The modeling of a fountain photocatalytic reactor with a parabolic profile

A dimensionless mathematical model for a novel, thin film, slurry fountain photocatalytic reactor for water or wastewater treatment is presented. The model extends the applicability of the horizontal water fountain model prev iously presented to include water fountains with a parabolic profile. The m odel was developed using parameters that can be easily estimated for real s ystems. The model was successfully validated with experimental results from the photocatalytic oxidation of indigo carmine dye in a pilot-scale reacto r using titanium dioxide (TiO2) as the photocatalyst.
