Product Description

Setting the industry standard for the highest salt rejection rates

Ultrapure water is essential in several industrial applications. CPA RO membranes are regarded as the industry standard for all critical high purity applications from pharmaceutical to power industry.

CPA lines of spiral-wound RO membranes are available in a variety of sizes and deliver unmatched performance with the highest salt rejection rates for brackish water applications. High throughput, efficiency and cost-effectiveness make CPA membranes the best high-rejection brackish water RO membranes in the industry.

CPA5-LD is the fourth generation CPA high rejection brackish water RO membrane. This 400 sq. ft. membrane with 99.7% rejection was an upgrade to the CPA3 membrane as it is designed with Low Differential Pressure LDTM. It offers the improved rejection of all ions including silica and nitrates.

CPA5-LD membranes use a patented 34 mil thickness feed spacer that increases effectiveness of membrane cleaning.

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