Description The performance of the batch electrocoagulation process for the treatment of real crude vegetable
oil refinery wastewater with high COD using sacrificial aluminum anode was explored in this research.
Effects of operating factors such as electrolysis time (0–60 min), applied voltage (10–20 V) and electrode spacing (2–4 cm) on the COD removal were investigated. Mathematical model relating these
key operating factors and the COD removal was developed using Box-Behnken design. 3-D response
surface plots showed that the COD removal significantly increased with increase in electrolysis time
and applied voltage till the optimum value. COD removal decreased, when very short or excessive
electrode spacing was fixed. Experimental COD removal of 70.8% was attained at the optimized conditions and observed to be in reasonable agreement with the prediction by the Box-Behnken design.
