Abstract Nowadays, treatment of chromium wastewater is very critical also important. The current study investigates the influence of electrocoagulation process parameters to reduce the chromium from wastewater. It has been observed that the initial pH (6), current density (25 mA/cm2), electrode distance (4 cm) and electrolysis time (30 min) were found to be optimum for a 97 % chromium removal. For the above said optimum condition, the electrical energy consumption was found to be 0.12 kWh/m3. A comparison between BBD and ANN shows high correlation coefficient values (R2 (ANN) > 0.90 and R2 (RSM) > 0.90). Results indicated that electrocoagulation process is a cheap and effective method to treat chromium wastewater.
