Contact Glow Discharge Electrolysis is a process of electrolysis with DC current to form electric sparks due to the electrons that undergo plasma excitation in the electrolyzed solution. Plasma electrolysis produce hydroxyl radicals, a powerful oxidant, with greater amount than other advanced oxidation method. This method is used to degrade much weight organic compounds such as dye. This research aims to evaluate the degradation of dye waste Remazol Brilliant Red (RBR) using Contact Glow Discharge Electrolysis method with air injection. The injection of air can increase hydroxyl radicals production and can decrease energy consumption. The condition used are dye concentration is 100 mg/L, NaCl 0,03 M, in addition of air bubbles and FeSO4 30mg/L applied power 450 W, and anode depth 2 cm. Dye degradation is measured by its absorbances with Spectrophotometer UV-Vis. The result of this research show that the efficiency of dye degradation in addition of microbubbles is increased with percentage of degradation was 99,63% in 30 minutes, final concentration of dye is 0,51 mg/L, COD 70.34 mg/L and specific energy is 3,129.395 kJ/mmol.
