The requirements for the UK Water Industry to meet recently published NRA guidelines concerning the performance of CSO structures are of great concern to the UK Water Industry. This project proposes a novel design of CSO structure and seeks to develop a widely applicable mathematical model to predict CSO performance.A recently completed study (Saul et al 1994) has compared the performance of end weir and side weir CSO chambers and dynamic separators in the form of a vortex chamber and a swirl type hydrodynamic separator. The results of this study highlight that a swirl chamber has good performance at low flows and high ratios of the continuation flow to inflow whereas the vortex chamber performs well at high inflow rates and low construction to inflow ratios. The objective of this study is therefore to develop a novel design of CSO chamber to combine the desirable performance features of both these types of chambers. This will be carried out scientifically by using the existing large scale laboratory chambers to establish the flowfield by LDA velocity measurement and the track of individual particles by flow visualisation to establish design criteria for the new CSO design. One such novel chamber will be constructed and tested within the laboratory concurrently, the results from the experimental study will be used to enhance and verify the existing FLUENT 3D mathematical model. The results of a pilot study (Saul and Svejkovsky) have confirmed the potential application of the particle tracking routines in the FLUENT model to describe CSO performance and subsequently the model will be used to optimise the performance of the novel design of chamber. The model will then be applied to the more conventional designs of CSO chamber and will be widely applicable within the UK Water Industry.
