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 thenatural osmotic pressure is applied on the high concentration side ofthe membrane, forcing the water to travel through the membrane fromthe higher TDS to lower TDS chamber, thus ‘reversing’ the naturaltendency of water flow.
