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

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.

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

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.

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!
