Abstract

Primary sedimentation tanks are structures of primary waste water treatment. Rectangular tanks are quite common in Slovakia although they are known to have some hydraulical problems resulting from their geometry. Furthermore, the inflow channel is almost exclusively oriented perpendicularly to the direction of the flow in these tanks. In this paper, we will show some of the problems caused by these factors, with the use of CFD simulations.
