Where Technology Meets Technology

A Vast Audience, Diverse Media Options

Over the last 1,000 years, numbers have

been applied to every aspect of our work

and leisure. The measure of time, space,

matter and effort pervades mechanics,

chemistry, physics and virtually every other

science and art.

This is so, it is said, because the con-

cepts of arithmetic generalize an enor-

mous amount of experience and reflect,

in abstract form, those relationships in the

actual world that are met with constantly

and everywhere.

Its pretty impressive. But you havent

seen anything yet, compared to whats

coming.

Thats because every single human

endeavor that numbers have managed to

worm their way into over the last 10 centu-

ries, the computer, in only the last 50 years,

has followed. Now, with billions of comput-

ing nodes in place, the mass collection of

data has begun. We have the sheer com-

putational power, databases and algorithms

to analyze that data in ways unrealizable

through human intuition or insight.

Computers plus data analytics already

not only beat humans at chess, they tell

us how to play baseball, basketball and

football. And they never bore you with

anecdotal stories about the old days, like

coach did.

Quantities & qualities

As far as exploiting super-computing, the

oil & gas industry builds terrestrial models

as complex and data-intensive as anything

coming out of the Department of Defense.

If anything calls out for the measurement

and analysis of its mass quantities it is wa-

ter. We already see the emergence of smart

water networks and even smart cities. Yet

when it comes to the on-going colonization,

I mean computerization, of lived worlds, the

biggest single challenge remains integra-

tion, as successive generations of comput-

ers are installed on top of those preceding,

like Romes Catholic churches serenely

sitting atop buried pagan chapels.

This is clearly the case in water indus-

tries. To be successful with smart water,

says Gian Francesco Imperiali, head of

ABBs water-industry sector initiative, smart

grid solutions must be seamlessly inte-

grated with other systems, which include

traditional meters as well as cyber-security

and analytical software.

But established technologies and appli-

cations werent meant as system solutions.

A great deal of restructuring is required for

automation and control, analytical tools, cy-

ber security and cloud storage to function

together, Imperiali says.

More down to earth

Mobile computing allows capture of

thousands of data points recorded daily

and the store of results in SQL databases.

From there, logic is applied to the data

along parameters that include temperature,

pressure and ph. Automated reports and

relevant work orders are generated.

When a facility has operator, lab and

analytic solutions, having it all together

speeds the validation and availability of in-

formation, says Mark Cowley of operations

software vendor, Flex Systems.

Its the same with machine-to-machine

talking. Its important and more or less

par for the course, says Kevin McFadden

of scale and instrument provider Mettler

Toledo, to move weigh scale readings into

a database for portal information-sharing.

Thats something we do well, whether the

application is small or large.

What must be more common and

what is more challenging is moving a rel-

evant set of this operations data to the level

of the business systems. Data historians act

as an intermediary in this regard.

Large business-system vendors such as

SAP and Oracle realized a decade ago the

future wasnt recording transactions and

managing resources, but making full use

of the data, including in ways that cant be

foreseen.

Many outstanding examples of industrial

uses of big data, super-computing and

plant-floor to top-floor computing exist,

including in the water industries.

What were saying is that soon it will be

everywhere.

Especially during high-demand

periods, the North Lauderdale

Water Assoc. of Bailey, Missis-

sippi, was challenged to remove

iron from its drinking water.

When first established in 1966, the as-

sociations footprint consisted of a single

well pumping 250 gallons per minute,

one iron-removal filter, about 62 miles of

distribution lines and two 200,000-gallon

storage tanks.

Today the association includes seven

wells and four iron-removal treatment

plants. Distribution lines have grown to

cover about 800 miles and there are six

storage tanks, for a combined treatment

of 3,120 gallons per minute and storage of

1.2 million gallons.

The problem at the water treatment facil-

ity was that the treated water was short-

circuiting filters, says Stanley Spradling of

Calvert Spradling Engineers, West Point,

Mississippi.

The reason for it happening was inade-

quate storage. During high-demand periods,

treated water was sucked through the filters.

This prevented them from working efficiently

to remove the iron and other organics.

Spradling and his colleagues modified

the treatment process for additional stor-

age capacity, allowing the treated water

from the filters to gravity flow into a clear

well tank. But for that, a tank was needed.

Costs sunk in concrete

The wrinkle there was that the price for

the kind of concrete storage tank that it

was first assumed would be used for the

project turned out to be significantly higher

than budgeted.

That gave Southeastern Tank of Leba-

non, Tennessee, an opportunity to furnish

a quotation for a glass-fused-to-steel tank,

says the companys Marc Nichols.

It did so after determining that a 59 ft.

x 10 ft., 200,000 gallon Aquastore tank

from CST Storage would support the

modified treatment process. And on that

basis, Southeastern Tank was awarded the

project.

In order for the gravity-fed system to

work with an above-ground tank, the plant

site had to be reworked to help with drain-

age. Control ditches and drainage pipes

were installed. Backfill was not required

as a means to partially bury the tank. That

saved construction time and money.

The tank was completed and installed

on-time.

As noted, the additional storage means

the plant can now pump 800 gallons per

minute and store 1.2 million gallons per

day. In addition, iron further settles out in

the tank, helping to improve water quality

for 4,000 customers.

Accurate lead times mentioned

Spradling says the association is

extremely pleased with the performance

of the Aquastore. The interior and exterior

coatings have stood up well and the tank is

pretty well maintenance free.

Besides its fast, economical construc-

tion and low maintenance costs the tank

never needs painting.

The Southeastern Tank Team is profes-

sional, with especially good attention-to-

detail, Spradling concludes. They do an

excellent job providing accurate estimates

as many projects have a one- to two-year

lead time.

CST Storage is a global provider of mod-

ular, factory-coated bolted storage tanks for

dry-bulk and liquid applications in munici-

pal, industrial and agricultural markets. The

company is the result of the merger of En-

gineered Storage Products Co., producer

of brand names Aquastore, Harvestore and

Slurrystore, with Columbian TecTank (CTT).

The company has several fabrication and

engineering centers in the U.S. Its head-

quarters is in Kansas City, Missouri.

Mine tailings disposal, and its impact on

water usage, is an important concern for

any mining company. The challenge today,

whether extracting aluminum, zinc, gold or

iron ore, is how to dispose of tailings mate-

rial such that it is contained and stable,

while maximizing water reuse and minimiz-

ing surface footprint.

Paste, or thickened tailings, has become

an increasingly important method to ad-

dress many of the environmental problems

facing the mining industry. Pasting was

originally developed by the alumina indus-

try in the 1970s, and for the past 20 years

has been applied worldwide.

Yet today, less than 1 percent of iron ore

mines employ systems for paste thicken-

ing, despite its benefi ts for tailings disposal

optimization.

Nevertheless, mining projects in devel-

oped countries conform to stringent water

conservation and environmental standards

in tailings disposal, and developing na-

tions too are instituting signifi cant steps to

require water reuse and mitigate environ-

mental damage.

In Chile, for example, where coastal de-

salinization plants are needed, water reuse

is critical, prompting mining operations to

explore the most effi cient options for water

reclamation in tailings disposal.

In Perus huge mining sector, and similar-

ly in Brazil, stiffer environmental regulations

are in place for mining operations today.

Once tailings dams are a failure risk, near

capacity or unstable, only immense capital

investment can rectify the situation. Yet,

many mines could minimize or delay exor-

bitant cost by reducing water volumes put

into their tailings disposal facilities. They

would thereby improve capacity and stabil-

ity, while reclaiming more water for reuse in

upstream washing, screening and jigging.

Location given

Water reuse in mining tailings disposal

is particularly critical in arid and semi-arid

environments where water availability is

limited and usage closely regulated by

government mandates for example, in

the semi-arid climate of South Africa. There,

one iron ore mining operation has success-

fully adapted its tailings disposal and water

reuse procedures to this environment, i.e.,

the Khumani iron ore mine in Northern

Cape Province.

Iron-ore deposits are found about 60

kilometers north of the Beeshoek mine

on the Bruce, King and Mokaning (BKM)

farms, adjacent to Kumbas Sishen iron ore

mine. The Khumani mine is part of Ass-

mang Ltd., jointly owned and controlled

by African Rainbow Minerals Limited and

Assore Limited.

Since 2008, Khumani has produced

about 16 million tons of product annually.

After primary and secondary crushing,

iron-ore processing involves wet washing

and screening, jigging, and fines recov-

ery using de-grit cyclones. It all requires

water in large volumes and the mines

success is dependent on water recovery.

This area is a semi-arid climate, yet it

supports a number of large mining opera-

tions, and an ever-growing local popula-

tion and assorted infrastructure, so there

is a limited quantity of water available

for distribution by the Sedibeng water

management board, says Thomas Du

Toit, metallurgical manager, Assmang Iron

Ore. This created a number of challeng-

es for the Khumani mine, as our preferred

process involved wet processing, but we

did not have the available water.

High evaporation rates were a fact of

life and suitable sites were lacking for a

conventional tailings facility, continues Du

Toit, We needed to design a system that

could recover most of the water, and not

lose a large percentage to evaporation.

Thickeners as clarifiers

To maximize water reuse, the Khumani

plant contracted with WesTech Engineer-

ing, Inc. to design and implement a two-

stage tailings thickening process. The first

stage consists of two primary high-rate

traction slurry thickeners, each 295 feet in

diameter, situated at the main plant. The

first was installed in 2008, with the open-

ing of the mine. The second was added

in 2012 to accommodate a 100-percent

increase in throughput capacity.

The thickeners operate as clarifiers, return-

ing the bulk of clarified water to the main

plant at the combined hydraulic flow rate

of 525,000 to 635,000 cubic feet per hour.

These thickeners recover approximately 90

percent of the slurry water by volume.

Most mining facilities would then deposit

the tailings slurry direct into a tailings pond

at about 40 percent to 50 percent solids. But

this high-rate primary thickener was inad-

equate to produce slurry densities required

Mining industry

for the desired water reclamation.

WesTechs solution used paste thicken-

ing technology to facilitate a second-stage

tailings thickening process. Dilute slurry

from the primary thickeners is pumped a

distance of approximately three miles to

an area with adequate storage capacity for

the expected 25-year life of the mine to

feed two 59-foot diameter paste thickeners

at the plants paste disposal facility. The first

paste thickener was put into place in 2008,

and the second installed in 2012.

Size of the two secondary paste thick-

eners was determined from the residence

time required for the slurry to reach terminal

solids concentration, says Philip Lake,

WesTechs international business unit

leader. Each accommodates feed ton-

nages varying from a minimal 147 tons per

hour to 300 tons per hour. Volumes up to

450 tons per hour can be buffered in each

of the secondary paste thickeners for short

periods of time. The paste thickeners re-

cover at least 75 to 80 percent of the water

by volume from the primary thickeners,

increasing total water reclamation in excess

of 95 percent. These rates ensure adequate

capacity in the thickeners to achieve high-

density paste.

Dimensional relationships

The paste disposal facility requires a

minimal solids concentration of approxi-

mately 58 to 60 percent by mass, in gen-

eral. This is due in part to enable pumping

of the thickened slurry to the outer limits of

the dam wall using centrifugal pumps, but

also to allow the material to be deposited

in layers of less than 4" to ensure effective

drying and consolidation.

The facility was designed as an impound-

ment of compacted earth embankments

into which the tailings stream is deposited.

Construction is phased, with the facility built

to accommodate tonnage expansions.

Khumanis secondary paste thicken-

ing process delivers substantial benefits,

Lake says. Not only does it recover water,

which can be reused in the plant, but it also

leaves less water in the deposit site. In a

paste disposal, because of the nature of

paste tailings, the particles within it are well

distributed.

As Lake explains, coarse particles, 200+

microns in size, are uniformly intermixed

with the finer material of less than 20 mi-

crons.

Therefore, in the non-segregating

deposit, he explains, this homogeneous

particle distribution facilitates water be-

ing pulled up to the surface by capillary

suction where it can be evaporated. In ad-

dition, the beach angle of the deposition

forces frees water to accumulate at the

low point of the PDF, to be collected and

reused by the plant.

Explaining a difference

The process is quite different, however,

in a conventional slurry tailings dam,

Lake continues.

The slurry segregates into coarse

material that settles out first at the deposi-

tion point, he says, and the ultra-fines

are carried further into the tailings facility.

Because the ultra-fines have segregated

from the coarse material, they do not tend

to settle over time, and the free water on

the tailings pond cannot be reclaimed for

reuse, as is.

The result is a long-term wet deposi-

tion with liquid fractions inside the tailings

pond, which if breached can result in dam

failure. This condition is unlikely to occur

with paste deposition where balanced

distribution of course and fine particles,

coupled with reduced water content,

deliver compact space use and better

structural integrity within the tailings dam.

An additional benefit is that paste tails

tend to dry and form a hard crust. Con-

ventional tailings have a fine powder

deposition that can create dust pollution.

Studies indicate thickened paste tailings

can reduce tailings dam construction up

to 40 percent, both in material quanti-

ties and capital costs, and allows flexible

options for dam locations, compared to

conventional slurry systems.

The Khumani project demonstrates it

is possible to build and operate a wet

processing iron ore mining operation in

an arid environment where water supplies

are limited, providing an integrated design

philosophy and sound engineering prac-

tices are in place.

Two-stage water recovery and paste

disposal has been successfully imple-

mented at Khumani Iron Ore Mine in a

unique installation, by any standard, Du

Toit says. Combined use of primary and

secondary thickeners in iron ore mining

has rarely been implemented.

A large 295-foot diameter primary thick-

ener is integrated with a secondary paste

thickener located three miles away at the

paste disposal facility.

The system provides long-term envi-

ronmental and cost efficiencies that few,

if any other iron ore mining facility, can

realize, Du Toit says.

can realize.

The city of Palm Coast, Florida, was ex-

periencing elevated color in a concentrate

stream typically directed to a lime-softening

facility for recovery as drinking water.

Water-quality efforts directed at meeting

the lime plants secondary-color standards

limited the concentrate volume able to be

recovered.

In consultation, Palm Coast city staff and

Sanford, Florida-headquartered CPH Engi-

neers identifi ed use of ozone as one good

way to reduce color from the concentrate

stream. Pilot-testing demonstrated that

ozone could effectively address the color

issues and improve concentrate quality to

the lime plant. It would also be the lowest-

cost alternative.

Having decided on the best course of

action, both project-budgeting and -sched-

uling issues were signifi cant challenges

for the city in its efforts to receive grant

funding.

Ozone-related innovation

As is well-known, ozone is an inorganic

molecule with the chemical formula O3.

It is

a pale-blue gas with a distinctively pungent

smell. Ozone is a powerful oxidant and has

many industrial applications. Ozonation is

the process of infusing water with ozone

and is used to facilitate organic breakdown.

To start, several oxidative treatment

processes were piloted in efforts to reduce

concentrate color.

Based on pilot-testing results, the city

chose the Summit Series system from

Pinnacle Ozone Solutions, Cocoa, Florida.

The ozone system chosen was selected

based on its perceived ability to offer the

greatest functionality and lowest total

lifetime cost. It is able to match ozone pro-

duction to real-time demand via automatic

control of the ozone generator platform and

three injection process trains using on-

demand controls.

In practice, it is said, so-called corona

discharge is the only practical way of mak-

ing ozone in the quantities required for

municipal scale applications. Pinnacle says

its differentiator is a modular ozone cell is

calls the "Quadblock." The call has a high

frequency power supply and microproces-

sor control connected to four fl at-sheet

ceramic dielectric elements, allowing for

compactness, energy effi ciency and mini-

mal maintenance.

Onward to installation

Pinnacle Ozone Solutions worked with

city staff and CPH engineers to implement

a comprehensive ozone system. Pinnacle-

provided pilot equipment and process-

optimization services were used to validate

the applications parameters. An integrated

design approach culminated

in specifi cation of an onsite

oxygen generator, modular

ozone generator, closed-loop

chiller system, Venturi-based

ozone-injection system and

ozone-off gas-destruct system.

The ozone system was im-

plemented in the fall of 2014.

It reduces organic-based color

of the low-pressure reverse-

osmosis system concentrate

stream. As signifi cant, in an

innovative and unique treat-

ment application, this pre-

treated concentrate stream is

processed as an alternative

water source at the citys lime

softening facility.

The process allows recovery

and treatment of up to 750,000

gallons per day of alternative

water supply that otherwise

would have been discharged

to waste. Dissolved color of

the concentrate stream was

reduced from 62 to less than

30 true-color units.

A unique aspect of the

project is control of the

ozone dose based on both

dissolved-ozone and dis-

solved-color. Dissolved-ozone

probes provide feedback to

the controls for the ozone-in-

jection process. However, the

dissolved-color meter provides

the fi nal-compliance point and

allows for automatic adjust-

ment of the ozone dose. The

integrated system automati-

cally adapts and compensates

for changes in the plants

concentrate-water quality.

Final words

As mentioned, a signifi -

cant project challenge was

budget and schedule. To

qualify for available Florida

Department of Environmen-

tal Protection and St. Johns

River Water Management

District grant funding, the city

needed to complete the entire

ozone project in less than six

months. Pinnacle Ozone Solu-

tions manufactured and de-

livered all the ozone-process

equipment within six weeks of

receiving the purchase order.

Installation was completed

working with the contractor

Sawcross, Inc., of Jacksonville,

Florida. At startup and testing,

initial system results exceeded

performance goals. Pinnacle

delivered and substantially com-

pleted a fully integrated ozone

system within the schedule

needed to receive grant funding.

The improvement made in water color was clearly visible to the eye.

Its a fact and somewhat uncomfort-

able making that wet-wipe consumption

has almost tripled the past decade, accord-

ing to industry analyst Smithers Pira.

For consumers, wipes are effective,

clean, convenient and easy to use. But pa-

per towels, diaper liners, cleaning clothes

and hygiene-, cosmetic- and baby-wipes

reach wastewater-treatment plants and

pump-station manual bar racks and pumps

relatively intact.

There they clog screens, jam equipment,

and increase maintenance, repairs and

costs. According to the Association of the

Nonwoven Fabrics Industry (INDA), fi eld

tests conducted with utilities show that

the wastewater system impact of non-dis-

persible debris breaks down to 50 percent

paper towels, 25 percent baby wipes, and

25 percent hygiene, household cleaning

and cosmetic wipes.

For decades, plant operators dealt with

periodic plugs, but more use of disposable

wipes and other non-dispersibles acceler-

ate the problem for wastewater treatment

systems.

Impact on pump stations

Found upstream from treatment plants,

pump stations are on the front lines when

it comes to attack from non-dispersible

products. Station upgrades primarily

focus on pump replacement, leaving the

original-equipment coarse-bar screens

intact. These screens, some installed 30 to

40 years ago, with 2 to 2-1/2 openings,

may have performed well for decades, but

now prove inadequate to stop increased

non-dispersible fl ows, meant to pump right

through to treatment plants. The headworks

in many plants, however, also utilize coarse

screening, allowing non-dispersibles to

negatively impact pump and mixer opera-

tions a costly outcome.

To compensate for higher concentrations of non-dispersible debris, many plant operators have had to increase lift-station pump horsepower to maintain fl ow rate.

through the pump stations. Debris clean-

out, maintenance and repair has to be

done more often. Draining the pipes and

disposing of waste plugging at the lift sta-

tions is tedious and unsafe work within

tight space constraints. Workers enter lift

stations 30 to 40 feet underground, wear-

ing Tyvek suits, rubber gloves and safety

glasses, and carry the waste material

up fl ights of stairs for disposal in waste

receptacles above ground a labor-

intensive and costly operation.

Whats more, to compensate for

higher concentrations of non-dispersible

debris, many plant operators have had to

increase lift-station pump horsepower to

maintain fl ow rate.

Examples success

Reducing the impact on costly-to-

maintain-and-replace plant systems can

be mitigated by better managing non-dis-

persible debris upstream, at the lift sta-

tions. An excellent example of how this

can be achieved is the recent upgrade to

the Arizonas Sun City lift station, owned

and operated by EPCOR Water.

EPCOR Water is a utility company

based in Edmonton, Alberta. It manages

numerous municipal water and wastewater

treatment facilities throughout Canada and

the United States. Its a division of EPCOR

Utilities, Inc., which builds, owns and oper-

ates electrical transmission and distribution

networks throughout Canada and the U.S.

The company provides water and waste-

water services to more than one million

people in over 85 Western Canadian com-

munities and industrial sites. It is also the

largest private regulated water provider in

Arizona and New Mexico.

What we had was very antiquated

screening technology, installed in the late

1970s, says Douglas Griffi th, operations man-

ager, EPCOR Water. The upstream coarse 2"

screen was very ineffi cient, letting just about

everything through that was smaller than a bed

sheet or a towel. The screen was not designed

to deal with a high volume of non-dispersibles

that the lift station was experiencing.

Consequently, indicates Griffi th, the

pumps pushed most of this non-dispersible

debris to the plant several miles away, where

much of that ended up weaving itself into

big masses of material that would jam the

plant pumps and mixers. It was costly.

Earlier, we had switched-out our existing

lift station pumps to larger 250 horsepower

slurry pumps, which were much bigger than

what we needed for the fl ow, but necessary

to deal with the debris. This solved our fl ow

rate problem, but the lift station was still

passing on all of this debris to the plant,

says Griffi th.

ible debris to the plant several

Trouble downstream

Yet not all the non-dispersible debris

passed through the lift station pumps.

Some was trapped in the coarse screen

and needed to be cleaned out about every

two weeks. Two workers descended 30

feet underground through a narrow vertical

passage to remove the material and bring it

back to the surface.

Cleaning debris from the lift station

screen was very awkward and unsafe,

says Griffi th. We were progressively having

to do this more and more frequently. We

defi nitely knew it was time for an upgrade.

Most solutions that Griffi th and his team

examined for improved screen performance

at the station involved major demolition and

excavation, with costs exceeding one mil-

lion dollars. Thats not what was wanted.

We were looking for a solution that was

cost-effective, Griffi th says. And some-

thing that would fi t into our narrow existing

channel.

The system selected, Screentec, from

Aqualitec Corp., is an automated vertical-

bar screen system designed specifi cally

for narrow- and deep-channel lift stations,

headworks, wet wells and manholes. The

screen has 1/2" openings, signifi cantly

smaller than Sun Citys prior 2" coarse

screen. All wastewater fl ow is diverted

through the system, then back out again.

The system effectively removes 75 percent

of the debris material before it gets to the lift

pumps.

When I fi rst saw a demonstration of the

system, I could see that it would fi t into

the existing Sun City Lift Station channel,

Griffi th says. That meant there would be

no need for demolition or excavation. I also

liked the fact that there were no bottom

bearings, and that it utilized a strap instead

of chains. I would much rather maintain a

strap than I would bearings, chains and the

lubrication required.

Fixed it up

Screentec has no moving parts under

grade level, for easy and safe maintenance

by operational staff, and minimal mainte-

nance costs. An automatic rake system

puts it into a screw conveyor which then

conveys it into a 20-cubic-yard dumpster.

The debris from the lift station fi lls one

dumpster weekly.

The more we can screen out up-

stream at the lift station, the less we have

to deal with at the wastewater treatment

facility, Griffi th says. We stopped a lot

of that material from meandering through

the plant and ultimately taking out equip-

ment. We also protected the pumps at

the lift station, keeping any heavy debris

from getting through. Every time a pump

gets clog up it causes a wearing issue.

As a fi nal note, as an added benefi t,

because of the greatly reduced debris

fl owing through the lift station pumps,

EPCOR believes it can now downsize to

much smaller 135 horsepower pumps.

Automobiles dont need constant mainte-

nance today the way they did, say, 30 years

ago, and the same expectation is found

today in industry. Reliable systems keep

maintenance to a minimum and output to

plan.

In this regard, choosing cooling systems

in the food & beverage industry is governed

by several factors.

For one, any heat-transfer fluid used

within a system must have low toxicity, and

ensure product as well as process-plant

employee and customer safety. Produc-

tivity-wise, poor-quality heat-transfer fluids

cause regular maintenance, leaks and even

system failures.

Microbrewery Lindesnes Brygghus was

established in Lindesnes, Norway in 2011,

selling beers golden, dark and bitter, at

more than one hundred locations. Brew-

ery production and storage is all about

temperature control and a brewery needs

effective and reliable cooling and refrigera-

tion to ensure product safety and longevity.

Heat transfer fluids are a vital part of these

systems.

As a market newcomer, Lindesnes Bryg-

ghus needed confidence it could supply on

time and at capacity, while ensuring quality

and value against overhead. They required

a cooling system that would last and pay

return on investment.

Again, in this regard, when it comes to

heat-transfer fluids, glycol-based fluids are

not particularly corrosive in concentrate

form. But once mixed with water, corrosion,

bacterial growth and scaling can become

an issue. The cooling systems life span is

directly dependent on fluid quality.

On the other hand, using an inhibited

glycol mixed with water of sufficient quality

can improve the reliability and effectiveness

of systems.

Behind the beer

Lindesnes Brygghus engaged with En-

ergy Rent AS, specializing in refrigeration

and process cooling, to find its cooling sys-

tem, and the heat-transfer fluid that would

be used with it.

Kilfrost Cooltrans SustainCTS fluid is

a 1,3-propylene glycol-based concen-

trate fluid (Bio-PDO) manufactured from

corn-sugar, a more sustainable choice

than petroleum-derived 1,2-propanediol

(mono propylene glycol). As the heat

transfer fluid is used in an indirect cooling

process, with potential risk of contact with

beverages, it is important that the fluid is

non-toxic, non-hazardous and free from

carcinogenic, mutagenic and reprotoxic

(CMR) additives.

Bio-PDOTM-based heat-transfer fluids

offer specific performance advantages over

petroleum-derived propylene glycol-based

transfer fluid. With the same level of freeze

protection, viscosity is 33 percent lower

viscosity at -20 degrees C, which means an

improved low-temperature viscosity profile

that translates into improved hydraulic

performance and lower system pressure

drops.


Food & beverage

Cooling-system longevity often governed by heat-transfer fluid choiceNorwegian microbrewery one example of needs general to food & beverage

By Dr. Phil Gray

Using poor-quality heat-transfer fluids is problematic. The author says mixing quality water with inhibited glycol deliv-ers greater reliability and effectiveness.

Write In 112


For example, a 40 percent v/v solution

(solute concentration expressed in vol-

ume/volume percent) of mono-propylene

glycol-based fluid requires up to 2.4 times

more pumping energy than a 40 percent

v/v solution of Cooltrans SustainCTS at -10

degrees C.

Besides improved low-temperature

hydraulics, an inhibited glycol also provides

significantly higher thermal stability, being

up to four times more resistant to oxida-

tive degradation than standard propylene

glycol-based fluid.

The impact poor-quality fluids have on

cooling systems shouldnt be underestimat-

ed, says Morten Magnusson, managing

director, Energy Rent. To give customers

confidence in our systems, high-quality

fluids are specified.

Specs and standards

An international standard created by the

American Society for Testing and Materials,

or ASTM International, for corrosion testing,

known as the ASTM D1384-05, gives a

good indication of the corrosion protection

and resistance to degradation that a heat

transfer fluid offers.

A heat transfer fluid that meets ASTM-

D1384-05 corrosion-test standards maxi-

mizes equipment longevity and minimizes

otherwise unnecessary shutdowns and

repairs.

Use of glycol in manufacture of heat

transfer fluids will help minimize carbon

footprint and greenhouse gas emissions in

industries using cooling.

The manufacture of corn sugar-derived

glycol (bio-PDO) uses up to 40 percent less

energy when compared to standard propyl-

ene glycol. Further reductions are also pos-

sible due to the performance advantages

that the bio-PDO offers as a heat-transfer

fluid in the end application.

scientists found they could easily grow

high-value strains of oil-rich algae while

simultaneously removing more than 90

percent of nitrates and more than 50 per-

cent of phosphorous from wastewater.

The researchers conducted experi-

ments at a wastewater treatment plant

in Texas using 12 open tanks that were

continuously supplied with fi ltered waste-

water from the plant's clarifi ers, which

remove suspended solids from sewage.

A range of environments were tested

in each tank. Some were monocultures

of oil-rich algal strains, while others

contained mixed cultures. Some tanks

contained fi sh that preyed upon algae-

eating zooplankton.

Earlier research had suggested that

a variety of algal species might perform

better in open tanks and that fi sh might

prevent yields being affected by algae-

eating zooplankton, explained study

co-author Evan Siemann, a professor of

biosciences at Rice University.

However, this study showed prolifi c

algal growth in all 12 tanks. Monocultures

were not invaded by other algal species,

and the presence of fi sh did not affect

any variables. Our results are likely to

be very encouraging to algae producers

because the case they would prefer

monocultures with no fi sh and no cross-

contamination was the case where we

saw optimal performance, Siemann said.

ley Griffin in Canberra, Australia.

At a cost of A$11 million ($8.3 billion),

the cutting-edge stormwater system is

the first of its kind in Canberra.

Launched by the Minister for the En-

vironment Simon Corbell on Friday April

10, the Inner North Reticulation Network

will recycle and clean stormwater used

in public spaces, providing up to 500

megaliters of stormwater annually for this

purpose and replacing the high-quality

drinking water previously used.

Corbell commented: This is a prime

example of water sensitive urban design

that will improve water quality in Lake

Burley Griffin, help the city adapt to

climate change, and provide recreational

facilities in the form of wetlands and

green ovals. He added: Such infra-

structure slows stormwater runoff, help-

ing to reduce peak flows during storms.

It is expected to reduce sediment and

nutrients in our waterways by over 50%,

thus contributing to better water quality.

Stormwater runoff that ends up in Can-

berra's lakes includes pollutants such as

nitrogen and phosphorous, which cause

algal blooms.

The stormwater will be captured via

newly constructed wetlands at Dickson,

Lyneham and Flemington Ponds, which

are wildlife habitats as well as recre-

ational spaces.

Extended Range of Diaphragm Valves

Originally, this specially sealed valve

version was developed from the GEM

nominal sizes DN 8 to DN 50 and has

an additional seal provided by silicone

O-rings that seal the interior of the bonnet housing from the out-

side. This prevents, among other things, lubricant that is normally

used for lubricating the spindle from leaking when autoclaving. It

also prevents moisture and dirt from entering the bonnet interior.

The GEM 673P9 diaphragm valve is autoclave-capable and
