Abstract
There is provided a method for cleaning a ceramic filter which can shorten an operation time required to clean the ceramic filter. The method for cleaning the ceramic filter includes: reducing a pressure of a space on a secondary side of the uncleaned ceramic filter, while supplying a cleaning medium to a space on a primary side of the uncleaned ceramic filter, thereby passing the cleaning medium through the ceramic uncleaned filter, so that the uncleaned ceramic filter is cleaned.
