Abstract

A filtering apparatus for processing liquids includes filtering element which is provided outside a clean liquid tank so that the clean liquid discharged through an outlet provided at the bottom of a filter tank is stored in a clean liquid tank. It is therefore possible to prevent processing powder from falling in the clean liquid tank and contaminating the clean liquid during the work of changing the filtering element and easily perform the work of changing the filtering element while maintaining the amount of processing liquid contained in the filtering element at the minimum level. It is also possible to easily perform the maintenance of the filtering element and remove the need for a maintenance space around the filter for processing liquids.
