University of Valencia developed a methodology for exploitation of wastewater in water-scarce areas

The University of Valencia has developed a multidisciplinary working methodology capable of detecting significant water deficit areas and studying the possibilities of reusing reclaimed water. This project is based on a contract-agreement signed between the academic institution and the Regional Ministry for Agriculture, Environment, Climate Change and Rural Development, with the objective of developing applied research projects related to water treatment, aquatic and marine ecosystems, water resources management and aquifer recharging.

The methodology has been applied as a particular case in the Pinedo Water Treatment Plant (Valencia, Spain) and is proposed for reusing Pinedo’s plant reclaimed water to obtain nutrient-rich (nitrogen with ammonia and orthophosphate) flows, which at the same time have a low content of solids and are free from pathogens and contaminants in accordance with the legislation. With respect to the reduction of energy consumption, several modifications are proposed to improve the operation of the sewage station, so that membranes of ultrafiltration should be incorporated after the primary decantation, and organic matter of the flow should be used entering the plant to obtain energy. Similarly, a reduction of the retention time of the activated sludge reactors is also suggested, thus minimising the energy consumption associated with the ventilation of the reactors.
 
The University of Valencia has carried out the project with the multidisciplinary participation of its research groups:
Group of Soils, Waste and Environment
Water Quality and Restoration of Aquatic Ecosystems Group
Mintota Research Group
Water Economy Group
Climatology from Satellites Group
Food and Environmental Security Group
Water Quality Group
Intelligent Data Analysis Laboratory
 
The principal investigators of this multidisciplinary activity are: Rafael Boluda Hernández, Antonio Camacho González, Pilar Campins Falcó, Francesc Hernández Sancho, Ernesto López Baeza, Yolanda Pico García, Aurora Seco Torrecillas and Emilio Soria Olivas. 
 
Two EIP Water Action Groups have collaborated in the Project, namely AnMBR (Anaerobic Membrane Bioreactor for Recovery of Energy and Resources to achieve Sustainable Water Reuse) lead by Aurora Seco Torrecillas and RESEWAM-O (Remote Sensing for Water Management Optimization  lead by Ernesto Lopez-Baeza.
