Abstract

A new aspect for evaluating the effects of the tank hydraulic characteristics and wastewater quality on the overall efficiency of a liquid solid separation system J. Mihopulos, H.H. Hahn Institut fur Siedlungswasserwirtschaft (Sanitary Engineering), University of Karlsruhe, Germany ABSTRACT Traditionally chemical dosing for an improvement of liquid-solid separation is designed and operated more or less independently of the actual reactor's geome- try and hydraulic characteristics. The wide-spread use of jar tests in day-to-day operations illustrates this fact. There is not much information available on the quality of floes emanating from coagulation units relative to the separation pro- cess' requirements. And if such information were available the interaction of sus- pensa with the flow structure in any given reactor still needs to be determined. The paper describes the results of systematic investigations on the interaction of specifically coagulated suspensions (und
