Continuous filtering process with rotating disk cleaner and a filter therefor

Abstract From the Canadian patent

A continuous filtering process in which a violent turbulency of fluid to be filtered is caused in a filter tank through which the fluid is continuously flowed by rapidly, rotating rotators which are arranged in the filter tank so that the surfaces of the rotators are faced to the surfaces of filter media provided to hollow filter disks with small intervals such as three or five millimeters therebetween. Such violent turbulency of the fluid rapidly disperses concentrated fluid from on the surfaces of the filter media so that the clogging of the filter media or the formation of concentration polarization layer is not caused substantially, thereby continuity of a filtering operation being much …
