Physical-chemical method such as electrocoagulation (EC) and coagulation-flocculation processes work well for the treatment of stabilized leachate. This study investigated the efficiency of combined treatment (electrocoagulation and conventional coagulation) in removing colour and ammonia nitrogen (NH3-N) from stabilized leachate. For this combined treatment, the Fe and Al electrodes with the addition of composite coagulant (PAC and TF) were used. The considered factors were pH, current density, and duration of current flow. It was observed that, the highest removal of colour and NH3N were 96% and 13% at applied current density of 100 A/m2 that equal to 0.5 A and 20 minutes respectively. For single EC treatment, the highest removal was 88% for colour and 25% for NH3N at 60 minutes by 150 A/m2 that equal to 1.3A. Thus, it showed that the combined treatment performed better than single treatment in removing colour while reducing the current, and shorten the duration of current flow.
