demonstrate innovative solutions

LIFE PHOS4EU project aims to develop and demonstrate a solution for recovering up to 65% of the phosphorus’ content in wastewater for its later reuse, in order to reduce the dependence that the European Union has on the import of this mineral.

This project proposes the implementation of the innovative technology ViviMag, based on the iron phosphate precipitation from wastewater to mineral vivianite from the sludge of the anaerobic digesters. Vivianite is recovered by magnetic separation taking advantage of its paramagnetic qualities. It is expected to recover almost 80% of the potentially generated vivianite, which represents between 60% and 65% of the phosphorus content in the influent of a WWTP.

ACCIONA will implement this technology in a pilot plant located at a WWTP in Castilla y León (Spain). This pilot plant will demonstrate the viability of vivianite production and its use as a fertilizer in the agricultural sector.

LIFE PHOS4EU Project, co-funded by the European Commission’s LIFE programme, will be coordinated by the Brabant Delta Water Authority, Netherlands, and count on the participation of companies dedicated to water treatment, such as Aquaminerals and, of course, ACCIONA through its Water business. On the other hand, the Foundation for Applied Water Research (STOWA) and Waterschapsbedrijf Lindburg (WBL), both Dutch leaders in the Innovation Sector, also participate in.
