Abstract
The treatment of crude oil contaminated water using Electrocoagulation (EC) and Coconut Shell Ash (CSA) derived supporting electrolyte was investigated. Aluminium electrodes produced from recycled beverage cans were used in the setup. Nine experiments were designed using the Taguchi’s L9 orthogonal array. The operating voltage (10 – 30V), electrolyte concentration (5 – 15 g/l), and treatment time (10 – 30 mins) were chosen as controllable factors, and their impact on Chemical Oxygen Demand (COD), turbidity, Oil & Grease and electrode consumption were studied. The Maximum COD, turbidity, oil and grease removal of 65.47% , 100%, and 93.26% were obtained at 20, 30 and 10V, respectively. Increased electrode consumption was evident in the experiments without the CSA derived electrolyte. This research successfully demonstrated the viability of EC for remediating crude oil-contaminated water.
