Abstract

The decolorization and Chemical Oxygen Demand (COD) removal of Biogas Production Wastewater (BPW) were investigated by using electrocoagulation (EC) in a batch experiment. Iron and aluminium electrodes were compared. Variations of current density (20, 35, 50 A/m2), initial pH (4.5, natural, 8.5) and electrolysis time (30, 50, 100 minutes) were conducted for decolorization and COD removal efficiency of BPW. The result showed that decolorization efficiency and COD removal are 31% and 28% for aluminium electrode at natural pH with 100 minutes of electrolysis time and current density of 35 A/m2. However, using iron electrode could not remove color and only 15.70% of COD could be removed at natural pH, 100 minutes of electrolysis time and current density of 50 A/m2.
