Function : : R is a process that separates organic

compounds and inorganic materials from water

through a semipermeable which takes place to forcewater molecules to flow against a net osmostic

pressure. This is accomplished by applying enough

pressure on high concentration side of a

semipermeable membrane to reverse the net

migration of water molecules
