Classification: CPC B  C  G | IPC B  G

Claim 14:
15. A fine particle separating apparatus comprising:
a first filter comprising a first mesh separating fine particles contained in sludge according to size, the first filter having a first region and a second region with the first mesh placed therebetween;
a first flow path mounted in the first region and configured to allow the sludge to flow therethrough into the first filter;
a second flow path mounted at both ends thereof in the second region configured to receive an effluent from the first filter and configured to allow the effluent to flow therethrough back into the first filter;
third flow path mounted in the first region configured to receive the effluent from the second flow path;
a reservoir receiving the effluent discharged from the third flow path; and
a first pump configured to create a flow of the effluent,
wherein the first mesh is rotatably mounted on the first filter, and
wherein the separating apparatus is constructed such that fine particles contained in the sludge flowing through the first flow path that fail to pass through the first mesh are forced to flow into the reservoir by hydraulic pressure of the effluent flowing into the first filter through the second flow path.
