摘要：Leachate is a concentrated liquid that originates from solid waste dumping sites. Releasing of leachate tothe environment without treatment pollutes the soil, surface and ground water. In this study leachate is treated withAlum and in conjunction with polyelectrolyte to remove heavy metals. The Alum with Polyelectrolyte has shownhigher removal efficiency of heavy metals. Alum of dosage 1 g/l and combination with 0.3g/l of polyelectrolyteproduced optimum results in removal of Cadmium, Chromium and Nickel removal efficiencies being 92.4%, 77.3%and 80.1% respectively at pH 7.
