dws-nijhuis-03gac-wwtp-horstermeer-770pxDutch-based firm Nijhuis Industries joins a research project on the removal of micropollutants, using ozone and activated carbon filter (O3GAC) as additional effluent polishing of municipal waste water. The Delft University of Technology will set-up laboratory testing to investigate the O3GAC-technology. Nijhuis Industries will be building a modular demonstration pilot once the research is completed.

The O3GAC is a triple barrier, based on oxidation, adsorption and biological activated filtration. The ozone will break the micropollutants into smaller pieces.

Then absorption and biological conversion will take place inside the activated carbon filter and emissions of by-products will be reduced.

The demonstration pilot will be located at waste water treatment plant Horstermeer, near Amsterdam, the Netherlands (on top photo). It will have a flowrate of ten cubic meters of wastewater per hour.

Application aboard
The pilot will also be trialled at a sewage treatment plant of Aquafin in Belgium and at a further sewage treatment plant of Wasser Verband Eifel Rur in Germany.

The purpose of changing the location of the O3GAC application is to investigate whether the application can be installed not only in the Netherlands, but in Europe and possibly worldwide.

Other Dutch parties involved in the research project are consultancy firm Witteveen+Bos, foundation for applied water research STOWA and Amsterdam water utility Waternet.
