Decolorization of Textile Wastewater Using the Electrocoagulation Process

In the environmental pollution talk, wastewater treatment is one of the major issues currently. The current situation of population growth and industrial evaluation contributes more to wastewater generation. In particular, the modern world depends more on the textile industry, which generates a significant amount of industrial wastewater. Textile industry effluent is a major concern among all dye-producing industries as it releases complex compounds in wastewater, which also occurs in large volumes. Furthermore, these effluents need an advanced treatment process to be discharged into the receiving bodies as per discharge standards. This experimental study discusses the degradation of Reactive Yellow 145 by using the Electrocoagulation Process. This dye is widely used in the textile industry and is highly toxic when released into the environment. The principle objective of this study is to investigate the decolorization efficiency based on various parameters like applied voltage, pH, reaction time, and salt concentration (NaCl). Iron electrodes were used in this electrocoagulation study. Decolorization efficiency of up to 96% has been achieved at optimum conditions of pH 6, 30 min of reaction time, 18 V of applied voltage, and 0.4 g/l of salt as electrolyte.
