Strong technologies for clean water

LANXESS is one of the world’s foremost suppliers of products for treating water and other liquid media. We have more than 80 years of experience in water treatment and are a leader in the development and production of ion exchange resins and iron oxide adsorbers. Furthermore, we produce reverse osmosis membrane elements. We operate production facilities at our sites in Leverkusen and Bitterfeld, Germany, and in Jhagadia, India.


We take purity to a new level

With Lewatit® ion exchange resins and the new Lewabrane® membrane elements for reverse osmosis, we offer our customers two premium, perfectly attuned technologies. While membrane technology is very cost-efficient for water with a high salt content, only ion exchange resins can purify water with low salt concentrations to the point where merely trace amounts remain. Our high-performance products are used in numerous industries. Leading fields of application include the generation and treatment of drinking water, but also the treatment of process water, other industrial water, and wastewater. Bayoxide® E adsorbers reliably remove arsenic, for example, from drinking water and wastewater.

We also offer our LewaPlus® design software, a free tool for planning and designing water treatment systems that incorporates reverse osmosis (RO), ion exchange resins (IX) and ultrafiltration (UF).

In addition we have developed a new normalization software for analyzing Reverse Osmosis (RO) membrane processes called PerforMem™.  By using the software, the reasons for membrane processes experiencing a loss in flow or rejection performance can be analyzed more accurately, and easily.
