摘要：The removal of COD and turbidity from dairy wastewater was experimentally investigated using directcurrent electrocoagulation (EC). In the EC of dairy wastewater, the effects of initial pH, electrolysis time, voltage anddifferent electrodes were examined. The batch experimental results revealed that the removal efficiencies of the overallNitrates, COD depend on the nature of the electrode material. The optimum operating range for each operating variablewas experimentally determined. With this latest approach, optimal values of voltage, initial pH and electrolysis timewere 20V, 6.9 and 30 min respectively. The batch experimental results revealed that COD and Nitrates in aqueousphase were effectively removed. The overall COD and Nitrates removal efficiencies reached 50% and 86.8%,respectively. It was observed that the removal efficiency is directly proportional to the electrode material, contact timeand voltage and inversely proportional to electrode gaps.
