Electro-dewatering
(EDW) is an energy-efficient method for sludge
dewatering. In this study, effects of piecewise electric field operation
on EDW were investigated by experiments and simulation. Operational
parameters were studied mainly in terms of sludge resistance variation
during electro-dewatering process, which were evaluated by linear
sweep voltammetry (LSV) analysis. Simulation of the sludge cake electro-dewatering
processes was developed and validated, based upon time-dependent experimental
data of electric currents and filtrate weights. The modeling results
were in good agreement with experiments. It was proved by experimental
and modeling results that the piecewise operation has positive effects
on key performances of EDW devices, that is, limited water content,
space-time yield, and mass specific energy consumption.
