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
