Abstract: Large quantity of carwash wastewater is produced per day from carwash stations. It widely contains a significant quantity of oil and grease, suspended solids, heavy metals and organics, along with chemicals from detergents. Electrocoagulation with new configuration was investigated to remove COD, turbidity, Total Dissolved Solids (TDS) from wastewater and reduce its Electrical Conductivity (EC), so, it can be valid for reuse. Aluminum foil thin layer is used as an electrode in this treatment process. The effects of air flow at different voltage and treatment time were studied. The best result was found at 30 V and 5 L/min at treatment time 90 min where the removal efficiencies of COD, turbidity and TDS were 96.99, 99.87 and 20.59%, respectively and reduced electrical conductivity to 683.594 μS/cm.
