Abstract

During the design of leachate treatment plants at Japanese landfill sites, the main examined design parameters have been leachate treatment plant capacity and raw leachate quality. However, the scientific basis for characterizing raw leachate quality has been less robust, especially for the Cl− concentration. This characterization is usually based on the precedent of other operating leachate treatment plants. However, regarding the quantity and quality of leachate at landfill sites, there is a close relationship between these parameters and Cl content in waste cells or the waste cell placement method, and these parameters depend on the landfilling method, dilution zone (no dumping area), and the quantity of leachate. Based on the landfill shape, dilution zone (no dumping area), waste cell placement method, and property of the waste cell, the Landfill Cell Model can predict leachate concentration. In this research, we used a process of calculating leachate treatment plant capacity and the Landfill Cell Model together to investigate an early method for stabilizing landfill and dilution zones. The results revealed the possibility of characterizing the optimal leachate treatment plant capacity by balancing leachate reservoir capacity and the predicted Cl− concentration of raw leachate in landfill.
