LEAD REMOVAL FROM INDUSTRIAL WASTEWATER: A COMPREHENSIVE REVIEWKALYAN KUMAR YERNAGULA, SHIVAM KUMAR GAUTAM AND SHASHANK GARGAbstract Lead is a poisonous metal whose prolific use has turned violent on the ecosystem and harmed peopleâs health in the world. WHO established guidelines for lead tolerable consumption levels, which are 10 g/l in drinking water and 0.5 g/m3 in the air. Itâs a multi-system toxin that affects the nervous, haematological, cardiovascular, and renal systems. Lead has no biological role in the human Body. In this review, we will mainly concentrate on lead recovery from wastewater using a variety of strategies including chemical techniques such as chemical precipitation, coagulation, and conjugate materials that exhibit different colours based on lead concentrations. Electrochemical methods has shown a robust performance and capability to adjust to variations in the influent composition and flow rate, degrading a wide range of contaminants. Most importantly biological processes, such as bioleaching, biofiltration, and biosorption, are particularly environmentally sustainable, reliable, and cost-effective. These are the techniques which are highly employed for removal of lead from wastewater in modern world. |
