Aquatic ecosystems support various life forms. Discharge of contaminants into water bodies is a matter of concern all over the World. Thus, the waste water released from different sources should be purified at source. This project aims to clean waste water by flowing through different layers of corn cobs like long pieces of corn cobs, small pieces of corn cobs, powdered corn cobs, activated charcoal made from corn cobs and fine sand. This is a cost-effective and simple technique. This is useful for immobilizing the contaminants in domestic and industrial effluents, and in ponds, reservoirs and water tanks.
