According to the state of the art treated wastewater is not currently recycled, but passed into the receiving water. This waste of water resources is a problem especially in arid areas. But also in megacities, a decentralized cleaning and recycling of the wastewater should be strived for, because this can reduce infrastructure and transport costs.
Approach of Research
We solve that problem by coupling anaerobic waste water treatment with a bioenergy facade. By doing so, biogas is produced and the nutrients in the waste water are released.By coupling with a bioenergy facade the nutrients and the treated water become reused and the water is further treated by elimination of micropollutants.
Aim of research
Decentralized anaerobic waste water treatment is state of the art. Based on this SSC developed technology for a successful coupling to a bioenergy facade. The focus of an International consortium under der lead of SSC is now to establish the frame conditions which allow to run respective devices in North African countries.
