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 at a lower cost. Andijk III has a capacity of 5,000 m3 per hour or 120,000 m3 a day.
SIX® removes water turbidity (dissolved organic substances, nitrate and sulphate). SIX® also ensures that the ceramic membranes are not contaminated too quickly. 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 last longer and are more reliable than polymer membranes. CeraMac® is the first design that can compete with polymer membranes in terms of price.
The treated water may still contain a quantity of hazardous substances, such as pesticides, viruses or drug residues. That is why advanced oxidation is used after the CeraMac® process, which uses a combination of UV and hydrogen peroxide to render these substances harmlessly. Since the clarity of water has increased thanks to SIX® and CeraMac®, considerably less energy is required for UV treatment. Finally, an active carbon filter removes the remaining substances from the water, making it fit for consumption.
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 succeeded through good planning, smart logistics and joint cooperation. 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, we can ensure a robust and sustainable water treatment. This video provides an in-depth view of the final design and treatment process for safe, superb drinking water.
Andijk III Showcase
On May 8 2014 PWNT launched the Andijk III project. This took place during an international water conference in Andijk, in the presence of representatives of national and international water industrialists, see press release.
Cindy Wallis-Lage, President Global Water Business at Black & Veatch, qualifies Andijk III as an excellent example of ‘disruptive innovation’: “This is what makes a difference. It takes a journey to make innovation move faster: integration and sharing of knowledge as well as collaboration. Together we can achieve so much.”
“Water is complex, but the goal is simple”, says IWA President Glen Daigger, “We can provide people with reliable water. Therefore we must change what we do, like PWNT has done here. Andijk III is a major example.”
Dr. Shane Snyder, Professor chemical and environmental engineering at the University of Arizona: “More companies should consider using this type of technology and scale up, to demonstrate to the world that these technologies are efficient, robust and reliable.”
Andijk III Online Tour
Welcome in Andijk III, world’s most modern drinking water treatment plant. Each day Andijk III produces 120 million liters (or about 32 million gallons) of drinking water.
It is designed to make water treatment more sustainable and more efficient. The treatment requires less maintenance than a conventional water treatment plant, at lower costs.
The installation uses the PWNT’s innovations: SIX® and CeraMac®. In combination with the existing UV-peroxide technology and activated carbon filtration, PWN ensures a robust and sustainable water treatment.
