The report deals with evaluation of the performance of Landfill Leachate treatment using natural adsorbents. Inorganic and organic pollutants present in the Leachate continue to pose major problems in receiving water bodies and to the environment. To overcome such problems, natural adsorbent materials are used to minimise their negative environmental impact. In order to find out the effective natural adsorbents for the treatment of landfill leachate, two locally available low cost adsorbents such as Coir Pith and Coconut shell Activated carbon were analysed by using fixed bed Vertical column adsorption Studies. The study also determine the efficiency of the adsorbent materials with time to remove contaminants from semi aerobic stabilized landfill leachate. For this study, one vertical column reactors of same dimensions such as 10.5 cm Diameter, I meter Length were fabricated providing adsorbents depth of 60 cm from the bottom and the columns were packed with pre-treated neutralized Adsorbents Coir Pith and coconut shell Activated carbon respectively. The semi aerobic landfill leachate taken for this study were analysed for its initial characteristics and noted. It was then allowed to down flow through the vertical column from the top at the flow rate of 0.5 ml/min. The treated outlet collected at the interval of 7 days from the outlet Nozzle provided at the bottom of the column and their characteristics were analysed and compared with the initial.
