Project Name : Removal of Heavy Metals from Waste Water
Theme Name : Environmental Issue and Concerns
Objective: To create awareness among people about the hazards of toxic heavy metal present in water and its removal from natural resource.
Abstract: An increase in population initialing rapid industrialization was found to consequently increase the effluents and domestic waste water into the aquatic ecosystem. Heavy metals are major toxicants found in industrial waste water. They may adversely affect the biological
treatment of waste water, conventional methods for the removal of heavy metals from waste waters are often cost prohibitive hence, there is a need for cheap methods for effluent treatment.
Heavy metals are widely used in textile industries and significant losses occur during the manufacture and processing of textiles, and these lost heavy metals are discharged in the effluent. Adsorption of heavy metal is a new technology for treatment of waste water containing different types of selected heavy metals In this study adsorbents like carbonized
rice husk, activated rice husk, tea waste, coconut husk, coconut shell bean leaves, bark or many other organic substance available as agriculture waste are investigated as viable material for treatment of Pb, Cd, Ni, Cr, Zn, etc. present in industrial waste. Experiments revealed a relative ability of all these organic substances in removing these heavy metals.
The reason of choosing this topic was to make potable water (devoid of heavy metals) available for the masses. The current technology in the market to remove heavy metals from the water is the RO and UV filters. These filters are cost prohibitive and also have their drawbacks. Our aim is to make the people aware about our self developed cost – effective filter which require materials that are eco-friendly, readily available and in expensive.
Let‟s hope our drive can make every human being free of toxic metals and its hazards.
