Electrochemical Disintegration of Activated Sludge Using Ti/RuO₂ Anode

Abstract:

Electrochemical process is one of the most effective methods to enhance sludge disintegration. In this study, Ti/RuO₂ anodes were prepared by Pechini’s method and the electrode surface morphology was characterized by FESEM and EDAX. The effects of various operating conditions were investigated including initial pH value of sludge, sludge concentration, electrolysis time and current density. The study showed that the removal efficiencies of TS, VS, TSS and VSS increased with the increase of pH in the alkaline range, electrolysis time and current density but decreased with the increase of initial sludge concentration. The application of electrochemical process using Ti/RuO₂ electrodes enhanced the sludge disintegration for possible subsequent biological treatment.
