ACM4 Low Pressure Reverse Osmosis (RO) Polyamide elementsA

The ACM4 membrane offers higher flux than the ACM1 or ACM2 allowing operation at ultra low pressures. The ACM4 will typically operate at feed pressure of 100 - 150 psi (7 - 10 bar). Even at these high flux rates, the ACM4 still averages 99.2% salt rejection.

Due to the high specific flux, these membranes are best suited to applicaitons with relatively low TDS (<3,000 ppm) to achieve balanced flux rates within the system.
