17 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 2017 Evoqua Water Technologies LLC Confidential Page 17

26 MEDICAL CENTER COOLING TOWER Project Overview 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 Customer Challenge 95% of all system water TSS were smaller than 5 microns. The ultimate reduction of fouling was a key consideration along with space restrictions Evoqua Water Technologies LLC Confidential Page 26

27 SIDE STREAM FILTRATION SIZING YOUR APPLICATION 5% Side stream Flow = 150 gpm Full Flow = 3,000 gpm Why Side Stream Filtration? Filter sizing: 3-10% of recirculation flow Reduces filter size, energy requirements, water consumption US DOE, FEMP: PNNL-SA October Evoqua Water Technologies LLC Confidential Page 27

28 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 Evoqua Water Technologies LLC Confidential Page 28

It must be treated to be reinjected in the oil formation. Very fine particles must be removed to prevent fouling of the formation. Solution nutshell filtration followed by Vortisand filtration to treat produced water before reinjection. Results Vortisand removes very fine silt and can handle 25 ppm of oil at 180 deg. F. The media is replaced every year.
