STUDY OF ENZYMES FOR WASTEWATER PURIFICATION: A Review

Due to contact of variety of chemicals, pharmaceutically active compounds and many other effluent with water causes wastewater. Many hazardous contaminants (dye and phenol contaminants) badly effect on human and ecosystem, due to their toxicity. The conventional wastewater treatment available but it gives low efficiency and stability, also high cost required for process. In recent years, enzymatic wastewater technologies are use for wastewater treatment. Various enzymes from various microbes have been reported to play important role in wastewater treatment. Enzymatic wastewater treatment is more economical effective and eco-friendly. Enzymes remove recalcitrant pollutants by precipitation and transform to other value added product. By using the Immobilization of enzymes increase the mechanical and thermal stability of enzymes. The use of the enzymes in the case of harmful chemical reactions is extremely important for cleaner and greater technologies to save the planet.
