Landfill leachate (LL) is the liquid waste generated from solid waste dumping site. Due to the high toxicity and high COD-BOD ratio of leachate, it is not possible to treat it in conventional wastewater treatment plant. There is a special treatment required to treat it. In this study, a complete batch electro-coagulation (EC) process is used to treat the LL. Aluminum (Al) and iron (Fe) electrodes were used for effective removal of COD by varying the treatment parameters such as initial voltage (V), current (A), initial pH, treatment time (t), electrode spacing (s), and number of electrodes (n). The maximum COD removal by Al electrode is found to be 85% at 25 V and by Fe electrode is 45% at 20 V. The optimum number of electrodes is found to be 6 at alkaline pH range.
