Scaling Laws for Hydrodynamic Separators
Publication: Journal of Environmental Engineering
Volume 123, Issue 10
Abstract
This paper reviews the way in which scaling protocols for solid-liquid separators have developed in the last 25 years and shows how modelers of hydrodynamic separators can be faced with a dilemma when choosing the appropriate dimensionless groups used for scaling. Laboratory results from a series of geometrically similar hydrodynamic separators (operating with no baseflow) are presented and correlations between efficiency and several nondimensional groups (conventionally used to compare the performance of solids liquid separators) are discussed. It is concluded that the use of single dimensionless groups such as Froude number has limited applicability in predicting full-scale separator performance. However it is shown that a hybrid protocol can successfully predict the efficiency of solids removal from full-scale hydrodynamic separators over a wide range of flow conditions.
