Hydranautics Water Treatment Consumables , 4040 8040 Brackish Water Ro Membranes
Hydranautics brackish/tap water RO membrane 4040 8040 ESPA1/CPA3/PROC/YQS4
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.
CPA5-LD has minimized biofouling, minimized colloidal fouling and enhanced cleanability. 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.
