A differentiation was made between the related membrane processes of reverse osmosis (RO) and ultrafiltration (UF). In RO, practically all molecular species except water are retained inside the membrane. This process is associated with small pore or 'tight' membranes and high hydrostatic pressures (500 p.s.i.). 4, record 3, English, - reverse%20osmosis
