Description
The CPA6-LD is the fifth generation CPA brine RO membrane and has the best rejection of all its predecessors at 99.8%. This 400 sq. ft membrane operates at a higher feed pressure than the CPA5-LD, but has the highest rejection in the CPA family.
CPA6-LD membranes are engineered with Low Differential Pressure LDTM Technology designed to minimize colloid fouling. They have a membrane area of 37.0 m2 (400 ft2). Using CPA6-LD results in cost savings while still achieving high rejection from the membranes.
The CPA6-MAX has the same high rejection membrane as the CPA6-LD, but with a 10% increase in membrane area at 440 sq.ft.
CPA6 MAX is the preferred choice for feed waters with low turbidity and silt density index, such as saline well waters.
CPA6-LD and CPA6-MAX membranes are only available in 8.0 inch diameter.
