Abstract

PURPOSE: To remove contaminants, e.g., oils, etc., from polluted water while flowing out the polluted water by combining netted structures not to overlap the meshes of the netted structures in a method of preventing the diffusion of contaminants.
CONSTITUTION: Netted structures N1 and N2 are combined in such a way that the mesh portions of one netted structure are not overlapped with those of the adjacent netted structure. When using the netted structures as a pollution preventer, Von Karman's vortex flow is formed in the back side of the netted structure N1 when polluted water flows in the direction of arrows, whereby contiaminants in the polluted water are removed. Then, in the same way, contaminants in the polluted water are removed even by the next netted structure N2.
