Advancements, principles, and trends in progressive catalytic approaches for sustainable industrial wastewater treatment

Abstract As pollution rises and spoil the living environment, prevention must be prioritized, requiring creative safety measures. Since a future threat might be the availability of drinkable water, it is imperative to adequately treat industrial wastewater, which is a substantial source of pollution, before its discharge. Conventional approaches frequently prove ineffective in dealing with multiple impurities, presenting a significant barrier to the purification. Catalysis offers innovative, efficient, and eco-friendly solutions for industrial wastewater treatment. This study investigates innovative catalytic methods for the efficient and successful treatment of industrial wastewater. A particular attention is given to processes using real wastewater from industrial plants. Researchers prioritize the development of improved catalysts and electrocatalysts to decompose pollutants into less hazardous or beneficial substances without causing any negative influence on the environment. Catalytic procedures have remarkable efficiency in breaking down contaminants, emphasizing their vital role in sustainable wastewater treatment. To progress in this area, it is crucial to concentrate on enhancing catalytic processes and investigating novel materials. The future of industrial wastewater treatment plants is in the integration of optimized Advanced oxidation process catalysts with optimal membrane technology owing to its efficiency in separately handling the degradation of industrial wastewater.
