Abstract

The article deals with the problems of thin-layered (lamella) module`s clogging in the sedimentation tanks at sewage treatment plants and possible ways to solve them. The purpose of this work is to improve the structure of the lamella module using mathematical modeling in ANSYS FLUENT to analyze the effectiveness of its performance. A horizontal sedimentation tank with a lamella module with flat plates is chosen as research object. The paper presents a comparison analysis of simulation results of particle deposition process in a lamella module with flat plates and in a module with an improved structure. Finite element analysis in ANSYS FLUENT shows that the improved lamella module type has higher particle deposition efficiency than the ordinary type.
