Abstract

Massive environmental issues have been brought on by the improper handling of different wastes, particularly dye effluents from textile industry, which has ultimately affected human health. Even with ongoing efforts, terminal treatment remains the most common method for minimizing the pollution caused by dye effluents. This study summarized research on textile dye effluent treatment from 2000 to 2024 and briefly reviewed key techniques such as AOPs, Coagulation, flocculation, membrane, adsorption, electrocoagulation, photochemical treatment and Fenton process. Since biological treatment has great performance, including high efficiency and environmental friendliness, it has garnered increasing attention from researchers in the past few years. Comprehensive investigations on the optimisation of techniques and cost-effectiveness were necessary, though given by severe physiochemical circumstances of dye effluent. Integrated or combined treatment approaches are therefore advised, with improved performance and multi-function. This article presented some of the problems strategies such as Genetically engineered micro- organisms, biosorbents and bioremediation by nanoparticles residuals in the treatment and the high salinity in the effluent and offered suggestions for possible fixes. This review also advanced the idea that the future path of TDE treatment should be focused on achieving multi-function, recycling, and intensification. The objective of this review is to give scholars a diversified overview of the approaches used in this field and a means of improving TDE pollution problems.
