Liquid Purification Technologies

Two ways, one goal – Clean water

The Liquid Purification Technologies business unit (LPT) is one of the world's foremost suppliers of products for treating water and other liquid media. We hold a leading position in the development and production of ion exchange resins and are very active in our new business line for reverse osmosis membrane elements. We have production sites at our locations 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® RO membrane elements, we offer our customers not one, but two premium technologies that are perfectly adapted to one another. 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 only trace amounts remain.

Our high-performance products are used in numerous industries to treat and purify water and other liquid media. The most well-known and significant field of application is the treatment of industrial process water. Energy suppliers use our products in the production of boiler feed water and steam to avoid scale and corrosion. This results in a significant increase in the efficiency, operational reliability and service life of the power plants.
