Hydranautics CPA5-LD–4040 Reverse Osmosis Membrane 4" x 40"
CPA5-LD-4040 is the fourth generation CPA high rejection brackish water RO 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-4040 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.
