Lewatit® Ion Exchange Resins
We are a leading global supplier of ion-exchange resins
For over 80 years, LANXESS has been shaping water treatment and liquid purification with innovative Lewatit® and Bayoxide® solutions, global expertise, and dedicated customer support.
Benefits
✓ Comprehensive Lewatit® and Bayoxide® product portfolio
✓ Technical expertise across hundreds of applications
Our ion exchange resins have proven themselves in various processes in the chemical industry, for example as catalysts or in chloralkali electrolysis, but also in the treatment of process and waste water.
Food grade ion exchange resins are used in food and beverage refining, including chromato-graphic separation. Our product portfolio, technical expertise, and global reach allow for solutions of most complex food processes.
Lewatit® resins are contained in filter cartridge systems with which soft drinking water can be produced quickly and conveniently. Our products are also used in numerous household appliances to prevent limescale deposits.
Selective ion exchange resins from LANXESS are used in the treatment of mining liquids and in metal extraction, purification and recovery. Our products offer the possibility of selectively binding specific metal ions.
In the treatment of drinking water, wastewater and waste disposal our ion exchange resins and iron oxide adsorbers benefit from their unique ability to selectively bind ions. Even groundwater can be treated efficiently.
Water is an indispensable auxiliary material in the production of paper and pulp. In order for this complex process to function reliably and produce high-quality paper of consistent quality, the water used must meet high standards.
Our Lewatit® ion exchange resins and adsorbers are widely applied in bioprocessing and pharmaceutical operations for capture, purification and chromatography of various biomolecules.
Water-steam cycles are the heart of all thermal power plants that generate electricity from fossil or nuclear fuels. Lewatit® ion exchange resins are used in power plants among others to demineralize the cooling and boiler feed water.
We offer specific ion exchange resins for ultra-pure water which are manufactured to meet the precise needs of the electronics and semiconductor industry for wafer and microchip production.
