Membrane Elements - 21728 Brackish Water Reverse Osmosis Membrane Elements

CPA

High Rejection Membrane

CPA (Composite Polyamide) elements set the standard for RO membrane elements – over 600 million gallons per day of pure water are produced by CPA elements for global municipalities and industries. 4” and 8” configurations available. Advantages • 99.7% nominal rejection • High TOC, silica and hardness rejection Applications • Desalting of well waters – municipal drinking water • Reducing TDS prior to ion exchange • Boiler make-up water CPA2, CPA3, CPA3-LD, CPA5-LD • Ultrapure water for semi-conductor manufacture Product Offering*

ESPA

®

Ultra Low Pressure Membrane

ESPA
® (Energy Saving Polyamide) elements achieve high flux/lower pressure without compromising standards for high rejection. Since its introduction in the late 1990s, the ESPA Advantages
® membrane has gained wide acceptance in the water treatment industry due to the significant operational cost savings associated with their use. 4” and 8” configurations available. • Up to 99.6% nominal rejection • Lower pressure for lower CAPEX/OPEX Applications • Municipal potable and wastewater plants • Bottling operations ESPAB (high boron rejection), ESPAB+, ESPA1, ESPA2 (8” and 16”), ESPA2+, ESPA2-LD, ESPA4 • Light industrial Product Offering*

LFC

®

Low Fouling Membranes

Advantages LFC
® (Low Fouling Composite) elements combine neutral surface charge and hydrophilicity, providing significant reduction in fouling rates and increasing membrane efficiency by restoring nominal performance after cleaning. • 99.7% nominal rejection • Low fouling membrane chemistry reduces or eliminates pre-treatment • LD technology increases brine spacer thickness for reduced differential pressures • Lower cleaning frequency and costs Applications • Municipal/Industrial surface and wastewaters LFC3-LD (Low Differential) • Difficult feedwaters requiring significant pretreatment Product Offering*
