HYDRANAUTICS CPA2 – 4040 MEMBRANE
HYDRANAUTICS CPA2 – 4040 (Composite Polyamide) elements set the standard for RO membrane elements – over 600 million gallons per day of pure water are produced by CPA elements for global municipalities and industries. 4” and 8” configurations available.
The workhorse and industry standard, HYDRANAUTICS CPA2 delivers consistently high performance, day in and day out. When high performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements. CPA membranes provide the highest salt rejection rates available – every element on every order for every customer.

HYDRANAUTICS CPA2 High Rejection Membranes
HYDRANAUTICS CPA2 membranes are used to treat a wide range of highly variable waters as either primary treatment or as pretreatment to reverse osmosis (RO)
Compared to conventional pretreatment, Hydranautics combine benefits of high recovery and low footprint requirement due to its optimized membrane area and novel cleaning regimes.
