CPA3-8040

CPA3 is the third generation CPA high rejection saltwater RO membrane introduced in the late 1990s. With a 99.7% rejection rate, this membrane is an upgrade to CPA2 with 10% more membrane area (400 square feet). This required less pressure vessels and less floor space, resulting in lower capital costs.

CPA3 membranes also feature a thicker (34 mil) feed spacer that exhibits a higher tolerance for suspended solids in the feedwater.

The CPA3 membrane is available in 8.0 inch diameters.
