High rate settler
WebIt appears that a high-rate settler system can handle considerable overloading without serious reduction in its turbidity removal efficiency. A settler with its flow through velocity less than 0.6 fpm (18.3 cm/min) tends to perform better than that with a higher flow … WebOn the basis of the performed analysis, the overflow rate coefficient, C, as a function of high-rate settling system, angle of inclination of the settler and the relative length of the settler, is defined. The CV 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 ...
