Energy-efficient evaporation of excess water in a test at the SAC's Legler Hut at 2280 m'a.s.l. (Michel Riechmann, Eawag) - What has been a purification process in wastewater treatment plants for decades can also be used decentrally or semi-centrally as a recycling process for nutrients. Early separation of "solid and liquid" plays a key role here. It allows for flexible solutions in terms of process technology, especially in the treatment of urine. New studies also show that the processes can be used not only for human urine, but also for that of cows or pigs. Worldwide, the demand for fertiliser for agriculture is increasing. This makes the recovery of nutrients from wastewater interesting.
