Abstract
Under the general term of membrane processes separation methods are included, in which the desalination effect is due to the action of a membrane. Electrodialysis uses ion selective membranes and a direct current as driving force. In all other membrane processes the driving force is a pressure differential. Reverse osmosis makes use of semi-permeable membranes. Hyperfiltration is synonymous with reverse osmosis. Ultrafiltration differs from reverse osmosis in the characteristics of the membranes used, in the size of the separated particles and necessity of lower pressures. In a newer term these processes are also named as membrane filtration. Piezodialysis is a pressure driven process which uses ion exchange membranes.
