phosphate
recovery from sewage sludge via magnetic separation of vivianite

Anticipated start: July/August/September/October 2023
Duration: 6 – 12 months
Location: Wetsus Research Institute, Leeuwarden, the Netherlands

There are a few possibilities for allowances:
– The allowance for students is €200. The student can apply for ‘Wetsus Grant’ allowance (€200 extra; an internal committee decides if the allowance will be granted).
– Students can apply for Erasmus; (if the Erasmus grant is less than €400, the student can apply for the Wetsus Grant).
– Erasmus
*The Wetsus Grant allowance is not guaranteed and must be approved by the Grant Committee.

Project background

For wastewater treatment plants dosing Fe to remove P, up to 90% of P can be present as vivianite (Fe3(PO4)2*8H2O). This mineral is both thermodynamically and kinetically favored in reducing environments such as in the anaerobic digester or in excess sludge left in anaerobic condition for a few days. Since vivianite is paramagnetic, its recovery from sludge is possible via magnetic technologies. The internship focuses on studying vivianite formation in sludge and its recovery efficiencies with the magnetic separation. You are also welcomed to contribute to the topic of the project and shape it according to your interest!
