Design Framework for Electrokinetically Enhanced Dewatering of Sludge

Effective dewatering of sewage sludge (an internationally challenging waste), to remove liquid wastewater for treatment and render the residual solid waste usable, is economically and environmentally desirable. This EPSRC-funded research demonstrated in the laboratory that electrokinetics is an effective and viable technique to increase the rate and degree of dewatering achievable, and establishes a theoretical and practical framework for optimising cost and technical efficiency. Solar-powered electrokinetic dewatering using inert (non-corroding) electrodes now presents an international transformative technology opportunity. The research has been taken forward to pilot-scale field trials by a water company.
