ABSTRACT
The goal of this paper is the analysis of a primary settling tank at the waste water
treatment plant in Humenné, SK. The analysis is performed with the use of a
mathematical model from the ANSYS CFD software package, ANSYS Fluent. The
article discusses hydraulic problems in the inlet zone of the settling tank, which are
caused by the specific shape of inlet zone for the perpendicular wastewater inflow.
Several states of the settling tank were calculated to simulate different shapes of the
inlets, and analyses possible solutions to these problems.
