What is reverse osmosis
Answers
the direction of osmosis can be reversed if a pressure Lodges in the osmotic pressure is applied to the solution side that is now the pure solvent flows out of the solution to the semipermeable membrane this phenomenon is called reverse osmosis and is of great practical utility reverse osmosis is used in dissolution of seawater schematic setup for the process is shown down when pressure more than osmotic pressure is applied pure water is squeezed out of the sea water to the membrane a variety of polymer membranes are available for this purpose the pressure required for the reverse osmosis is quite high a workable porous membrane is a film of cellulose Acetate placed over a suitable support cellulose Acetate is permeable to water but in permeable to impurities and ions present in the sea water these days many countries devaluation pants to meet their portable water requirements
