Overflow Rate of High – Rate Settlers

After a concise overview of the theoretical principles of high-rate settlers proposed by Yao, the parameters are defined that enable a comparison between the overflow rate of various high-rate settling systems and of conventional settlers A system of parallel plate settlers, a system of circular tube settlers, and a system of square conduits settlers are analyzed On the basis of the performed analysis, the overflow rate coefficient, Cr, as a function of high-rate settling system, angle of inclination of the settler and the relative length of the settler, is defined The Cr value is less than 1 and more than 0 As to the value of the overflow rate coefficient, it is shown that the overflow rate of high-rate settlers is Cr-1 times less than that for conventional settlers.
