Hydranautics – CPA membranes

Hydranautics – CPA High Rejection Membranes

Hydranautics membranes are used to treat a wide range of highly variable waters as either primary treatment or as pretreatment to reverse osmosis (RO) and nanofiltration (NF).

Compared to conventional pretreatment, Hydranautics combine benefits of high recovery and low footprint requirement due to its optimized membrane area and novel cleaning regimes.

CPA (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.
