Additional Information

Additional Information

 N/A The CPA5, CPA6 and CPA7 membranes are available in the LD variant wherein low differential LD Technology® is used to minimize colloidal fouling when used with conventional pre-treatment equipment. These membranes offer consistently low feed pressures and longer intervals between cleanings.

Additionally, the CPA5 and CPA6 membranes are available in the MAX variant which have a 440 ft² (40.9 m²) active membrane surface area. The increased membrane area can reduce capital costs by requiring fewer pressure vessels and less floor space.
