A reverse osmosis desalination system is designed to overcome the existing osmotic pressure of a sea or ocean water using a pump and semi permeable membranes. The osmotic pressure of ocean water is approximately 300 psi on average. By boosting the pressure of that seawater to 2 or 3 times the osmotic pressure against a semi permeable membrane, there is significant positive pressure to filter out dissolved salts as water is driven to permeate the membrane that the salt cannot. At some point, as the seawater is de-watered, the remaining seawater reaches a concentration with an increasing osmotic pressure approaching that of the pressure applied by the pump. In a reverse osmosis desalination system, one feed stream enters the system and 2 exit. One exiting stream is the permeate or product. The other exiting stream is the concentrate or reject. The permeate has passed through the membrane and is relatively salt free. The concentrate is now more concentrated in salt by a factor of how much permeate or de-watering occurred. Most all of the salt from the feed water is now found in the concentrate water. Ocean water is continuously feed to the equipment at a rate equal to that of the permeate and reject combined. Dividing the product flow out by that of the raw feed flow in is referred to as the recovery rate. Dow membrane customers are primarily original equipment manufacturers of water treatment systems, engineering companies that specialize in the design and installation of water treatment systems, water service companies that operate water treatment systems for industrial and other water end users, and public and private water utilities. Dow membranes customers serve a wide range of end users including power generation and semiconductor plants, chemical and process industries, municipalities, and other commercial and consumer customers. Dow Water & Process Solutions is a leading purification and separation technology supplier, offering customers advanced membrane technologies that make water safer, cleaner and more available; food better; and pharmaceuticals more effective. In doing so, they enable the success and well-being of both customers and the millions of people they use the Dow membrane and the Filmtec brand. </p><strong>About the Author:</strong><br /><a rel="nofollow" href="http://www.pure-aqua.com/desalination.html">desalination</a> <a rel="nofollow" href="http://www.pure-aqua.com/desalination.html">water desalination</a> <a rel="nofollow" href="http://www.pure-aqua.com/water-treatment-systems.html">water treatment systems</a> Contact Us:- Pure Aqua, Inc. 2230 South Huron Drive Santa Ana, CA 92704 USA Tel: (714) 432-9996 Fax: (714) 432-9898 <p> Article Source: <a href='http://www.articleseen.com/Article_Desalination-systems-refers-reverse-osmosis-process-being-used-to-desalt-water_81890.aspx'> http://www.articleseen.com/Article_Desalination systems refers reverse osmosis process being used to desalt water_81890.aspx</a></p>
