The Andijk III plant in the Netherlands is based on PWNT’s SIX® (Suspended Ion Exchange) and CeraMac® (ceramic membrane filtration process). It produces water of a better quality with lower environmental impact and decreased energy consumption. Andijk III treats a reservoir source water.
SIX® removes water dissolved organic carbon, nitrate, and sulphate. The DOC removal is important to help downstream processes work more efficiently. The passage through the ceramic membranes is the next phase of the treatment process. All particles larger than 1/10,000th of a millimeter are removed. Ceramic membranes have proven to last longer and be more reliable than polymeric membranes. CeraMac® is the first design that has been shown to successfully compete with polymeric membranes in terms of price, when considering the life cycle of the asset.
The treated water may still contain a quantity of hazardous substances, such as pesticides, viruses or drug residues. That is why advanced oxidation with UV and hydrogen peroxide is used after the CeraMac® process. Because the clarity of water has increased thanks to SIX® and CeraMac®, considerably less energy is required for UV treatment. Finally, an activated carbon filter removes the remaining substances from the water, producing an excellent finished water quality for consumers.
Construction of Andijk III began on 25 January 25, 2012. Two years later, this new treatment facility was up and running. A complex, but great engineering challenge that was, at the time, the first CeraMac® full-scale plant. This video provides a brief, musical overview of some of the construction highlights.
Andijk III uses our latest innovations: SIX® and CeraMac®. Combined with the existing ultra-violet and activated carbon technologies, a robust and sustainable water treatment is achieved. This video provides an in-depth view of the final design and treatment process for safe, superb drinking water.
Andijk III is located at the shore of the IJsselmeer, Western Europe’s largest lake. A bird-eye’s view provides a new perspective on the scale of our treatment plant.
