  • 613L250 reverse osmosis system | Sartorius

    Reverse osmosis uses the tightest possible membrane in liquid separation with water being the only material that can permeate the membrane. It is generally used to produce potable, ultrapure and process water. While nanofiltration permits small ions to pass through while excluding larger ions and most organic components like bacteria and spores.
