An efficient technology from LANXESS for treating water is the use of Lewatit ion exchange and specialty adsorber resins. Among other applications, ion exchange resins are used to remove pollutants, such as nickel, nitrate, perchlorate, borate and hydrocarbons from drinking water. During the ion exchange process, contaminated water flows through a container filled with ion exchange resin. It filters the contaminants, binding the ions of the pollutants and replacing them with harmless ions. A variety of resins are used, depending on the pollutant. In the treatment of wastewater, the ion exchange resins remove heavy metals, such as mercury or cadmium. In addition, precious metals, such as copper or platinum, can be filtered out and then used for other purposes. Industrial applications include the treatment of water for industrial processes in power plants. These costly facilities need large volumes of cooling and process water, which have to be demineralised to protect the systems against limescale, for example. The microchip and pharmaceutical industries require water in extremely pure form. Lewatit is used in these industries to produce ultra-pure water, which is a vital manufacturing resource.
