WATER DESALINATION BY REVERSE OSMOSIS

• Osmosis is a natural phenomenon by which water flows across a semi-permeable membrane.

• Semi-permeable membrane is selective: It allows water to pass through, while does not allow salts.

• When a membrane separates two water solutions with different salt concentrations, water will flow from the side with the low salt concentration to the side with the high salt concentration
