Design of Leachate Treatment Plant for Adharwadi Dumping Waste

Abstract

Generation of municipal solid waste (MSW) is increasing due to urbanization, commercialization, and rising population. This result in leachate generation from MSW landfill and dump side. Leachate from dumpsite is the major environmental   problem as it causes surface water pollution, ground water pollution and land pollution. Leachate is defined as a liquid that passes through a landfill and has extracted dissolved and suspended matter from it Raghab et al. 2013. Toxicant from leachate adversely affect the surface water and groundwater resources. Therefore, leachate treatment is necessary. In the present study, leachate sample were collected from Adharwadi dumping ground, Kalyan. It has been observed that leachate flows into Ulhas creek, thereby causing contamination. The main objective is to treat leachate and reduce the level of toxicants which is turn will reduce the contamination of Ulhas creek. Leachate includes various harmful heavy metals, organic and inorganic chemical as well as pathogens.
