Abstract: An inclined mesh panel type filtering apparatus capable of easily removing suspended solids from water. In a conventional apparatus, a filtration fabric is contaminated from use even when it is cleaned by a brush unit or a cleaning unit, and is almost clogged, in the course of one to two years after being put into operation, to such an extent that scale is not even removed even by additional manual cleaning. Thus, the entire apparatus should be disassembled to replace the filtration fabric with a new one or exchange an entire filter drum. This problem is resolved by the inclined mesh panel type filtering apparatus that can be continuously operated for a long time in which a filtration panel formed with fine openings having a typical size of 0.2 to 1.2 mm is not clogged and does not require high-pressure cleaning-water or air showers that consume high energy.
