Hydranautics CPA3


Individual offer for 10+ pcs. Please use our ask form. 

CPA3 is the third generation CPA high rejection brackish reverse osmosis membrane introduced in the late 1990’s. This membrane at 99.7% rejection is an upgrade to the CPA2 with 10% more membrane area (400 square feet). This resulted in reduced capital costs by requiring fewer pressure vessels and less floor space. CPA3 reverse osmosis membranes also have a thicker (31 mil) feed spacer that exhibits higher tolerance to feed water suspended solids.
