Assignee: RESEARCH COOPERATION FOUNDATION OF YEUNGNAM UNIVERSITY
Field: Chemical engineering (Chemistry)
Classification: CPC B  C  G | IPC B  G

Claim 0:
1. A fine particle separating apparatus comprising:
a first filter comprising a first mesh configured to separate 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 in the second region and configured to receive an effluent having passed through the first filter;
a third flow path connected to the second flow path and configured to discharge the effluent therethrough;
a fourth flow path connected to one side of the second flow path and mounted in the second region to allow at least a portion of the effluent flowing into the second flow path to flow therethrough into the first filter;
a fifth flow path mounted in the first region to receive the effluent discharged from the fourth flow path after the effluent passes through the first filter;
a reservoir receiving the effluent discharged from the fifth 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 fourth flow path.
