Circular Economy innovation by Dutch water supply company Vitens helps Royal HaskoningDHV obtain value from water globally
AMERSFOORT, THE NETHERLANDS, 12 January 2014 –/WORLD-WIRE/– International engineering and project management consultancy Royal HaskoningDHV has joined forces with Dutch water supply company Vitens to help other drinking water companies around the world recover humic acid, an organic fertiliser.
Humic acid is often discharged currently as a waste product during the drinking water blanching process. Thanks to this innovation from Vitens it can now be reclaimed sustainably in its pure form, providing an organic soil improver.
Royal HaskoningDHV will be marketing this unique Dutch technology, which won the international Aquatech Innovation Award 2013, on a global scale. Ms Lieve Declercq, chair of the Vitens Executive Board and Ms Esther Bosman, Royal HaskoningDHV’s Director Water Technology in the Netherlands, signed a partnership agreement to this effect on 8 January 2015.
Ms Esther Bosman said: “Royal HaskoningDHV and Vitens are two very different players in the water market. We both have our own interests and yet we are able to join forces. We now have a unique Dutch innovation at our disposal which will present a solution to global challenges. Together, we will be able to make a difference and contribute to the circular economy.”
From waste product to soil improver
The drinking water production company Spannenburg, in the Dutch province of Friesland, provided the platform for Vitens to apply its innovative combination of unique technologies – ion exchange and various existing membrane technologies – to blanch drinking water. This process creates a residual stream of water and salt as well as humic acid, a highly valuable organic substance from peaty soil which gives water a yellowish hue. Water and salt are completely reused during the production process while the humic acid, once regarded as a waste product, can now be utilised as a soil improver in the agricultural sector.
