LIFE Phos4EU 
The Phos4EU project focuses on scaling up the ViviMag process for extracting vivianite (hydrated iron(II) phosphate) from municipal wastewater treatment works. The ViviMag technology uses magnetic separation to extract vivianite from sewage liquors (see ESPP Technology Catalogue). The LIFE project will scale up from the existing pilot plant (automated 1 m3/h pilot) to representative scale (half full scale, 9 m³/h digested sludge inflow) and test at waste water treatment plants (Roermond Netherlands and Burgos Spain). The project aims to recover at least 60% of the phosphorus in the input sludge and produce significant quantities of vivianite (c. 600 tonnes). This will be used for trials and market chain evaluation of possible uses of vivianite including in fertilisers, in fire safety, as a pigment, and as an input material for phosphorus recovery process tests (separation of phosphorus and iron to produce useable products, such as phosphoric acid or P4, iron chloride). CO2 emissions reductions will be calculated. The project partners are Limburg Water Board, Brabantse Delta Water Board, Acciona, Aquaminerals and STOWA, in cooperation with Kemira (ViviMag patent owner), Wetsus, Delft University, ICL, Rijn en IJssel Waterboard and Haskoning.
