ANALYSIS OF THE EFFICIENCY OF THE CSO CHAMBER AT EXTREME WASTEWATER FLOW
Abstract
Combined sewer are among the most important objects of a unified sewerage network and therefore high requirements are placed on these objects, whether from hydraulic, hydrological, hygienic or constructional requirements. Their main function, ie hydraulic, is to divide the inflow at the time of torrential rains into a flow continuing to the WWTP and a flow that is relieved from the OK to the recipient. Another important function of relief chambers is related to pollution. Some chamber designs can successfully capture larger solids with rakes, but this purification is not possible with suspended and dissolved materials. Therefore, from the point of view of the protection of recipients, it is necessary to design relief chambers so that the dilution ratio of sewage and rainwater at the time of above-limit flows is in accordance with legislative requirements. The paper deals with the analysis of the existing relief chamber using mathematical simulations. The software used to create the mathematical models is Ansys Fluent.
