Removal of Heavy Metals from Industrial Effluent using Electrogravimetric Technique

Heavy metal pollution due to industrial effluents poses significant environmental and health risks. To address this issue, various techniques have been employed, among them electrogravimetric technique has emerged as a promising solution, effectively removing heavy metals through electrochemical precipitation. This review critically evaluates the technique’s principles, advantages, and applications, highlighting its effectiveness in removing most common heavy metals from various industrial effluents. The technique has demonstrated impressive removal efficiencies of above 90% under optimal operating conditions, as evidenced by case studies. However, challenges such as scaling up, electrode corrosion, and competing ions must be addressed to enhance its feasibility
