Closing the water chain by purifying waste water
After purification, waste water is normally only supposed to be discharged. Now that sustainability is becoming more and more important in our society and we are facing a shortage of fresh water, there is a growing interest in the re-use of (waste) water and in closing the water chain. Evides Industriewater can do so much for you.
Effluent as process water Effluent from waste water purification plants can be upgraded to process water. The quality of this water is indeed very diverse, but in most cases it can be used as industrial or agricultural water. It can also serve as a source for upgrading to high-quality deminwater (with a purification facility).
Membrane technology In recent decades, Evides Industriewater has gained a wealth of experience with membrane technology (MF, UF and RO). With this technological knowledge, we are able to design, build and operate effective purification plants that purify effluent very effectively and make it suitable for re-use.
The advantages of recycling waste water The advantages of waste water re-use are obvious: a smaller water footprint and cost savings due to the reduced consumption of drinking water; the re-use of freshwater effluent is much cheaper than the desalination of seawater, has significant environmental benefits and reduces the use of fresh water. That ensures that the water chain can actually be closed.
Applications of waste water re-use Dow Benelux (Terneuzen) has the largest effluent recycling plant in the Netherlands, with a capacity of 600 m3 per hour. We purify some of the industrial waste water from Dow Benelux and turn it into cooling-tower water. At the Harnaschpolder the Delft Blue Water research has been executed to use household waste water, after purification, as irrigation water for greenhouse complexes in Westland. This project was successful and options are being explored how to expand this concept.
