Abstract

The spread of urbanization drives problems which distort the urban water cycle as a form of flood disaster and pollutant loads. When it comes to pollution, a lack of information on the load and characteristics of pollutants has led to insufficient reduction measures. Thus, this study discusses filtration by different types of filter media as an initial treatment to reduce pollutant loads. This study examined the effectiveness of the filtration method with different types of filter to control micro-particles from rainfall runoff water. The particle size and characteristics of pollutants were investigated. In addition, the characteristics of filter media in the filtration process, such as head loss, treatment efficiency, and changes in particle size distribution were also analyzed by lab-scale experiments. This study suggested the best filtration material to treat surface wash-off pollutants based on the results of various experiments on the treatment of real samples collected from roads and combined sewers. The results and discussions shown in this study may be useful as basic information for appropriate design and operating parameters of filtering facilities to control rainfall runoff pollutants caused by urban storms.
