN#

080441471. It is likely that the membrane surface foulant is masking damaged

(halogenated) membrane surfaces. Once the foulant is removed, the salt

passage increases slightly.


EXECUTIVE SUMMARY


WET TEST

Element SN# 080441471 was wet tested on San Marcos, CA city water, and the

results were normalized to the manufacturer’s published seawater test

conditions. Wet test results are tabulated in the following table.

elements of this model weigh approximately 32-35 pounds.

EXTERNAL INSPECTION

Fiberglass wrap:

The outer fiberglass casing of element SN# 080441471 was in satisfactory

condition.




the development of high differential pressure (usually greater than 12 psi) across

the element. Slight telescoping was observed on element SN# 080441471 (see

photo in Appendix B, Figure 1).

Brine seal:

Brine seal was in good condition and showed no signs of damage that could

allow bypass of the RO concentrate water around the spiral wound membrane

scroll.


The ATD’s are designed to prevent telescoping of element leaves at normal

differential pressures. ATD’s on element SN# 080441471 were in good condition

and showed no sign of physical damage.



Permeate tubes:

No gouges were visible on the ends of the permeate tube that could allow the

by-pass of feed water.


Membrane Surface:

Exposed membrane surface for SN# 080441471 contained a uniformly distributed

clear to tan colored, gelatinous foulant material (See Photo in Appendix B, Figure

1 and 2). Significant compaction was observed on this element (See description

of compaction in Appendix A).

Fujiwara test:

The Fujiwara test is used to confirm that a polyamide (PA) thin-film membrane

has been exposed to an oxidizing halogen, such as chlorine, bromine, or iodine.

The test analyzes qualitatively whether halogens have become part of the

polymer structure through oxidative attack.

The Fujiwara test was positive on samples from element SN# 080441471.

Feed spacer:



feed water passages. Feed spacer in SN# 080441471 is free of foulant (Appendix

B, Figure 3).

Permeate spacer:

Glue lines:


streams. Glue lines in element SN# 080441471 were in good condition and

showed no signs of pouching or delamination.




Membrane samples were tested in a seawater cell-test apparatus to determine

membrane performance characteristics. Manufacturer’s original specifications

are 6500 gpd, 400 ft2 nominal membrane area, and 432 psi net driving pressure.

The permeate flow constant is expressed as the “A” value, and the salt passage

constant is expressed by a “B” value. Both constants are functions of the

chemical-physical properties of the membrane plus any fouling layer present.

COMPACTION

Compaction is defined the deformation of the membrane and membrane

backing material under pressure. There are two possible consequences to

compaction: One is the embossing of the membrane backing into the

permeate (Tricot) carrier material. This results in increased pressure losses on the

permeate side of the element, thus reducing flow, or conversely, requiring higher

pressures to maintain specified flows. The second potential consequence is the

compression of the porous polysulfone membrane support material, which is

sandwiched between the rejecting membrane layer and the polyester backing.

Compression of this layer also reduces flow. However, significant compression of

the polysulfone layer generally occurs only at very high pressures.

A certain amount of membrane compaction is inevitable due to construction

from plastics and textile materials that all deform under pressure. Only when

compaction becomes severe is element performance significantly

compromised.

The effect of embossing of the membrane into the permeate carrier is estimated

by measuring the flux difference between the element and a membrane sample

taken from the element and tested in a cell test apparatus.

Coastal Water Project Particle Size Distribution Determination Study

Introduction The California American Water (CAW) is proposing to implement the CWP (Proposed Project), which includes the construction and operation of a 10 MGD seawater desalination plant near the Moss Landing Power Plant (MLPP), and related appurtenances. A Proponent’s Environmental Assessment has been prepared by the CWP project team and submitted to California Public Utilities Commission (CPUC) for preparation of the EIR. During the EIR preparation, more environmental data was requested by CPUC’ s consultant related to the particle size changes during the filtration process and the effects of the particle size change on the settling characteristics of the discharge. The purpose of this study is to simulate the full-scale flow characteristics of the project and analyze the particle size changes to determine if any significant changes will occur. Background The desalination plant will utilize once through cooling water as feed water. The cooling water intakes of the power plant are located in the Moss Landing Harbor. Under current conditions the water from the harbor is screened at the intake and circulated through the cooling water system. The power plant has two separate power generation systems, Units 1&2 and Units 6&7. Each system utilizes different intakes and cooling water systems. The proposed desalination plant would be connected to Units 1&2. The intake for Units 1&2 is located at the north of the harbor, close to the mouth of Elkhorn Slough. Once the water is circulated through Units 1&2 it is collected at the disengaging basin. The water goes over a trough into conveyance pipes. Cooling water from Units 6&7 is separately collected. The two systems connect prior to discharge through the existing outfall. The existing outfall extends 2,400 ft west through the Moss Landing Harbor and discharges the cooling water close to the Monterey Submarine Canyon. The location of the intakes and the outfall is shown in Figure-1. Any existing particulate matter in the cooling water is discharged through the outfall along with the water. The discharged cooling water is relatively warmer than the ambient seawater which provides a buoyant characteristic to the discharge. In certain times of the day, the salinity of the Moss Landing Harbor water is lower than the ocean water due to the effects of fresh water sources feeding into the harbor. The lower salinity also provides buoyancy to the discharged cooling water. When the cooling water is discharged through the outfall, the existing particulate matter is lifted with the buoyant water and then it settles after all the mixing and dilution takes place and forms the existing settling cone.

The proposed project will integrate a 22 MGD water intake system at the disengaging basin. The once through cooling water will be conveyed approximately 8,000 ft east to the desalination plant by gravity. The desalination plant will include a pretreatment system, an RO system, a post-treatment system and conveyance facilities. The pretreatment system will utilize self-cleaning filters and membrane filtration technology to remove particulate matter to the maximum extent possible. The proposed project does not involve any coagulant addition for pretreatment. However, the ongoing pilot studies might conclude that use of coagulants being essential for successful pretreatment. A final decision will be made once the pilot studies are concluded. Pretreated water will be transferred to the RO system. The final configuration of the RO system will also be finalized after the ongoing pilot studies. The RO system will successfully remove salts and other contaminants and the product water will be compliant with drinking water standards. As a result of desalination through the RO process, 10 MGD of permeate and approximately 12 MGD of concentrate will be generated. Prior to distribution into the water system, permeate will be post treated for stabilization and disinfection. The conveyance facilities at the plant site will convey the product water to the distribution system. During the treatment process, following the 100 μm initial filtration for large solids, the membrane pretreatment system will remove suspended solids from the feedwater. The final selection of the membrane manufacturer is to be concluded in the final design and construction phase. Depending on the manufacturer, membrane systems could follow an inside-out or outside-in filtration pattern. When outside-in membranes are used the hollow fibers are submerged in feedwater and a vacuum is provided on the inside of the

3

fibers. The filtered water then is conveyed to a storage tank. When inside-out membranes are used, a pump pressurizes the feedwater and pushes water through the hollow fibers. The filtered water outside the fibers is collected in a storage tank. In either case particulate matter accumulates on the membrane surface. The accumulated suspended solids are then backwashed approximately every 30 minutes. The backwash process is specific to each manufacturer but in general, pressurized air is provided to the system with filtered water in the reverse direction of filtration. The particles are removed from the membrane surface by the applied air and backwash water. Backwash wastewater will then be pumped into the already pressurized concentrate line and the combined flow will be returned to the cooling water system. The pressure in the line will convey the combined flow to the MLPP site through a 8,000 ft, 24-inch pipeline. The 24-inch pipeline will connect to the same disengaging basin but downstream of the desalination plant intake. This will prevent concentrate recirculation into desalination plant intake system. The desalination return water (combined concentrate and backwash wastewater) will be mixed with cooling water flow at the disengaging basin and follow the same discharge route to the outfall. Theoretical Considerations Practically, particles in water can be classified as suspended and colloidal in terms of their settling characteristics. Suspended particles are generally larger than 1µm in diameter and settle easily with gravity. Particles with the size of 0.01 - 1 µm in diameter are considered as colloidal particles that do not tend to settle with gravity. Colloidal particles in natural waters generally have a net negative surface charge. The repelling forces of the common electrical charge on the particle surfaces are much greater than the attractive body forces (van der Waals) between particles, thus, naturally colloidal particles disperse uniformly throughout the liquid. The dispersed colloidal particles move randomly (Brownian motion) in the liquid. Depending on the reduction or the elimination of the surface charges, particles may collide successfully to form larger particles. Under natural conditions, colloidal particles do not tend to aggregate unless the surface charges are eliminated. The surface charges on the colloids can be eliminated (destabilization) by chemical means (i.e. coagulants). When the electrical repulsion decreases, the attractive body forces overcome the repelling forces, thus, collisions between particles result in aggregation. The aggregates settle more rapidly with increasing size, since the settling characteristics of the particles are directly related with the particle size. In addition to the interactions between particles, particle size is also governed by the shear forces acting on the particles in a liquid. Following formula describes the relation between the particle size, shear force acting on the particle, and energy loss during the course of a conveyance system. (Where, Sh is the shear force, is the change in pressure, ρs is the particle density, ρ is the liquid density, g is the gravitational acceleration, and D is the particle size)

gDS

sh )(

For a given particle size, shear force acting on a particle is directly proportional to energy loss due to the friction. In other words, higher head-loss in the conveyance elements creates higher shear forces acting on the particles.

As mentioned above, the suspended solids are removed by the membrane treatment process. The particle size could potentially increase during the filtration process and with the backwash process; the enlarged particles could then be discharged into the ocean. However, the enlarged particles in the filter backwash wastewater will pass through various processes and conveyance pipelines before being discharged into the ocean. These processes will provide mixing and shearing energy to the water, which could lead to breakdown of the enlarged particles to original size. These locations are listed and described below: Location # 1 Membrane filtration backwash process: As indicated above, the

membrane filtration elements are backwashed every 30 minutes by air scouring and flow in reverse direction. This process provides a significant energy and creates turbulence in the filter housing. The initial studies will investigate this location for potential particle size changes.

Location #2 Injection of the backwash wastewater into pressurized concentrate

pipeline: The backwash volume from membrane filtration elements will depend on the specific manufacturer. The backwash wastewater will pass through a pump, which will provide energy and turbulence to the water, for pressurization in order to be combined with the RO concentrate in the pressurized return flow pipeline. For any manufacturer, the backwash wastewater volume will be a small proportion when compared to the concentrate flow. When backwash wastewater is injected into the concentrate line, the blending effect in the line will impact the particle size.

Location #3 Conveyance of the blended water to the disengaging basin: The blended

concentrate and backwash wastewater will be conveyed to the disengaging through the proposed 24-inch, 8,000 ft return-flow pipeline. The energy drop due to friction and minor losses in the pipeline is directly related to the shear force that could break down the enlarged particles.

Location #4 Discharge into disengaging basin: A significant energy loss and mixing

will be observed as the blended concentrate and backwash wastewater is discharged into the disengaging basin.

Location #5 Conveyance from the disengaging basin to the connection point with

Units 6&7: Once the concentrate and backwash wastewater is blended with the cooling water at the disengaging basin, a 350-ft of pipeline will convey the water by gravity to the tunnel structure prior to blending with cooling water from Units 6&7. Similar to location 3, energy losses in the line will contribute to breakdown of particle size.

Location #6 Drop of the overall combined flow into tunnel structure: Blended

concentrate and backwash wastewater, cooling water from Unites 1&2 and cooling water from Units 6&7 will blend in the tunnel structure prior to discharge through the outfall. The overall blended flow could be up to 1.2 BGD.

Location #7 Conveyance of the overall combined flow in the outfall pipeline: The

outfall carries the overall combined flow for final discharge. Energy losses in the in the 2,400 ft outfall would contribute to particle size reduction.

5

Location #8 Discharge of the overall combined flow through the discharge structure: The energy losses related to the discharge (including minor losses through a sudden expansion) of the overall blend through the outfall structure would contribute to particle size reduction.

Location #9 Blending and dilution of the overall combined flow within the discharge

zone: Once the overall blended water is discharged into the ocean, the dilution and existing currents could impact the particle size distribution in the discharge.

Experimental Procedures To understand the particle size distribution in the feed water, samples will be collected before the membrane filters and analyzed by using a HACH WPC-21 particle counter. The results obtained from this preliminary analysis will be used to calculate conceptual parameters such as the particle mass distribution, the settling velocity, and the horizontal settling distance for all particle size ranges. These parameters will be utilized to model the deposition rates of particles to the ocean floor within a calculated proximity to the discharge chimney. The experimental efforts will continue to analyze the above mentioned parameters and deposition rates in the critical locations that are given in the Theoretical Considerations part in a step-wise manner if the calculated theoretical deposition rate exceeds the assumed level of significance of 1mm/yr. As mentioned above, following the initial feed water analysis the membrane filter backwash process (Location 1) will be studied for potential impacts on the particle size distribution (Figure 2). The conceptual parameters and the particle deposition rate will be calculated and modeled to validate that the change in the rate of accumulation is less than 1 mm/yr. If not, the process locations will be examined to observe the effect of energy dissipation on particle size distribution and the deposition rate. Data Analysis Water samples have been collected to determine the particle size distribution in the feed water (FW) and in a mixture of waste backwash water and concentrate that is representative of the full-scale. Concentrate and ultra-filtration backwash wastewater (UFBW) would mix at an approximate ratio of 1/10 during full-scale operations. The 10 MGD desalination plant would generate approximately 11 MGD of concentrate and 1 MGD of UFBW. For sampling purposes, 1.5 L of UFBW was mixed with 15 L of concentrate and the mixture was fed to the particle counter. Five backwash events were separately sampled and analyzed. The raw particle count data collected during the study is given in Tables 1 and 2 in the Appendix. Tables 3 and 4, also located in the Appendix, provide the data and statistical analyses that are used in this study. The samples obtained from the individual sampling points are considered as replicates for the five sampling events. The mean, standard deviation, and 95% confidence intervals are calculated for the sampling points.

Figure-5 Percent Particle Count vs Particle Size

The shift in particle size distribution from smaller particles to larger particles can be observed from Figure-5. The percentages of 1-2 µm and 2-3 µm particles are shifted to larger particles sizes of 3-25 µm. As can be seen in Figures 3 and 4, seven percent of the particles in the size range of 1-2 µm and 3.2 percent of the particles in the size range of 2-3 µm (total of 10.2 percent within the size range of 1-3 µm) are aggregated and formed larger particles within the size range of 3-25µm (3.1, 3.1, 2.3, 1.2, and 0.5 percent for the particle size ranges of 3-5, 5-7, 7-10, 10-15, and 15-25 µm, respectively). The particle count data was used to calculate the average particle mass for the size ranges determined by the particle count test results. For the calculations all particles are assumed as spherical. For a given particle size range (i.e. 1-2 μm, 2-3 μm, 3-5 μm etc) the average particle diameter is accepted as the arithmetic average of the range (i.e. for range of 1-2 μm, average particle size is 1.5 μm). Particle density was assumed as 1.3 mg/mL (1300 kg/m3) for the calculations. Calculation tables are given in Tables 5 and 6 in the Appendix.

Figure 6 shows the calculated particle mass with the assumed average particle diameter in the FW and UFBW. Figure 7 presents the cumulative mass distribution of the particles with assumed average particle diameters. In the feed water, the incremental average particle diameter with the highest mass fraction (27.2 percent) is 8.5 μm. In the mixture, the incremental average particle diameter with the highest mass fraction (27.9 percent) is 20 μm. Discussion As previously described in the Introduction and Background, the proposed seawater desalination facility will utilize Moss Landing Power Plant’s cooling water as feedwater. For discussion purposes, the average flow rate of waste cooling water from the power plant is assumed to be 640 mgd, and the assumed average suspended solid concentration in the cooling water is assumed to be 20 mg/L. The calculated mass of suspended solids in the cooling water that is discharged daily to the ocean is around 107,000 lbs/day. The proposed project will utilize 22 mgd of MLPP cooling water for feedwater, therefore, the daily mass of particles that may be affected by the desalination facility is calculated to be 3,700 lbs/day, which is roughly 3.4 percent of the particle mass that is currently discharged to the ocean by the cooling water return line. The previously discussed study of the membrane filter backwash concluded that 10.2 percent of the particles in the feedwater were aggregated to a larger particle size, as measured in the UFBW/concentrate mixture. Therefore, during the actual operation of the seawater desalination facility, 0.35 percent (10.2 percent times 3.4 percent) of the total particles present in the combined desalination plant return and cooling water flows may aggregate to form larger particles within size range of 3-25 μm. This ignores the additional breakdown of the enlarged particles that could occur at downstream locations previously described (Locations 2 through 9). Particle mass analyses indicated that the average particle sizes of 8.5 μm and 20 μm contribute the highest percentage of particle mass for the feed water and the mixture, respectively. Settling characteristics of these two particle sizes can be compared by using settling velocities. Stokes’ law can be utilized to examine the settling velocities of the particles with the given particle sizes. To assume the worst-case situation, the buoyancy forces caused by the water salinity and temperature of the discharged water will be neglected. To calculate the settling velocities, laminar flow conditions with the Reynold’s number (Re) less than or equal to 0.3 is assumed. Under these conditions, the settling velocity of a particle is given by Stokes Law:

18)( 2dg

V sc

Where; Vc: terminal velocity of particle (m/s) g: gravitational acceleration (m/s2) ρ: density of fluid (kg/m3) ρs: density of particle (kg/m3) d: diameter of particle (m) μ: Dynamic viscosity of fluid (Pa.s)

12

Seawater at 20°C has a density of 1,025 kg/m3, and dynamic viscosity of 1.08 x 10-3 Pa.s. The gravitational acceleration is accepted as 9.81 m/s2 and particle density is assumed as 1,300 kg/m3. Under these conditions, the settling velocities are calculated as 1.0x10-5 m/s (3.3 x10-5 fps) and 5.6x10-5 m/s (1.8 x10-4 fps) for the particle diameter of 8.5μm and 20μm, respectively. The ocean current velocity is assumed to be 0.1 fps. Compared to the settling velocities calculated above, the horizontal velocity is 555 and 10,000 fold larger than the settling velocities of 20 μm and 8.5 μm particles, respectively. To calculate the horizontal distance form the discharge chimney that will be affected from the particle deposition, the particle size of 20 μm is chosen due to its higher settling velocity. The distance between the top of the discharge chimney and the ocean floor is 20 feet. The water depth at the same location is 40 feet. For discussion purposes, the particles are assumed to start settling from 30 feet above the ocean floor with the settling velocity of 1.80 x10-4 fps. The horizontal current velocity acting on the particles is assumed to be 0.1 fps. Under these conditions, the maximum horizontal settling distance is calculated as 3.1 miles (16,500 ft). To calculate the deposition rate, a unidirectional current (from north to south) with the velocity of 0.1 fps, and the impacts of waves are assumed to be the two major forces acting on the particles that leave the discharge chimney. A minimal dispersion towards the opposite direction of the waves is assumed with the angle of dispersion of 5° (Figure-8). Under these conditions the trapezoidal area that is affected by the deposition is calculated as 28.3 million ft2. Under the current situation (without the proposed desalination facility), the rate of mass of particles that is transferred to the ocean by the cooling water return line is calculated as 107,000 lbs/d. If 20 μm particles and larger are considered due to their higher mass and settling velocities compared to the other size ranges, their contribution to the particle mass discharge is calculated as 17,000 lbs/d which constitutes for 16% of the total particle mass. If the bulk particle density is accepted as 66 lbs/ft3, the settling rate is calculated as 1.02 mm/yr. Following the operation of the desalination plant, approximately 3,700 lbs/d (3.4% of the total mass) of particles will be discharged to the cooling water return line from the membrane filtration backwash. Again, if the particles with the size of 20 μm and larger are considered (which constitutes for 20.6% of the total mass), 756 lbs/d of particle mass will be discharged to the ocean. Assuming a bulk particle density of 66 lbs/ft3, the deposition to the conceptual accumulation zone is calculated as 0.05 mm/yr. Since the particle load to the desalination plant is 3,700 lbs/d, 103,000 lbs/d (96.6% of total particles) of particle mass will reach to the discharge chimney unaffected. The deposition that constitutes to this portion of particles is calculated as 0.98 mm/yr. Thus, following the desalination plant operation, total deposition to the conceptual accumulation zone will be 1.03 mm/yr (0.05 mm/yr from the desalination plant and 0.98 mm/yr from the unaffected cooling water return). Based on the flow scheme given in Figure-8 and the assumptions mentioned above the change of accumulation rate before and after the desalination plant operation is calculated as 0.01 mm/yr (1.02 mm/yr before, 1.03 mm/yr after).

13

Figure-8: Conceptual accumulation zone

Conclusion and Recommendations: The preliminary results of the particle size distribution determination study indicated that the UF application slightly increases the particle size and distribution of particles returned to the ocean. The preliminary data showed that 10.2% of the particles in the size range of 1-3 μm aggregate to larger sized particles in the size range of 3-25 μm. When the overall system is considered, only 0.35% of the total particles that are currently being discharged to the ocean may aggregate to form larger particles, as a result of the full-scale desalination project. This estimate is certainly high because it does not take into account the additional breakdown of the enlarged particles that could occur at downstream locations previously described (Locations 2 through 9). The settling velocities of particles with the diameter of 8.5 μm and 20 μm were calculated to illustrate the settling characteristics of these particles that contribute the highest mass percentage throughout all particle sizes. Under laminar flow conditions, the settling velocities of particles with the diameter 20 μm are 18 times more than the particles with the diameter of 8.5 μm. However, these velocities are as much as 10,000 fold lower than the known average ocean current velocities, thus the settling location of the particles is governed mostly by ocean currents. Furthermore, storm events would be expected to be a significant factor in re-suspending and redistributing settled particles. Based on the settling velocities and the current velocity, horizontal effective maximum settling distance of particles with the size of 20 μm and larger is calculated as 3.12 miles. By assuming a minimal dispersion in addition to the unidirectional current and wave impact, the conceptual area that is affected by the particle deposition is 28.3 million ft2. The difference between the theoretical accumulation rates before and after the desalination plant operation is 0.01 mm/yr which is 100 fold less than the assumed level of significance. This is an apparent indication that the particle aggregation during the membrane filtration is insignificant in terms of its negative impacts on the particle deposition on the ocean floor.

14

The preliminary results indicate that the full scale desalination project will not cause a significant or measurable change to the amounts or patterns of particles settling to the ocean floor, when compared to existing power plant operations. Additional sampling and analysis of downstream process locations would merely serve to validate the additional breakdown of the enlarged particles to their original sizes. Therefore, the objectives of the Study have been met and further sampling and analysis is not considered necessary.
