<p>There is disclosed a ceramic filter formed with less membrane formation times and having a water permeation performance and a separation performance. There is also disclosed a regenerating method of the ceramic filter, capable of inexpensively regenerating the ceramic filter in a case where the filter deteriorates. A ceramic filter (10) includes a porous base member (11) formed of a ceramic porous body, a carbonaceous membrane (12) formed on the porous base member (11), and an inorganic separation membrane (e.g., a silica membrane (1)) formed on the carbonaceous membrane (12). As the inorganic separation membrane, instead of the silica membrane (1), a titania membrane, a zirconia membrane, a zeolite membrane or the like may be used. In a regenerating method of the ceramic filter (10), the deteriorated ceramic filter (10) is thermally treated to remove the carbonaceous membrane (12) and the silica membrane (1) from the porous base member (11), then the carbonaceous membrane (12) is formed on the porous base member (11), and the silica membrane (1) is formed on the carbonaceous membrane (12).</p> |
