The performance of UV reactor which is used in water treatment is strongly affected by UV fluence rateand water flow in the UV reactor. Therefore, CFD tools are widely used in designing process of UVreactors. This paper describes the development of a computational fluid dynamics (CFD) methodology thatcan be used to calculate the performance of open channel type UV reactor used in wastewater treatmentplant. All computations were performed using commercial CFD code, CFX, by considering three dimensional,steady, incompressible flow. The Eulerian-Eulerian multi-phase method were used to capture the water-airinterface. The MSSS model, provided by UVCalc3D, was used to calculate the UV intensity field. Thenumerical predictions and calculated UV Dose were compared with experimental dataset to validate the CFDmethodology. The reactor performance based on MS2 log reduction was well matched with measurementswithin 6%. |
