Reactive textile dyes (RTD) are widely used in textile industry and they are commonly found in aquatic systems. Vacuum Ultraviolet (VUV) process is among the promising effective and green water/wastewater treatment processes and was applied for the decomposition of aqueous RTD namely, Synozol Red KH-L and Synozol Yellow KH-L with the aim of minimizing sludge production during the treatment. The effects of flow rate, initial pH, initial RTD concentration, sleeve materials and NaCl were reported. Our VUV focused treatment results show that flow rate had marginal impact, pH played an important role, slowest at pH= 11, for the discoloration rate of RTD. Presence of NaCl decreased the decomposition of RTD. Synthetic high purity quartz sleeve significantly enhanced the elimination of RTD, increasing discoloration rate constant as almost 6 times higher. Kinetic analyses showed that VUV induced discoloration of RTD followed a pseudo first order reaction kinetic. The results of this study indicate that the VUV based Advanced Oxidation Process (AOP) can successfully and environmentally decompose RTD in water with no sludge production and without requiring addition of chemicals to produce hydroxyl radical (center dot OH).
