Integral Management Model for Phosphorus recovery and reuse from Urban Wastewater

PHORWater project, framed within the LIFE+ funding with the contribution of the European Union, aims to increase awareness of the environmental problem of phosphorus and its recovery from wastewater treatment plants.

In PHORWater, the phosphorus from the influent of the wastewater treatment plant (WWTP) is biologically removed from the water line and concentrated at the waste activated sludge (WAS) produced so lately in order to be removed from the sludge for its recovery as crystallized struvite. In this way it is expected to:

  • Optimize the process of biological phosphorus removal at the water line of the WWTP.

  • Retrieve the phosphorus removed as struvite through the development of a crystallization reactor.

  • Increase the availability of phosphorus for agricultural use.

The main objective of PHORWater is to increase awareness of the environmental problem of phosphorus and to give an innovative solution for the recovery of phosphorus at the WWTP facilities that decreases its environmental problem, so the project is focused on the development of a good practice manual to maximize phosphorus recovery at the WWTPs as well as on validating that enhanced biological phosphorus removal (EBPR) combined with an integral management of P in the WWTP, and with struvite recovery by crystallization in a stirred tank reactor is an economically viable technology.

The overall treatment will provide the best phosphorus management for a specific WWTP. The protocol could help to decide the better option for other WWTPs of similar characteristics with little modifications and sample analysis.

PHORWater project aims to give an answer to the environmental problem of phosphorus by reducing the amount of phosphorus discharge and the associated problems of eutrophication and obtaining an alternative source of phosphorus that could reduce its mineral extraction.

The project will take place at the WWTP facility of El Cidacos (Calahorra, La Rioja, Spain), where it will be implemented the best configuration for biological phosphorus removal with a crystallization reactor at the side streams of the sludge line in order to recover phosphorus as struvite and analyze the feasibility of the obtained product as agricultural fertilizer.

The Project will be developed by DAM (Depuración de Aguas del Mediterráneo) with the collaboration of CALAGUA Research Group (Universidad Politécnica de Valencia) and LAGEP Research Group (France).
