  • CPA Series Membranes CPA Series Membranes
    The Hydranautics CPA Product line includes: Hydranautics CPA2 The workhorse and industry standard, CPA2 delivers consistently high performance, day in and day out CPA3 The element with the best combination of productivity and salt rejection available CPA4 For applications where the highest salt rejection is required. High Performance for the highest quality water When high performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements. Over a half-billion gallons per day of pure water are produced by CPA2 for the world's industries, and for municipal supplies around the globe. CPA3 and CPA4 offer even higher salt rejection rates. Semiconductor manufacturers rely on Hydranautics to provide the ultrapure water needed for production of sensitive semiconductor chips. And because of their high TOC, silica and hardness rejection, CPA3 and CPA4 are ideal for producing low-scaling boiler make-up water for power generation applications. CPA membranes ensure reduced maintenance and more efficient power plant operation, while significantly reducing downstream ion exchange costs. CPA membranes provide the highest salt rejection rates available - every element on every order for every customer.
  • LFC Series Membranes LFC Series Membranes
    Hydranautics LFC Series Low Fouling Composite Membranes A new generation of low fouling elements: Hydranautics LFC1 - High rejection and productivity with high flux stability. Hydranautics LFC3 - Hydranautics’ unique hydrophilic chemistry makes this the only true low-fouling membrane in the industry for applications which demand high-efficiency flow and the highest salt rejection. Superior membrane technology is the key to Hydranautics’ innovative LFC (Low Fouling Composite) membrane. LFC membranes offer breakthrough technology in the treatment of difficult feedwaters, municipal wastewater and other challenging feedwaters. Until now, these applications have required significant pretreatment prior to subjecting them to a composite polyamide membrane. Combining the attributes of a neutral surface charge and hydrophilicity, LFC provides significant reduction in fouling rates, increasing membrane efficiency by restoring nominal performance after cleaning. The high performance LFC1 is ideal for municipal and industrial surface and wastewater applications where high rejection is required. New LFC3, ideal for municipal wastewater applications, is the only membrane in the industry that offers low fouling membrane chemistry with high efficiency flow and rejection characteristics. LFC3 offers 50% lower salt passage than the competition.
