The CPA7 series are the newest CPA brackish water reverse osmosis membranes offering the highest salt rejection in the industry. These ultra-high rejection reverse osmosis membranes are meant to fulfil your purest water quality requirements.

Where ultra-high purity water is required under difficult water conditions, the CPA7 reverse osmosis membranes supply the best combination of high rejection and high flow capability in a brackish water reverse osmosis element, compared to all commercial brackish water reverse osmosis elementsWhere ultra-high purity water is required under difficult water conditions, the CPA7 reverse osmosis membranes supply the best combination of high rejection and high flow capability in a brackish water reverse osmosis element, compared to all commercial brackish water reverse osmosis elements.

The LD variant of these membranes using LD Technology® are available in 4” (CPA7-LD-4040) and 8” (CPA7-LD) diameters. The CPA7 MAX reverse osmosis membrane has an active membrane surface area of 440 ft2 (40.9 m2) which reduces capital costs by requiring fewer pressure vessels and lesser floor space.
