Biochemical Methods for Water Purification

Prompt amplification in industrialization and population has resulted in the heightened discharge of polluted water containing heavy metals, dyes, pigments, and other organic pollutants into freshwater systems, which upsets the quality of water, causes biotic menaces and harms the health of the human beings. Particularly heavy metals and dyes are harmful to aquatic life and are not biodegradable and must be extracted from wastewater before discharging into freshwater. Treatment of polluted water using various physicochemical methods such as electrolysis, chemical precipitation and flocculation, adsorption, reduction, ion-pair extraction oxidation, and electrochemical treatment is expensive and is associated with larger sludge production. Thus biochemical approaches are a contemporary area of research fascinating the researchers around the globe.
