Performance evaluation of a bipolar electrolysis/electrocoagulation (EL/EC) reactor to enhance the sludge dewaterability

► This study explores the efficiency of the EL/EC reactor for sludge dewaterability. ► Maximum reductions in CST and SRF were observed at 20 min and 30 V. ► A maximum sludge disintegration of 2.5% was achieved by the reactor. ► Electrocoagulation helped to achieve a higher degree of sludge disintegration. ► Electrocoagulation also maintained a desired degree of sludge dewaterability.
