8040 RO Membrane

8040 Membrane  is a Reverse osmosis (RO) membrane used in water purification process, these are semi permeable membranes which separate ions, unwanted molecules and larger particles from processed water. Permeate water is forced through these membranes with the use of pressure built in with the help of a pumping system.
