SLUDGE FILTRATION APPARATUS AND FILTER ASSEMBLY THEREOF

摘要

A sludge filtration apparatus has a sludge tank configured to store sludge and at least one filter assembly. The filter assembly includes a filtration membrane for filtering the sludge and a pipe insertable in the filtration membrane to supply air to a secondary side of the filtration membrane for dislodging the sludge from the filtration membrane. The pipe has a plurality of holes for discharging gas, namely air, to an area in which the filtration membrane inclines downwardly with the secondary side thereof. The sludge filtration apparatus can prevent thickened sludge from remaining in an upper portion of the filter assembly.
