PROBLEM TO BE SOLVED: To provide a method and an apparatus for washing the filter medium of a solid-liquid separator capable of effectively washing clogging not only on the surface of the filter medium but in inside of its surface. SOLUTION: The method and the apparatus for washing the filter medium of the solid-liquid separator which has the filter medium consisting of inorganic materials, such as ceramics and metals is characterized in that the surface of the filter medium is washed with gaseous ozone by diffusing the gaseous ozone and bringing it into contact with the surface of the filter medium. The clogging of the filter medium is effectively prevented by oxidizing and decomposing foreign matters with the powerful oxidation of the gaseous ozone, which is diffused from the lower outside or inside of the filter medium.
