Treatment of Oily Wastewater by Electrocoagulation Process and Optimization of the Experimental Conditions Using Taguchi Method

Abstract

In this study, electrocoagulation process was used for chemical oxygen demand (COD), total organic carbon (TOC) and turbidity removal from oily wastewaters and Taguchi experimental method was used to determine optimum operational conditions. For this purpose, 5 significant factors (initial pH, current, electrolysis time, air injection flow and electrode surface area) effective in COD, TOC and turbidity removal from the wastewaters were optimized. These experimental factors were handled in 4 levels and experimental conditions were optimized through performing L₁₆ (5⁴) tests with orthogonal series of Taguchi method. Optimum conditions were identified as: initial pH of 6 (pH_i level 3), current of 1A (I level 2), electrolysis time of 20 min (EC_time level 4), air injection flow of 2 L/min (air flow level 3) and electrode surface area of 210 cm²(electrode surface area level 2). Under these conditions, experimental and estimated pollutant removal efficiencies were respectively identified as 92.1-95.6% for COD, as 78.5-80.2% for TOC and as 96.2-95.7% for turbidity. Closer experimental and estimated values indicated the available use of Taguchi method for electrocoagulation process.
