2011 – NSERC Engage Grants Program- CFD analysis of Liquid Flow Pattern and Floc Particulates in a New Multi-Environment Wastewater Treatment System


This project demonstrated the application of a newly developed numerical technique based on computational fluid dynamics (CFD) analysis to investigate the hydrodynamic properties of the BioCAST multi-environment wastewater treatment bioreactor, including liquid flow pattern, liquid circulation velocity and particulate trajectory in response to variations in the geometry and operating conditions of the bioreactor. The hydrodynamic properties of the bioreactor were determined during laboratory experiments and exhibited agreement with the results of numerical computation. The developed numerical approach proved to be reliable for the assessment of bioreactor’s performance and presents an alternative approach for the optimized design of the multi-zone bioreactors during the treatment of wastewaters at full-scale operations.
