Treating water for human consumption is costly and energy intensive. Is there a more efficient way to do it?
Gunter Pauli thinks so.
In the first innovation explored by PhD, entrepreneur and eco-designer Pauli in the ZERI Foundation’s two-year essay and video project The Blue Economy, 100 Innovations, 100 Million Jobs, the self cleansing mechanism found in natural water sources is identified as a possible solution to treating water without the huge cost in chemicals and energy.
Rivers clean their own water all the time, and for free, Pauli says in his essay. Their secret? A combination of gravity and a swirling motion called the vortex. If there were a way to replicate that function in water treatment facilities, it would mean energy savings and less cost for producers down to consumers.
This is the idea that inspired Swedish inventors Curt Hallberg and Morten Oveson to design and build the technology to replicate the self-cleansing function of the vortex.
Based on this technology, they started a company, Watreco AB, initially serving water-dependent businesses like ice rinks and golf courses.
