en-GB Reverse Osmosis for desalination and water treatment

Reverse osmosis / Nanofiltration

Reverse osmosis / Nanofiltration

Reverse osmosis is a physical process for concentrating substances dissolved in liquids. The natural osmosis process to balance concentrations is reversed by means of pressure. Reverse osmosis is essentially used for the desalination of water using a semi-permeable membrane. In reverse osmosis, a selective separation (concentration) of dissolved substances from a solution is carried out by pressing them under high pressure through a semi-permeable membrane. By using reverse osmosis, viruses, sugars, proteins, pectins or salts can be separated.

Water is a valuable asset, especially in the driest and most impassable regions of our planet

Whether seawater desalination in Sinai or drinking water treatment in humanitarian operations, our FILMTEC™ elements for reverse osmosis and nanofiltration from Dow Water & Process Solutions are used in a wide range of applications worldwide.

FILMTEC™ reverse osmosis

Die FILMTEC™; reverse osmosis elements are divided into the areas of drinking water (TW), brackish water (BW) and seawater (SW).

The drinking water elements are mainly used for the desalination of town water with an already good initial quality.
The brackish water elements are used, for example, in industry for the treatment of water with low to medium salt loads.

The seawater elements are usually used for the desalination of seawater or water streams with high salt load.
