The developed CFD-based model has been used to study the velocity profiles of OBS. The model is very useful tool in view of the fact that the OBS is having complicated hydraulic patterns that always cause a high internal recycle flow or the cycling of mixed liquor throughout the system. The developed CFD model has also been used to assess the current operational performance that is related to aerations shaft of the OBS. To date, limited information is available on the use of CFD simulation for operational performance study. The CFD analysis performed in the research may enhance the use of CFD in this field. The CFD application in wastewater industries has expanded and the confidence level of using it has also increased. This research has also lead to more studies related to this field. All pros and cons of this research can be used as the guideline for a better CFD application in the related research. When further understanding is achieved in CFD-based process modelling, anyone working in this related field may possibly accomplish a better knowledge or experience to put forward possible development in the CFD models themselves.
