Principles of Osmosis and Reverse Osmosis

Osmosis is the natural tendency of water with a low concentration of total dissolved solids (TDS) to travel through a semi-permeable membrane into a solution of higher TDS in order to balance the solute levels on both sides of the membrane.

What is reverse osmosis?

Reverse Osmosis is a process in which pressure greater than the natural osmotic pressure is applied on the high concentration side of the membrane, forcing the water to travel through the membrane from the higher TDS to lower TDS chamber, thus ‘reversing’ the natural tendency of water flow.
