Food, chemical, pharmaceuticals, industry having offers a wide range of applications for centrifugal separation by the way of mechanical. Now a days, the process industry having high capacity continuous plant, they are adding some re-agents, mixing catalyst, percipatation. After they are setling to remove two specific gravity materials. For setling method take more time, and high losses. The same immiscible liquid through passing. De-canters, Centrifugal Disk Separator, Tubular Centrifuge. As per application the two liquid separated by Mechanical rotation separation liquid continuously.
