Abstract

The manufacture of the Sasirangan home textile industry involves coloring and dyeing processes using synthetic dyes in large quantities. These contaminants of dyes and organic materials would cause high color and chemical oxygen demand (COD) contaminants values. This study aims to characterize the wastewater of batik-modified Sasirangan and determine the effect of current density and length of operating time on color removal and reduction of COD in Sasirangan home textile industry wastewater through the batch electrocoagulation process. The method used in this research is an electric current flowing in the same direction to the Sasirangan home textile industry wastewater in a reactor with dimensions of 310  180  240 mm3. The electrode used is aluminum alloy type 1100. The aluminum/aluminum (Al/Al) electrode is used in this electrocoagulation (EC) process, then connected to a direct current (DC) power supply. The experiment was carried out at room temperature using an electrode distance of 2 cm with variations in the time of the electrocoagulation process for 15–120 minutes. The experiment was repeated for variations in pH (4–9) with a current density of 3.5–5.5 mA/cm2. Furthermore, an analysis of the color removal and the decrease in the concentration of COD was carried out. The results showed that the contaminant content in Sasirangan home textile industry wastewater decreased significantly, whereas the optimal conditions for the EC reaction were determined using color and COD removal efficiency parameters. The decrease in color and COD concentrations occurred at a current density of 5.5 mA/cm2 with a pH of 4 for 120 minutes, around 1110 PtCo and 90.4 mg/L of COD, respectively

Abstract

Electrocoagulation process on batik-modified sasirangan textiles wastewater treatment used aluminum electrodes (Al6061-T6) from the waste scraps of the aluminum furniture industry. Batch experiments at room temperature were carried out at an initial of pH 4. The parameters effect such as time reaction (5– 120 min), current density (3.5–5.5 mA/cm2), and the distance between the electrodes (2–5 cm) were evaluated to determine the optimum condition for COD and BOD5 removal. The optimum condition for the electrocoagulation process on batik-modified sasirangan textiles wastewater was selected at a time of 15 minutes, 5.5 mA/cm2 of current density, and 2 cm of electrode distances. Under those conditions around 59.60% of COD and 62.47% of BOD5 removal efficiencies were achieved. Both kinetics in COD and BOD5 removal with electrocoagulation reaction follows the half-order reaction. Reusing the leftover aluminum from furniture manufacturing as electrodes in the electrocoagulation process is quite effective for treated batik-modified sasirangan to meet the quality standard of clean water
