Abstract: The textile industry, one of the essential and largest sectors, requires fresh water and generates a substantial quantity of effluents containing mineral salts and dyes, both concentrated. To address this problem, the present study deals with the removal of COD and BOD from textile wastewater by activated charcoal. The various adsorbent dosage, contact duration and temperature effects have been studied in this investigation in order to remove COD and BOD. Adsorption isothermal data could be interpreted by the Langmuir and Freundlich equations. The maximum COD and BOD reduction was found to be 97.6% and 93.7% respectively.

Keywords: COD, BOD, activated charcoal, dyeing mill wastewater, adsorption
