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).

Growth and entrepreneurial responsibility go hand in hand.

Corporate Responsibility is a prerequisite to being able to operate successfully in the future and create value for all stakeholders. Given this awareness, sustainability is a key success factor that is at the heart of LANXESS’s corporate culture. For us, actively demonstrating Corporate Responsibility involves knowing and evaluating the impact of our actions – whether positive or negative – and maintaining a dialogue with stakeholders that enables us to satisfy their expectations to the best of our ability.

Corporate Responsibility is an integral part of LANXESS’s strategy. With it we aim to bring in line economic, ecological and social considerations, while implementing targeted CR initiatives that cater to the expectations and needs of our stakeholders wherever we operate. This helps ensure the sustainability of our clients and society. 

Under the umbrella of Corporate Responsibility LANXESS interlinks its company’s initiatives in the field of Corporate Governance, Sustainability and Corporate Citizenship, aiming to harmonize economic, ecological and social needs in the long term.
