Reverse osmosis is a type of filtration method used to separate dissolved solutes from water. It is a process of movement of solvent through a semipermeable membrane from the solution to the pure solvent by applying excess pressure on the solution side. Reverse osmosis is most commonly known for its use in drinking water purification, particularly with regard to removing salt and other effluent materials from water molecules. The process induces pressure on the semipermeable membrane or osmotic membrane, which is defined as osmotic pressure. The method of applying pressure in the opposite direction to reverse the flow direction is described as reverse osmosis.

The reverse osmosis process is opposite to the natural osmosis process, wherein a concentrated solution passes through a membrane in a direction opposite to the natural osmosis process, due to external pressure, which is higher than the osmotic pressure. Reverse osmosis technology removes all the contaminants from the water, making it fit for use.

Some key points to note about reverse osmosis are:

• Reverse osmosis is a membrane treatment process primarily used to separate dissolved solutes from water.
• It is a type of process which is opposite of the osmosis principle.
• Reverse osmosis is most commonly known for its use in drinking water purification, particularly with regard to removing salt and other effluent materials from water molecules.
• The process induces pressure on the semipermeable membrane or osmotic membrane, which is defined as osmotic pressure.
• The method of applying pressure in the opposite direction to reverse the flow direction is described as reverse osmosis.
• Reverse osmosis technology removes all the contaminants from the water, making it fit for use.
