KC-SW4021 Compact Seawater RO Membrane
KC-SW4021 is a compact seawater reverse osmosis membrane element developed for space-limited desalination equipment and low-flow seawater treatment systems. Based on aromatic polyamide technology, it delivers reliable salt rejection and stable water production under high-pressure operating conditions.
Designed for feed water with salinity above 10,000 mg/L, KC-SW4021 enables flexible system integration in compact RO equipment while maintaining dependable desalination performance. It is widely used in portable desalination units, marine water treatment systems, and other space-constrained applications.
