Lanxess’ Ion Exchange Resin For Mobile Water Treatment Unit For Pfas Removal

Wedoany.com Report-Nov 21,  Since May 2024, the Belgian company De Watergroep has been operating the containerised water treatment plant on site. It will be used for at least two years, after which the plan is to switch to alternative water sources with lower PFAS levels. The objective is to permanently reduce the PFAS contamination of drinking water in Flanders to below 50ppt and thus increase the quality of the water.

De Watergroep is the reportedly largest water supply company in Flanders, Belgium. It ensures that 177 municipalities in west and east Flanders, Flemish Brabant and Limburg are supplied with water via a network of more than 34,000km.

“Together with our customer De Watergroup, our Lewatit TP 108 DW ion exchange resin has been installed to remove PFAS from drinking water,” said Bjoern Dinges, LANXESS application technology manager.

“The system meets the latest standards in drinking water treatment technology and achieves outstandingly low levels of PFAS in the filter effluent compared to other technologies. Modular systems for drinking water treatment are also a solution for the treatment of drinking water worldwide.”

The system is installed directly in the drinking water pipe. With a PFAS concentration of 80ppt, the water supplied is still below the limits. To achieve a long service life, pre-filtration is used. The chlorine is removed before the ion exchangers IEX filters and is re-dosed after it has passed through. LANXESS will support the project for two years and continuously record the process and performance data.
