LANXESS is a major global solution provider for liquid purification, with a leading position in ion exchange resins (IX) and a strong commitment to its reverse osmosis (RO) membrane business. We have 80 years of experience in water treatment and purification applications. This knowledge is essential for complex combined processes, which are requested to reuse or recycle water in minimal liquid discharge (MLD) processes. The Lewabrane® product line includes elements for all the main RO applications, including desalinating seawater, brackish water, and low-salinity water. Leading fields of application include the production of drinking water, but also the treatment of process water and wastewater. All Lewabrane® products are compliant with NSF/ANSI Standard 61. In 2018, LANXESS has entered into an agency agreement with French company Polymem for the distribution of Polymem's Gigamem ultrafiltration (UF) modules range featuring Neophil hollow fiber membranes worldwide. With the intuitive design software LewaPlus® LANXESS offers a comprehensive tool for the planning and designing of industrial water treatment systems.
