Abstract

PURPOSE:To easily remove the dust accumulated on the surface of a filter in back-washing by forming the layer holding the powder of cleavable material in the surface layer of at least one surface of porous ceramics filter. CONSTITUTION:The filter layer holding the powder 34 of cleavable material is formed in the surface layer of at least one surface of a porous ceramics filter 12. As for the cleavable material, an ore of cleavability, such as saltpeter, mica and graphite, of <=40-60mum average particle diameter is used. As for the method by which the powder of cleavable material is held in the surface layer of filter, the method in which the gas containing the powder is flowed so that the powder is caught, or the method in which the powder is rubbed into the filter surface is used. The powder of such a cleavable material is formed to have scaly shapes, and the powder entered the pores of filter is difficult to flow out even in back-washing while the permeability of filter is secured.
