REVERSE OSMOSIS High pressure liquid solution water is extracted by using asymmetric membranes. But they impede dissolved salts and organic molecules passage. Operation pressure varies between 14 and 70 bar.
Basics: It is a process in which certain materials are able to exchange water ions. The materials are polymers (macromolecules), with active terminal functional groups, where exchange reaction produces.
The light is an electromagnetic radiation or bright energy traveling in a wave shape. Ultraviolet energy is found in the electromagnetic spectrum between visible light and X rays and the best way to describe it is like an invisible radiation.
