Abstract

This study aimed to use electrocoagulation to produce biogas and to treat slaughterhouse wastewater at the same time. Wastewater was fed into a constructed single cell chamber. The parameters were input voltage, amount of electrolyte, and amount of wastewater. The variables were system voltage, system current, BOD, pH, DO, TSS, COD, and gas produced. The experiment run for an hour. The system voltage was measured using digital multimeter. The DO and pH were measured using DO/pH meter Kit. The COD was measured using spectrophotometer. Gas production was measured using displacement method. Duncan's Multiple Range Test (DMRT) analysed the results that showed that varying amount of wastewater affects the gas production only. System voltage and system current are significant with voltage and electrolyte while gas production is significant with amount of electrolyte, amount of wastewater and voltage input. Optimum values were obtained and verified using Response Surface Regression and Analysis of Variance. Verified and predicted values were compared using DMRT. Factors that may effect the deviation of verified values from predicted are: improperly calibrated equipment, composition of the wastewater, and corrosion rate of electrodes.
