Abstract

The present invention discloses an apparatus for dehydrating a filter press. The apparatus for dehydrating the filter press of the present invention is characterized by the ability to relieve the clogging of a sludge casing by foreign substance produced in the process of dehydrating sludge, thereby providing stable dehydrating performance and preventing damage or alteration of the sludge casing due to pressure to guarantee a longer life.
