KC-ULP4040 Low-Pressure RO Membrane
KC-ULP4040 is an ultra-low pressure reverse osmosis membrane element developed for small to medium-sized RO systems treating low-salinity water. Based on aromatic polyamide technology, it provides stable water production and reliable salt rejection under reduced operating pressure.
Designed for feed water with TDS up to 2,000 mg/L, KC-ULP4040 helps improve system energy efficiency while maintaining consistent water quality. It is widely used in municipal, commercial, and industrial water treatment applications where compact system design and reliable operation are important.
