Abstract
Waste water contamination is ever increasing problem which the whole world is now facing. Industrial waste constitutes the major source of metal pollution in natural water. The surface water also contaminated by various industrial activities. When the effluent from various industries like Tannery Industry, Textile Industry, Electroplating Industry, etc., is discharged into the water bodies, it will causes the water pollution. The global population is on the rise, increasingly concentrating in urban centers. This pattern is particularly pronounced in developing nations, where urbanization is expected to swell by over 2.1 billion individuals by 2030. Tamarindus indica fruit shells have found application in agriculture to bolster productivity under heavy metal stress. They present a low-cost, effective alternative for chromium removal from tannery wastewater, which originates from industries like tanneries, textiles, and electroplating. Utilizing Tamarindus indica fruit shell waste and Mangifera indica seeds as adsorbents is a strategic move, considering their potential in filtration, detoxification of contaminated water, effluent treatment, and wastewater adsorption. This study focuses on removing chromium from tannery wastewater using Tamarindus indica fruit shell powder and Mangifera indica seeds. Both materials exhibit notable chromium removal capabilities, with Tamarindus indica fruit shell achieving 59.78% and Mango seed achieving 98.58% removal efficiency at an optimal pH of 5. Maximum removal efficiency occurs at 15 minutes and 120 rpm for time and speed variations, respectively, with equilibrium reached once maximum efficiency is achieved for both parameters.
