Separation performance of an 8 mm mini-hydrocyclone and its application to the treatment of rice starch wastewater

ABSTRACT The rice starch particles are difficult to separate from starch suspensions for its fine diameter. In this work, an 8 mm mini-hydrocyclone is designed, and its separation performance and potential for the treatment of rice starch wastewater is investigated. The capacities, total separation efficiencies of an 8 mm mini-hydrocyclone and a 10 mm mini-hydrocyclone are compared. The experimental results reveal that the total separation efficiency of the 8 mm mini-hydrocyclone is approximately 13% higher than that of the 10 mm mini-hydrocyclone. A total separation efficiency of 92.1% was obtained using a two-stage hydrocyclone separation process comprising two 8 mm mini-hydrocyclones connected in series. The research findings can be utilized to efficiently treat the rice starch wastewater.
