Document Type and Number:
WIPO Patent Application WO/2022/014537
Kind Code:
A1
Abstract:
In the present invention, the concentration power of a cleaning solution is increased. A membrane filtration system comprises: a filtration body (32) for filtering, through a membrane, a cleaning solution (W0) from a scrubber that purifies exhaust gas from a ship's engine; and a cleaning means for cleaning the filtration body (32). The cleaning means executes cleaning by switching between: standard cleaning in which a pressurized liquid is supplied to the filtration body (32) and then discharged from the filtration body (32); and pulse cleaning in which the filtration body (32) is pressurized and then depressurized.
