Abstract: A continuous filtering process and apparatus therefor in which a violent turbulence of fluid to be filtered is caused in a filter tank through which the fluid is continuously flowed. The turbulence is caused by rapidly rotating rotators which are arranged in the filter tank so that the surfaces of the rotators face the surfaces of filter media provided in hollow filter disks. A small interval such as three or five millimeters occurs between the rotators and the filter disks. Such violent turbulence of the fluid rapidly disperses concentrated fluid from the surfaces of the filter media so that the clogging of the filter media or the formation of a concentrated polarization layer is substantially prevented. Continuity of the filtering operation is therefore increased even when filter media having very fine perforations therethrough are employed.
