Description
Hydranautics – CPA High Rejection Membranes
Hydranautics CPA (Composite Polyamide) membranes are engineered to treat a wide variety of highly variable water sources, serving as either primary treatment or as pretreatment for reverse osmosis (RO) and nanofiltration (NF) systems. These membranes are particularly effective in demanding applications, offering high recovery rates and low footprint requirements due to their optimized membrane area and innovative cleaning regimes.
Hydranautics CPA membranes are a standard in RO technology, with over 600 million gallons per day of pure water being produced globally by these elements, serving municipalities and industries.
