In response to demand for a less cumbersome and costly way to treat seawater for production of drinking water and industrial process water, GE Osmonics, of Minnetonka, Minn., has engineered the new Seasoft™ membrane elements. Utilizing nanofiltration elements as a pre-treatment step reduces the hardness of seawater by more than 95 percent. This hardness reduction enables reverse osmosis plants to operate at lower pressures and higher recoveries.
