Portable RO desalination for drinking water treatment, sea water desalination RO unit

Reverse osmosis is a kind of membrane separation technology developed since the 1980s. It mainly uses the osmosis principle of semi-transparent membrane. A pressure that is called reverse osmosis. The device that is composed of reverse osmosis components is called reverse osmosis device.

1.A semi permeable membrane in a reverse osmosis system only allows certain things to pass through.

2.This membrane passes water easily but also prevents many other contaminants from passing by trapping them.

3.Water is normally on both sides of the membrane, the water on each side has a different concentration of dissolved minerals.

4.The water in the less concentrated solution tries to dilute the more concentrated solution.

5.Water will pass through the membrane from the lower concentration side to the greater concentration side.

6.The osmotic pressure (see diagram) created by the difference in water levels, will counter the diffusion process forming an equilibrium between the two sides.
