Membrane elements desalinate seawater and brackish water

The Lewabrane Series membranes (photo) use reverse osmosis to desalinate seawater and brackish water. Water is forced through the semi-permeable membrane at high pressure, to remove salts and other unwanted substances, including borates, nitrates, arsenates and silicates. Depending on the intensity of use, these spiral-wound, thin-film composite membranes can last for several years, says the company. The Lewabrane RO membrane elements for applications with standard pressure (15.5-bars test pressure) are offered in two types: HR (high rejection) and HF (high flow). The HR-type elements are designed to provide extremely low salt passage under normal operating conditions (yielding >99.7% salt rejection, and optimal removal of other target ions, measured at standard test conditions). The HF-type elements allow for increased water productivity coupled with a slight increase in permeate salinity. — Lanxess AG, Cologne, Germany
