Abstract
PURPOSE: To simply and cheaply dehydrate sludge without the use of a coagulating agent and pressurization process by means of filtration with the self-weight of active sludge.
CONSTITUTION: Microbes in sludge has some degree of coagulation force, so the coagulating force and gravity cause coagulation and settlement and result in some degree of clogging of the filter cloth 3 mesh, which are overlayed to form a space. Dehydration is performed through this space by capillary action. Therefore, the mesh size of the filter cloth 3 is selected to the maximum that allows filtration depending on the quality of sludge. To prevent fluid pressure of the sludge from acting on the filter frame 5 at the bottom face, water is sprayed from porous spray holes 2. The quantity of sludge being inlet is controlled by a regulation valve 1.
