reverse osmosis reverse osmosisreverse osmosisn. A process by which a solvent such as water is purified of solutes by being forced through a semipermeable membrane through which the solvent, but not the solutes, can pass.reverse osmosis n (Chemical Engineering) a technique for purifying water, in which pressure is applied to force liquid through a semipermeable membrane in the opposite direction to that in normal osmosis reverse′ osmo′sis n. a process in which pure water is produced by forcing waste or saline water through a semipermeable membrane. ThesaurusNoun | 1. | reverse osmosis - (chemistry) a method of producing pure water; a solvent passes through a semipermeable membrane in a direction opposite to that for natural osmosis when it is subjected to a hydrostatic pressure greater than the osmotic pressurechemical science, chemistry - the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactionsosmosis - (biology, chemistry) diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal |
reverse osmosis
reverse osmosis[ri′vərs äs′mō·səs] (chemical engineering) A technique used in desalination and waste-water treatment; pressure is applied to the surface of a saline (or waste) solution, forcing pure water to pass from the solution through a membrane (hollow fibers of cellulose acetate or nylon) that will not pass sodium or chloride ions. reverse osmosis
re·verse os·mo·sismovement of solvent in the opposite direction from osmosis, that is, pressure filtration of solvent through a semipermeable membrane that will hold back the solutes; commonly replaced by filtration or ultrafiltration when speaking of capillary membranes, as in the renal glomerulus.re·verse os·mo·sis (rē-vĕrs' os-mō'sis) Movement of solvent in the opposite direction from osmosis. reverse osmosisA form of water treatment that removes infectious particles and dissolved ions more effectively than other water purification techniques. Water so purified can be used in hemodialysis.
