What is reverse osmosis class 12

Reverse osmosis may be a special sort of filtration that uses a semi-permeable, porous membrane, that permits only pure water to undergo it, filtering the larger molecules or impurities. Reverse osmosis occurs when pressure is applied to the answer on the side of the membrane that contains the lower solvent concentration. The pressure forces the solvent to be due a neighborhood of low concentration to at least one of high concentration.
