The U.S. National Sanitation Foundation (NSF International) has certified that all brackish water Lewabrane membrane elements currently offered by LANXESS are safe for use in the treatment of drinking water.“This quality certificate is necessary for treating drinking water and, with it, we can now access an additional market with strong potential for growth. It confirms the high quality of our products and thus increases customer confidence in our membranes even more,” says Alan Sharpe, head of the RO Membrane Project in the Liquid Purification Technologies (LPT) business unit of LANXESS. Continuing, he explains: “In most countries, compliance with NSF Standard 61 is a basic prerequisite for usage in drinking water applications and therefore a key quality indicator.”In many parts of the world, particularly industrialised countries, drinking water is treated centrally and in large quantities in municipal or regional plants. There are also smaller, decentralised plants in hotels, restaurants, on passenger ships or in remote communities, for example.The primary aim of the NSF Standard 61 is the objective evaluation and limitation of impurities and admixtures that are added to drinking water indirectly due to the products, components and materials used in the treatment process. The NSF standard is designed to protect public health and the environment.
