Location: Wetsus, European Centre of Excellence for Sustainable Water Technology, 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 description

Saline wastewater streams can be found in different industries, i.e., fish processing, chemical, petroleum and leather. The organic pollutants from these streams could be treated using up-flow anaerobic sludge blanket (UASB) reactor. This anaerobic process could convert the organics into CH4 energy- and cost-effectively compared to the physical/chemical treatment. UASB reactor could operate at a high organic loading rate mainly due to the anaerobic granular sludge present in the system where a high biomass concentration can be achieved. Granular sludge is a spherical biofilm encapsulated with extracellular polymeric substance (EPS) excreted by microbes. EPS from other sources, such as aerobic wastewater treatment process, showed the potential to be used as a nature flocculant, coating material etc. The potential of the EPS from anaerobic granular sludge is yet to study. In this project, we aim to start up UASB reactors and explore the resource recovery potential using anaerobic granular sludge.
