Hydraulic equations for vortex separators dimensioning

摘要

The paper presents a set of hydraulic expressions developed to design vortex separators. These devices are used for gravitational removal of suspensions from wastewater. Methods for vortex separators dimensioning found in the literature could still be improved. Measurements of tangential velocity and liquid residence time conducted on a laboratory vortex tank allowed the authors to formulate a mathematically simple velocity field model of an essential technical advantage. Then, equations describing suspended particle motion in the separator were derived. Finally, a technical procedure for hydraulic design of vortex separators was developed.
