When Water Is Passed Through A Semi-Permeable Membrane Under Pressure, All Particles Larger Than 0.001 Micron Are Captured In Layers Of The Membrane Allowing Only The Water Molecules Pass Through The Membrane. The Reverse Osmosis Technology Is Used In Areas Like Healthcare And Scientific Research Where Purity Is Not Just Important But Critical. It Has Now Been Adapted For Use In Industries And Offices To Provide The Same Level Of Purity At Minimal Cost.
