Last March 22nd, 2016, during the 11th IWA Specialist Group Conference on Wastewater Pond Technologies, Sofía Grau, from Depuración de Aguas del Mediterráneo, made a review of the results of PHORWater LIFE+ project at the parallel session on Innovations in Wastewater Treatment.
Over the last years Wastewater Industry has made a major contribution to the European aims of a Circular Economy, in which materials from wastes are returned to productive parts of the economy, letting to identify the potential recovery resources available. Energy recovery studies had reveal that energy neutral wastewater treatment will be a real possibility within the next two decades therefore attention is now focused on the development of economically viable Nitrogen and Phosphorus recovery technologies.
The parallel session went over those technologies that have recently emerged and been successfully applied for resource recovery and the benefits they bring not only to the environment as to the raw materials supply. It also looked to the future and examined other potential resources that might be recovered economically and considered the best approaches to ensure the commercial success of any research initiatives investigating such routes.
PHORWater project, within the LIFE+ founding from de European Commision, brings an integral management protocol to enhance phosphorus removal at WWTP and its recovery as struvite, an slow release fertilizer, reducing phosphorus discharges to waterways and phosphorus external demand. The solution has been implemented at Calahorra WWTP and the obtained struvite is now performing agricultural application assays. Sofía Grau presented the results obtained so far by the implementation of the phosphorus recovery protocol combined with the struvite crystallization reactor.
PHORWater consortium is made up of DAM as project coordinator, CALAGUA, research group from University of Valencia and LAGEP, Automation and Process Engineering Laboratory from Lyon 1 University.
