FINE FILTRATION INCREASES PROCESS MANUFACTURING EFFICIENCIES

Water Re-use Reduce TSS load of reclaimed water for process makeup Fine filtration can remove particles that buildup and get recycled over time

Reverse Osmosis (RO) - Pretreatment Fine particles causes membrane fouling Silt Density Index (SDI) is used to measure fouling on membranes. SDI above 3 will:

Increase energy costs due to fouling/flow reduction Increase costs on membrane cartridge replacements & labor Increases in CIP frequency & process shutdowns

Fine Filtration can reduce SDI and provide better membrane performance and life

Protecting sensitive equipment Fine filtration will remove particles that can cause fouling and corrosion Reduced corrosion on nozzles, pumps, mechanical seals, compressors

CASE STUDIES


MEDICAL CENTER COOLING TOWER

Installation: 31,800 sq ft Central utility plant Cooling Towers: (4) 1,000 ton Recirculation Rate: 3,000 gpm Filter Solution : 4 Vortisand Classics Year: 2015

Project Overview

95% of all system water TSS were smaller than 5 microns. The ultimate reduction of fouling was a key consideration along with space restrictions.

Customer Challenge


SIDE STREAM FILTRATION SIZING YOUR APPLICATION

Why Side Stream Filtration?

Filter sizing: 3-10% of recirculation flow Reduces filter size, energy requirements, water consumption

US DOE, FEMP: PNNL-SA-91274 October 2012

Full Flow = 3,000 gpm

5% Side stream Flow = 150 gpm


MEDICAL CENTER COOLING TOWER

.RESULTS

After just 60 days of replacing the centrifugal separators with the Vortisand system a 90% removal of particles less than 5 microns was achieved.


PULP & PAPER WELL WATER RO PRETREATMENT

Well water pre-RO treatment for make-up water Client: Pulp & paper Solution Type: Vortisand H2F300 Year of Completion: 2014 Capacity: 300 gpm

Project Overview

TSS removal effecting the systems efficiency levels

Customer Challenge

Laser Particle Analysis Design & engineering Equipment supply Project management Construction & installation by partner Supply of initial reagents and supplies Startup & commissioning Training

Scope of work

Vortisand filters (350 gpm each) were installed at two locations.

Solution

1.5M particles at the inlet, test results show 12,000 particles at the outlet (99% removal). It is important to note that all particles weresmaller than 5 microns.

OIL & GAS PRODUCED WATER TREATMENT

Water treatment for reinjection Solution Type: 8 Vortisand Classic 36-in Year of Completion: 2011 & 2015 Capacity: 600 gpm

Project Overview

Produced water can no longer be discharged to the environment. It must be treated to be reinjected in the oil formation. Very fine particlesmust be removed to prevent fouling of the formation.

Customer Challenge

Laser Particle Analysis Design & engineering Equipment supply Project management Construction & installation by partner Supply of initial reagents and supplies Startup & commissioning Training

Scope of work

nutshell filtration followed by Vortisand filtration to treat produced water before reinjection.

Solution

Vortisand removes very fine silt and can handle 25 ppm of oil at 180 deg. F. The media is replaced every year.

Results


LIMITATIONS OF THE TECHNOLOGY

HVAC/Cooling & Heating LoopsThese applications are much more forgiving.

Process Applications Turbidity (NTU) is also an important parameter to consider when choosing the right solution.

SUMMARY

Clear does not equal clean

Removal by weight provides inefficient filtration

Submicron high efficiency filtration matters

The side effects of not filtering your process water can become very costly

An efficient process can help improve your organizations bottom line!
