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. (C) 2001 Elsevier Sci
