Hydranautics CPA-4040E Membrane

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.
