Abstract

The wastewater generated from Sago factories which cultivates Tapioca contains starch in both the suspended and dissolved forms. The starchy waste is very difficult to degrade by the conventional activated sludge process. In this paper the starch effluent (real and synthetic) was treated by an electrochemical method with the principal aim of eliminating COD using RuO2/Ti and PbO2/Ti anodes. Experiments were conducted to examine the effects of the operating parameters such as current density and concentration of NaCl on the COD removal efficiency. For the starch effluent containing high biodegradable organic content the current density of 7.5 A.dm-2 was required for both types of anodes to achieve a maximum removal of COD. The pseudo first order kinetics was found to be maintained throughout the reaction. Comparing the results of the electrooxidation of the starch effluent at the above two electrodes, the RuO2/Ti anode proved to be very effective than PbO2/Ti
