CPA (Composite Polyamide) membranes set the standard for RO membranes – over 600 million gallons per
day of pure water are produced by CPA elements for global municipalities and industries. CPA membranes
are available in 4” and 8” diameters.PA membranes are available in 4” and 8” diameters.

LD represents a patented 34 mil thickness feed
spacer that represents low differential pressure
(ΔP), prevents colloidal fouling and increases
effectiveness of membrane cleaning.

MAX represents the technology of maximized
membrane area of 440 ft2 to reduce the number
of elements, thereby saving the cost.

CPA elements Classification

CPA2
High rejection brackish water RO membrane that continues to remain popular as the robust workhorse product in the treatment of brackish waters to produce low TDS permeate

CPA3
High rejection brackish water membrane exhibit high tolerance to feed water suspended solids

CPA5
Provide optimum salt rejection and permeate flows
Provide high salt rejection including silica and nitrates

CPA6
Is the fifth generation membrane that is used for treating highly brackish waters demanding very low permeate TDS.

CPA7
Is the sixth generation CPA high rejection brackish water RO membrane offering the highest salt rejection in the industry.
