Abstract

A detailed research project is set up to validate a vortex separator overflow construction. In this vortex separator, collected sewer water enters radially from the sewer pipe in a cylindrical inner reservoir. The passage flow to the treatment plant is situated in the bottom centre, while the overflow passes a radial weir into an outer shell reservoir. In a laboratory model the removal efficiency of this overflow structure is identified for several hydrodynamic flow operation modes by recording sediment redistribution over the structure. As a result of these series of experiments on a model of a vortex separator overflow, the efficiency of this kind of construction is identified as a function of both hydrodynamic parameters and lay-out features. Doing so, the vortex separator is introduced as an alternative overflow constructio
