Abstract
An inclined sedimentation acceleration apparatus includes an inclined part having a plurality of inclined flow paths through which raw water flows, and side plates disposed on both sides of the inclined part. An upper ridge part of the inclined part is disposed at a height different from that of an upper ridge part of the side plate. Suspended solids are less likely to accumulate on an upper surface of the inclined sedimentation acceleration apparatus.
