Our R&D team is continuously looking for better and more sustainable water treatment solutions and works in close partnerships with recognized institutions, universities and utilities worldwide. The PWNT Andijk R&D centre is one of the biggest water treatment R&D centres in the world.
Holly Shorney-Darby, Senior Project Manager, serves as a liaison between PWNT research group and the clients at other utilities.
“Because many of the international drinking water companies are facing similar problems as PWN in Andijk, our work is most interesting. PWN and PWNT have worked to advance and implement existing technologies. Our relations find it unique and inspiring that a utility can take this on.”
At PWNT R&D technology research takes place, ranging from classical to the most innovative water treatment techniques. Our technology researchers are responsible for the design and execution of a variety of experiments at the R&D lab. Currently the focus is on ion exchange, coagulation, advanced oxidation and membrane filtration. All in the context of integrated treatment approach both for drinking water or reuse.
PWNT developed application of suspended ion exchange in our facilities. One of the main projects is to modelize the SIX® process, by looking at the kinetics of the resin, with respect to DOC and nitrate removal. These models are essential to scale up. To mitigate waste streams we explore the possibilities of dynamic vapour recompression. Technologies such as membrane filtration, electro dialysis and eutectic freezing are explored to enable reuse of organic matter in a circular economy.

PWNT developed the CeraMac®, a large vessel with ceramic membranes. This development allowed larger scale application of ceramic micro filtration in surface water treatment. In our research programme, PWNT explores the combination of pre-treatment using ion exchange and/or in line coagulation on the performance of the ceramic micro filtration. Flux enhancement, fouling control and resulting water quality are the main points of attention in the research.

R&D Center: one of the largest worldwide
PWNT R&D centre is located in Andijk (The Netherlands). With 1000m2, it offers sufficient space to house several pilots and bench scale equipment. This facility allows us the flexibility to investigate processes in the field of for example ion exchange and membrane filtration. Over the years PWNT R&D centre was involved in the development and full scale implementation of technologies such as ultrafiltration, UV based advanced oxidation, SIX® and CeraMac®.
