- Abstract
- The performance of UV reactor which is used in water treatment is strongly affected by UV fluence rate and water flowin the UV reactor. Therefore, CFD tools are widely used in designing process of UV reactors. This paper describes thedevelopment of a computational fluid dynamics (CFD) methodology that can be used to calculate the performance of openchannel type UV reactor used in wastewater treatment plant. All computations were performed using commercial CFD code,CFX, by considering three dimensional, steady, incompressible flow. The Eulerian-Eulerian multi-phase method were used tocapture the water-air interface. 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 CFD methodology. Thereactor performance based on MS2 log reduction was well matched with measurements within 6%.
