Abstract:Leachate is highly complex and polluted waste water that is produced by the introduction of percolation water through the body of landfill treatment. Leachate treatment is essential as it could threaten the surrounding ecosystem when discharge as it is and when it mixes with groundwater. Various leachate treatment technologies like coagulation- flocculation, adsorption by activated carbon, biological treatment and reverse osmosis are reviewed and there treatment efficiency depending on operating condition of India is discussed. This paper presents, treatment of solid waste leachate using Electrocoagulation (EC) process. The sample of leachate was collected from Belgavi Municipal solid waste site. The effects of process variables such as pH, applied cell voltage, and operating time were investigated on pH, acidity, alkalinity, total solids, turbidity, BOD and COD removal. The Electrocoagulation process was carried out in a batch reactor of 1.5 liter capacity and samples of 1000 ml were taken out for batch at 30, 45 and 60 minutes of operation. Results obtained from the experiments showed that BOD (93.1%) ,Total suspended solids(91.17%) ,COD(84.42%) removal was strongly influenced by the initial pH. The highest BOD and COD Removal efficiency of 93.1% and 84.42% were obtained.
