ABSTRACT:
A ceramic filter includes a porous base member formed of a ceramic porous body, a carbonaceous membrane formed on the porous base member, and an inorganic separation membrane formed on the carbonaceous membrane. According to a method for the ceramic filter for reuse, the deteriorated ceramic filter is thermally treated to remove the carbonaceous membrane and the inorganic membrane from the porous base member, then the carbonaceous membrane is formed on the porous base member, and the inorganic membrane is formed on the carbonaceous membrane.
