Desalination

Around the world, reserves of pure drinking water are being depleted. A ready supply of clean water is one of the basic necessities of life. Producing drinking water from the sea is a growing activity all over the world and the Renroc Group is an essential part in desalination plants.

Desalination of seawater is a well-established means of water supply in many countries. It is now feasible, technically and economically, to produce large quantities of water of excellent quality from desalination processes. Membrane processes, mainly Reverse Osmosis (RO), are currently the fastest growing techniques in water desalination. The RO uses dynamic pressure to overcome the osmotic pressure of the salt solution. With RO, salty water is subjected to high pressure and forced through a membrane, which results in the retention of the salt ions.
