**5. Conclusion**

Scientists made an effort to reconsider the accessibility of clean and safe water due to the environmental impact of coloured dye wastewater disposal. It was documented that an occurrence of poisonous and coloured substances in dye-containing effluent has consequences on living organisms such as cancer, mutagenesis, allergies, and dermatitis. Textile effluent comprises a variety of detrimental xenobiotics which were found in higher concentrations and are hazardous to atmosphere as well as common people well-being. Since textile industries around the world releasing millions of gallons of contaminated sewage, toxicity dye-comprising effluent was an important problem. Contrarily, treating effluent that comprises dye is a substantial difficulty because no effective treatment that is also economically feasible currently exists. There are many tried-and-true and cutting-edge techniques for handling dye-containing wastewater. Wastewater containing dye can be effectively removed or degraded by employing physico-chemical process. Nevertheless, these techniques come with higher operational costs and unfavourable effects. In comparison to physico-chemical process, the bacteria-based technique to dye-comprising effluent treatment is more practical, ecologically safe, and socially and acceptable. Nevertheless, a drawback of biological techniques is that they are ineffective and necessitate a long period of administration. More study is needed to provide an advanced, waste-free technique and to lower ecological and human health threats when scaling up from lab use to the pilot level.
