Abstract:
Distribution chambers are widely used in various processes, where there is a need to split the main stream to feed parallel process trains at the same discharge rate. Uneven distribution of the flow may cause uneven load to the biology, which is originally designed to a certain capacity, thus the overall performance of a wastewater treatment plant could deteriorate. In this paper a cost-effective evaluation methodology is presented, with which the performance of a distribution chamber can be determined. Numerical fluid dynamic simulation with turbulence modelling was applied to calculate the flow field and the flow rate of each sub-stream. As a result, the inappropriately designed chambers could be re-design prior the actual operation.
