Dewaterability of sludge produced by Wastewater Treatment Plants (WWTPs) is often poor, reaching less than 25% dry solids (DS). Electro-dewatering could be a suitable technique to further reduce water content of the sludge by up to 20%. We investigated the parameters affecting pressure-driven electro-dewatering of anaerobically and aerobically stabilised, mechanically dewatered, sludge samples. The applied electrical fields have been set at 10, 15 and 20 V/cm in order to evaluate total energy consumption and final DS

Abstract

Dewaterability of sludge produced by Wastewater Treatment Plants (WWTPs) is often poor, reaching less than 25% dry solids (DS). Electro-dewatering could be a suitable technique to further reduce water content of the sludge by up to 20%. We investigated the parameters affecting pressure-driven electro-dewatering of anaerobically and aerobically stabilised, mechanically dewatered, sludge samples. The applied electrical fields have been set at 10, 15 and 20 V/cm in order to evaluate total energy consumption and final DS
