Optimization of closed underflow mini-hydrocyclones for separating sand from well water by two indices of mass efficiency and cut diameter using the Taguchi method: a case study of Mashhad, Iran

Abstract In this study, the Taguchi method was applied in order to design experiments and optimize performance of mini-hydrocyclones by closed underflow for sand removal from well water. To hydrocyclones, two indices, mass efficiency cut diameter, were used. The first index analysis results showed that under optimum conditions, overall solids will be up 98.4%. An diameter data illustrated predicted about 12.7 μm, while estimated at 16.3 μm conditions. actual values determined 97.2 ± 1.1% 14.5 0.7 respectively, hydrocyclone manufacturing on basis use traditional estimation models such as Plitt, modified Luz, so on, which are mining mineral processing, diameters 7.9, 8.4, 8.2, 0.45, 2.33 respectively. This represented these not suitable predict with underflow. Further investigation revealed only scale-increasing model could a 15.4 μm.
