Popis: The performance of a small hydrocyclone is examined experimentally for solid particle separation from water. The cyclone has an inner perforated cylindrical tube connected to the overflow orifice, and a conical cylinder is inserted into the underflow orifice to adjust the underflow flux. Two types of the inner cylinder were tested: the one has 50% void fraction of the perforated surface and the other has 61.2%. The glass bead was used as a solid particle whose average diameter is 4.84 μm. It is found that the hydrocyclone with the inner perforated cylinder shows better performance: When the cyclone has 50% void fraction of the perforated cylinder, the decrease of pressure loss is about 30% and the increase of separation efficiency is about 15% compared with the conventional cyclone. The higher void fraction of the inner cylinder produces higher performance.
