Reverse Osmosis System

Reverse Osmosis

Reverse Osmosis is a water purification technology that uses a semi-permeable membrane to dissolve a solution of water and other components such as salts, separating them. Larger ions, molecules, and particles are removed from drinking water.

In order to achieve reverse osmosis, a pressure capable of overcoming the “osmic” pressure is
applied, which is what maintains water as a solvent element, combined with soluble particles.

Reverse Osmosis can remove many types of suspended elements in water, including bacteria, and is used both in industrial processes and for the production of drinking water.

Reverse Osmosis Membranes

As a result the solution is retained on the pressurized side of the membrane and the pure
solvent passes to the other side of the membrane. To achieve the goal, the membrane must not
allow large ions or molecules to pass through its pores, but must allow smaller components
such as water molecules to pass freely.
