Abstract
In Turkey, municipal solid wastes are primarily disposed in landills. The iniltrated water in the landill affects the chemical composition of leachate. The iltration, 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 landill area on the European side of Istanbul, is put through standard and modiied proctor compaction tests. The effects of Total Phosphorus (TP) and Total Kjeldahl Nitrogen (TKN) in the inluent and efluent have been analyzed to determine the treatment capability for batch and continuous reactors of the compacted clay soil. The results of the permeability measurements using leachate show that the permeability in the compacted clay soil associated with the contamination is slightly increased. Removal eficiencies of TP in clay soil were obtained as 72% for standard compaction and 77% for modiied compaction in continuous reactor. Also, TKN in clay soil was obtained as 60% for standard compaction and 81% for modiied compaction in continuous reactor. Optimum adsorption time of TKN was 5 hours in batch reactor.
