Abstract
Textile wastewater with high concentration of dye caused by coloring and finishing process has been polluting the environment. Plasma is one of wastewater treatment required to degrade the dyes. In this study, plasma corona discharge was used to degrade the batik wastewater. Plasma corona discharge is generated by an AC voltage of 11.5 kV through one or two pair stainless steel electrode with diameter of 2±0.05 mm. The electrodes are placed 3 mm above the batik wastewater. The result show a decrease absorbance at wavelength of 400-500 nm. The treatment time of one pair electrode is 2 hours and 3.5 hours. While for two pairs electrode treated in 1 hour and 1.5 hour to get approximatelly same result with one pair. The percentage degradation of dye for one and two pairs of electrodes are 39.08; 50.85; 39.08; and 42.83%, respectively.
