Hydranautics CPA (Composite Polyamide)

Setting the industry standard for the highest salt rejection rates

Ultrapure water is essential in several industrial applications. CPA RO membranes are regarded as the industry standard for all critical high purity applications – from pharmaceutical to power industry.

CPA lines of spiral-wound RO membranes are available in a variety of sizes and deliver unmatched performance with the highest salt rejection rates for brackish water applications. High throughput, efficiency and cost-effectiveness make CPA membranes the best high-rejection brackish water RO membranes in the industry.

Because of its exceptionally high salt rejection, CPA membranes are used in power generation, pharmaceutical, electronics and semiconductor industry.

• CPA3: CPA3 high rejection brackish water membrane exhibits high tolerance to feed water suspended solids.
• CPA5: CPA5 membranes provide optimum salt rejection and permeate flows. They are chosen when lower permeate TDS and lower feed pressures are needed. CPA5 membranes offer highest energy efficiency at lowest costs and provide high salt rejection including silica and nitrates.
• CPA6: CPA6 is the fifth generation membrane that is used for treating highly brackish waters demanding very low permeate TDS.
• CPA7: CPA7 is the sixth generation CPA high rejection brackish water RO membrane offering the highest salt rejection in the industry.
