Rapid sand filtration is one of the most widely used and extensively investigated unit-operations in the water supply systems. Nevertheless, the fundamental removal mechanism of suspended particles in the sand filter is poorly understood at present. 　　　In this paper, the auther presents an approximate distribution function of suspended particles removed in the filter. Then, in order to compare the function with the data obtained in the experiments, to pursue M^* and S_0 in the function, and, in addition, to understand more clearly the removal mechanism of suspended particles, experiments were performed by the use of equipments in Fig. 1. As a result, it was found that the data were fit for the function to a high degree. The other observations are also presented.
