Treatment of textile waste water using activated carbon method

Abstract

The textile industry extensively uses chemicals to dye fabrics, resulting in significant water pollution. The chemicals mix with water and harm the aquatic ecosystem. As a consequence, untreated wastewater from textile industries is discharged, posing a threat to water quality and human health. Several methods exist for treating such wastewater, including chemical and biological processes, and significant developments have been made in managing these wastewaters sustainably and recovering resources from them. Currently, there is a growing shift towards sustainable management of such wastewater, with a focus on resource recovery. This paper explores the most cost-effective methods for treating dye industry wastewater, specifically through filtration techniques. An experimental prototype was developed that utilized a three-layer filtration system composed of natural elements like coconut shell and coir, fine and coarse aggregates, and activated carbon to treat dyed wastewater. The results were compared with pre-treatment and post-treatment samples.
