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. We operate production facilities at our sites in Leverkusen and Bitterfeld, Germany, and in Jhagadia, India.

We take purity to a new level

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 of our Lewatit® ion exchange resins include the generation and treatment of drinking water, the removal of per- and polyfluoroalkyl substances (PFAS), but also the treatment of process water, other industrial water, and wastewater.

In addition to our conventional ion exchange resins we offer Lewatit® Scopeblue resins which are used primarily for the partial softening of drinking water and have a carbon footprint that is up to 67 percent smaller than conventional types and consist of more than 90 percent renewable raw materials.

Our Bayoxide® E adsorbers reliably remove arsenic, for example, from drinking water and wastewater.

We also offer our LewaPlus® design software, a free tool used for modelling and dimensioning of diverse ion exchange systems utilizing Lewatit® resins.
