Title:
FILTERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/070548
Kind Code:
A1
Abstract:
The purpose of the present invention is to solve a problem in which a washing function is degraded by the washing of a tubular-type filter membrane. When a liquid to be filtered is filtered by being pressure-fed into a UF membrane tube 15 in a tubular-type membrane separation device 10, a sponge ball is made to flow inside the UF membrane tube 15 by the liquid to be filtered, so that deposits attached to the inner surface of the UF membrane tube 15 are cleaned out by the sponge ball. To ensure that a passageway 125 for the liquid to be filtered moving inside the tubular-type membrane separation device 10 is longer than the length from the end on one side of the tubular-type membrane separation device 10 to the end on the other side, the passageway 125 is curved inside the tubular-type membrane separation device 10. A reception tool 18 is provided for receiving the sponge ball, which has moved inside the UF membrane tube 15 and come out from a liquid outlet 118 of the tubular-type membrane separation device 10, while allowing a concentrate to pass through. The reception tool 18 has a detachable cap for enabling the received sponge ball 17 to be taken out and replaced.
