Reverse Osmosis is water filtration process using membrane technology. Reverse Osmosis filter system process is more effective and cost saving. It enables to purify 99% of impurities like salt, ions and other microns dissolved in water.Natural Osmosis is a process where water flows from low solute concentration to high solute concentration, and results in developing osmotic pressure that is used to stop the water from flowing through the membrane, in order to create balance. For actual water purification treatment, Reverse Osmosis process is adopted by applying external pressure that exceeds osmotic pressure, the water flow will be reversed and thus water flow from high concentration to lower through the synthetic semi-permeable membrane which does not allow impurities or inorganic solids and particles larger than .001 microns to pass through it.Based on the quality of filter and membrane, all the contaminants including bacteria, viruses, parasites, heavy metals, inorganic chemicals, pesticides and algae will get removed. These impurities and contaminates are flushed down the drain.

Seawater is desalinated to produce water suitable for human consumption or irrigation.The increasing population as well as unavailability of abundant Fresh Water has forced mankind to make sweet water from salty sea water. 

The leading process for desalination in terms of installed capacity and yearly growth is reverse osmosis (RO). The RO membrane processes use semipermeable membranes and applied pressure (on the membrane feed side) to preferentially induce water permeation through the membrane while rejecting salts.
