CPA5-LD is the fourth generation CPA high rejection brackish water reverse osmosis membrane. This 400 sq. ft. membrane with 99.7% rejection was an upgrade to the CPA3 reverse osmosis membrane as it is designed with Low Differential Pressure LDTM. It offers the improved rejection of all ions including silica and nitrates. CPA5-LD reverse osmosis membranes use a patented 34 mil thickness feed spacer that increases effectiveness of membrane cleaning.

As a result, the CPA5-LD reverse osmosis membrane does not need to be cleaned frequently – thus reducing treatment cost – while offering extreme durability and consistent performance.

CPA5-MAX reverse osmosis membranes have 440 square feet of membrane area and are well suited for polishing RO and low fouling applications. This increased membrane area can reduce capital costs by requiring fewer pressure vessels and less floor space.

CPA5-LD reverse osmosis membrane is available in diameters of 4.0 and 8.0 inches and the CPA5-MAX membrane is available in 8.0 inch diameter.
