EN The following work discusses the phenomenon of solid particle settling, presents the characteristics of suspensions and the fundamentals of sedimentation. The velocity of a solid particle free settling has been characterized as well as the sedimentation velocity. Additionally, the paper tackles upon the issue of a liquid stream purification and wastewater purification, where various devices used for the purpose have been characterized, such as horizontal settling tanks, swirl settling tanks and Dorr settling tanks. A special attention was paid to the characteristics of swirl settling tanks, their advantages and potential applications. Also, the outcomes of the research performed to develop the said devices have been described. The aforementioned research considered the influence from the advanced settling tank design components introduced over the purification efficiency of liquid streams from heavy and light fractions, such as inlet or outlet connectors or a partition inside the device. The damming of liquid and the values of local resistance factors have been evaluated as they differ in various technical solutions for settling tanks. The research allowed to determine the construction marked with the highest efficiency in purification of liquid stream, which gives us a possibility to develop the option for analyses with regards to the devices of this type.
