Wastewater contains more and more pharmaceuticals that are difficult to remove in wastewater treatment plants (WWTPs). This issue calls for close collaboration between government, businesses and knowledge institutions. With this backdrop, KWR Watercycle Research Institute, Limburg Waterboard Company (WBL), Limburg Water Distribution Company (WML) and PureBlue Water have, within the TKI Water Technology programme, carried out a project aimed at removing pharmaceuticals using a two-step process: ion exchange followed by advanced oxidation. After having been tested in principle in a laboratory, the method was applied on a large scale in a pilot at the Panheel WWTP. The outcome is that it is indeed technically possible to use this method to effectively remove a broad range of pharmaceuticals from the effluent.
