CPA3 is the third generation CPA high rejection brackish water RO 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 membranes also have a thicker (34 mil) feed spacer that exhibits higher tolerance to feed water suspended solids.
CPA3 membrane is available in diameters of 8.0 inches
