Abstract: In Turkey, municipal solid wastes are primarily disposed in landfills. The infiltrated water in the landfill affects the chemical composition of leachate. The filtration, adsorption, dissolution, precipitation, ion exchange, and biochemical processes occur between the compacted clay soil and leachate. In this study, batch and continuous reactors are used to inveatigate permeability and adsorption of compacted clay soil. The clay soil, obtained from the Kemerburgaz-Odayeri landßill area on the European side of Istanbul, is put through standard and modified proctor compaction tests. The effects of Total Phosphorus (TP) and Total Kjeldahl Nitrogen (TKN) in the influent and effluent have been analyzed to determine the treatment capability for batch and continuous reactors of the compacted clay soil. The results of the per- meability measurements using leachate show that the permeability in the compacted clay soil associated with the contamination is slightly increased. Removal efficiencies of TP in clay soil were obtained as 72% for standard compaction and 77% for modißied compaction in continuous reactor. Also, TKN in clay soil was obtained as 60% for standard compaction and 81% for modified compaction in continuous reactor. Optimum adsorption time of TKN was 5 hours in batch reactor.
