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 incorporate reverse osmosis (RO) and ion exchange resins (IX).
