奧凱〖反滲透設備 〗概述; Okay reverse osmosis water treatment equipment ( inverse ) with high selectivity for reverse osmosis membrane element desalination rate can be high up to 99.7%. So the choice of high salt rejection rate, low osmotic pressure, high flux membrane, can be the most salt ions removal from water. Ro ( reverse osmosis ) is a kind of pressure driven by a semipermeable membrane, the selection
