ESR 4 – Project description

Converting Fe residual materials into filter-stable sorbent materials for P removal 

ESR 4: Oleksandr Bolielyi

Supervisor: Dr. Susan Reichel (G.E.O.S. Ingenieurgesellschaft mbH, Germany) / Co-supervisor: Prof. Stefan Peiffer (University of Bayreuth, Germany)

Project description:The project of ESR 4 comprises the development, testing and optimization of filter-stable iron based sorbent materials for P-removal. Conventional adsorbents are used in passive water treatment systems. To measure the effectiveness of the adsorbents in such systems the ESR will have to investigate key-parameters e. g. P sorption capacity and kinetics of the adsorbents, determine the influence of environmental variables to use the results for optimization of the adsorbent production conditions and develop design criteria for P-removal systems (e. g. cartridges) based on new filter-stable sorbent materials. Work will also focus on optimization of the sorbent properties inter alia in view of recycling or application as soil conditioner. The research will include a field test in North Bavaria and field and laboratory experiments. The project will be performed in close collaboration with the University Bayreuth and international partners and involves secondments in the consortium but also at companies which are partner organization in the P-TRAP project.

Secondments planned:

AQUAMIN: Applications of granular Fe-containing sorbents in environmental technologies (4 months)

UU: Investigating long-term changes in Fe(III) oxide based sorbents under field conditions (2 months)

US: Application of x-ray based techniques for Fe mineral characterisation (1month)
