abstract
Textile wastewater (TW) is one of the most hazardous wastewaters for the environment when discharged
without any proper treatment. A comparative study was conducted to investigate the removal efficiency
of color, chemical oxygen demand (COD) and turbidity from real textile industry wastewater using
anaerobic IC reactor and Fenton’s process with and without pH adjustment. Color, COD and turbidity
removal efficiencies have been studied for 25%, 50%, 75% and 100% textile wastewater. Results
demonstrated that a maximum color removal efficiency (>92%) was recorded in Fenton’s process at
pH 3 for 100% sample. However, maximum COD removal efficiency of 87% was observed in IC reactor
for 100% sample. Thus, Fenton’s reagent at pH 3 was found highly effective for color removal and IC
reactor observed to be efficient for COD removal. Furthermore, Fenton’s process without pH adjustment
was found higher turbidity removal efficiency as compared to other treatments. Findings from this
suggested that the selective treatment process could be highly promising for the decolorization of textile
wastewater and can also be practically implementable.
