An overview on the viable methods for textile wastewater treatment

Abstract

The textile industry is one of the major polluters of the environment, primarily due to the types and quantities of wastewater it produces. It is estimated that 20% of global water pollution is caused by textile processing, meaning that these processes generate enormous amounts of wastewater. Generally, this wastewater contains high levels of suspended solids, dyes, salts, pesticides, non-biodegradable organic substances, and heavy metals. The decline in water quality, along with increasingly stringent environmental protection regulations, has led the textile industry to turn to sustainable wastewater treatment methods that help reduce the global water footprint. This paper reviews some viable methods used for the treatment of wastewater originating from the textile industry. The focus is on advanced treatment techniques, such as adsorption, membrane-based filtration, electrochemical processes, and advanced oxidation. These methods offer potential solutions to mitigate the environmental impact of textile wastewater and promote sustainable water management practices.
