A Critical Review on Advance Molecular Distortion Techniques for Textile Wastewater Treatment in Pakistan

Textile industry in Pakistan is a major economic contributor but also a significant source of environmental pollution. It discharges substantial portion of untreated wastewater containing hazardous organic and inorganic pollutants and synthetic dyes into natural water bodies. Conventional biological treatment methods used in Pakistan have proven inadequate in complete removal of these complex and toxic chemical effluents. Therefore, this study explored the application of molecular distortion techniques (MDTs) for effective treatment of textile wastewater at molecular level. In this study MDTs, refer to the utilization of some physical energy via extreme localized conditions like high temperature, applying electric filed, radiations and high pressure and sometimes produced free radical to break and alter molecular structure of pollutant for easy removal. Such techniques include processes like ultrasonic irradiation, photocatalysis, microwave-assisted oxidation, Fenton’s oxidation, photolysis, ozonation, and plasma treatment, etc. These methods have shown a great potential in degrading recalcitrant organic compounds, reducing toxicity, and improving the overall quality of treated water. Literature survey revealed that the MDTs are effective in breaking down pollutants at the molecular level, offering a more comprehensive solution than conventional methods. However, challenges such as requirements of specialized equipment, high operational costs, energy requirements, and the limit these large-scale applications. Despite these challenges, the integration of MDTs into Pakistan's wastewater treatment infrastructure could significantly reduce the impact of the textile industry on environment. Present study emphasized the need for further research to optimize these techniques for cost-effectiveness and scalability.
