Dairy waste from industrial activities may affect environment and human health. Many methods have been used to treat dairy waste such as biological treatment, coagulation and sedimentation system, DAF system (dissolved air flotation) and many more. The strength of organic contaminants from dairy waste are very high compared with other typical waste streams such as domestic and municipal wastes. Dairy wastes affect the chemical composition in the water and contribute negative impact to animal and aquatic plant. The objective of this research is to determine the ability of electricity to treat dairy waste. This study was focus on the effect of current density, concentration of sample and duration of current flow. Simple electrochemical cell with steel plate (anode) and aluminum plate (cathode) was used for this study. The effectiveness of this method was determined by measuring BOD and turbidity removal. Based on this study, it was found that electricity was able to treat dairy waste. The amount of current density, duration of electric current flow and concentration of the sample does affecting the percentage of turbidity and BOD removal. Electricity was able to remove turbidity more then 99.0 %. While for BOD, the removal rate was below than 80.0 %.
