Abstract

Leachate landfills are defined as the aqueous effluent generated by rainwater percolation through wastes, biochemical processes in waste cells, and the inherent water content of wastes themselves. Leachates may contain large amounts of organic matter (biodegradable, but also refractory to biodegradation), They contain non-biodegradable organic matter and nitrogenous compounds. There are different methods for the treatment of composting leachate. Parameters dictating which method to choose include the leachate’s quantity and quality, required treatment amount, and economic issues. Therefore, posttreatment of composting leachate using ozonation was considered the main objective of this study. In the ozonation process, the amount of ozone for treating the leachate in optimum condition was determined to be 0.65 gr/h. In this process, a maximum color removal of 85% was attained after 60 minutes of ozonation at pH 9.

Keywords: Leachates, landfill, Ozone, Color removal.
