Drinking water production - desalination and ultrafiltration

Reverse osmosis (RO) is for water desalination and treatment of highly polluted industrial wastewaters. Behind this technology which remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane.

Osmosis is a naturally and important phenomenon in nature. It is called osmosis when a weaker saline solution will tend to migrate to a strong saline solution. A common example is the absorption of water by plant roots from the soil.

Reverse osmosis water flows from the higher concentrated side (more pollution) to the lower concentrated side (less pollution) to provide clean drinking water. The output after this phenomenon is on the hand clean water (permeate) and on the other hand the left over contaminated water (waste/brine).

While Osmosis appear naturally without additional energy, for reverse osmosis is further energy necessary for the saline solution. A reverse osmosis membrane is used for this where water molecules but not the majority of dissolved salts, bacteria and other components passage.
It works by using a high pressure pump on the salt side in order to force the water through the RO membrane where approximately 95-99% of the salts not pass through.

Reverse osmosis membrane refuse contaminants based on size and charge. RO can remove dissolved ions as for example: Arsenic, Antimony, Aluminum, Barium, Chloride, Fluoride, Iron, Nitrate, Silver, Sodium, Thallium, Radium and select pesticides such as Endrin, Heptachlor and even particles like asbestos fibers.

But there are also some contaminants that reverse osmosis cannot remove from the water: organic compounds, bacterial microorganisms and methane. Because of that it is important to remove dissolved gases before the RO process.

This means that reverse osmosis membrane alone may not be the one and only solution for complete removal of every kind of pollution.
