Abstract
Trihalomethane formation potential (THIVIFP) and water quality of leachate from municipal solid wastes landfill site was investigated for 4 years. Calcium and manganese ions, which determine hardness of water, decreased enough in the leachate treatment process; however, high concentrations of sodium, potassium, and chloride ions were detected in the discharged water. Bromide ion concentration in the discharged water was 2-3 orders higher than in a reservoir for drinking water, which may increase bromate production during ozonation. THMFP in the discharged water consisted of mainly bromide compound, and was 335μg/l on an average and 1, 530μg/l at a maximum.
