Experimental Investigation of Leachate Treatment Using Low-Cost Adsorbents

Abstract

The aim of the project work is to treat the landfill leachate before disposal. The necessity for landfill leachate treatment is a requisite to reduce the environmental related to impact related to municipal solid waste land fill. If leachate is directly disposed into environment it creates serious problems on the surrounding soil, ground water aquifers and nearby surface water. Therefore great attention has been directed towards new techniques based on physico- chemical process, and heavy metals removal using low cost materials as filter media with down flow reactor. Leachate generation is a major problem for municipal solid waste (MSW) landfills and causes significant threat to surface water and groundwater. Leachate can be defined as a liquid that passes through a landfill and has extracted dissolved and suspended matter from it. Leachate results from precipitation entering the landfill from moisture that exists in the waste when it is composed. Different consider while deciding for an appropriate treatment process. This paper presents the results of the analyses of leachate treatment from the solid waste land fill. Key Words: : Leachate, physico-chemical process, landfill, precipitation, solid waste, Municipal Solid Waste (MSW).
