Membrane Size: 8"x40"
Low Fouling
DESCRIPTION:
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.
