The aim of this research was to optimize the operating parameters in electrocoagulation process such as voltage, electrode distance and time for the removal of chemical oxygen demand (COD), biological oxygen demand (BOD) and total suspended solids (TSS) from dairy wastewater. The results showed that the optimized conditions were voltage of 25V, electrode distance of 3 cm and time of 45 min. Under the conditions, the removal efficiency of COD, BOD and TSS were 86%, 84% and 82% respectively.
