Description of the project offered:
Classified by the European Commission as a critical resource, phosphates (P) and their derivatives play a part not only as nutrients in agriculture (fertilisers), but also as inputs that are essential to the proper working of a variety of agri-food processes (preservatives, texturing agents, etc.) and industrial processes (metal processing, oil purification, etc.). As a consequence of worldwide population growth, the demand for phosphorous is of course growing with the world's known resources forecast to run out early in the 22nd century.
Recent meta-analysis of phosphorous flows at various geographic levels state that wastewater constitutes the main exit route for this element at the local level. In Europe, only 10 to 40% of phosphorous abatement takes place biologically, for lack of targeted strategies aimed at stabilising the enhanced biological phosphorus removal in activated sludge (EBPR). In practice, mainly eliminated by adding metal salts, phosphate recovery in a concentrated form is still an economical challenge.
In Europe, several dozen installations are equipped with a phosphorous recovery system, primarily from sludge and in struvite form. Currently, the main technological obstacles lie in dissolving the phosphorous – whether chemical or biological – present in the sludge, to increase its concentration prior to recovery (17 to 34% of the phosphates that are currently recoverable), and in the quality of the product we seek to obtain depending on its end use (fertiliser, component of industrial products). In practice we see that the financial side of phosphate recovery is viable in Wallonia if we improve EBPR and if we take into account lower OPEX relating to it (essentially through the reduced volume of sludge).

The ReCleanPhos project sets out to develop a range of technologies for recovering phosphorous present in urban wastewater. These phosphorous recovery units will be designed so that they can fit into the functional layout of current wastewater treatment plants whether during revamping or new building projects.
In particular, this project proposes to increase phosphorous recovery yields by encouraging the "selective dissolution" of the phosphates upstream (and not downstream) of any anaerobic sludge treatment performed. To do this, the ReCleanPhos process will include a unit for managing phosphate purifying and pre-concentratrating environments coupled to various phosphorous recovery installations. Concentrated and then extracted from the sludge by aqueous means, special attention will be paid to purety (metals, xenobiotics, etc.) and to the product properties obtained to make economical reused easier by the fertiliser or phosphate industries (e.g. struvite, calcium phosphate).
