The merits of the sonophotolysis as

The merits of the sonophotolysis as a combination of sonolysis (US) and photolysis (UV/H2O2) are
investigated in a pilot-scale external loop airlift sonophotoreactor for the treatment of a synthetic
pharmaceutical wastewater (SPWW). In the first part of this study, the multivariate experimental design
is carried out using BoxeBehnken design (BBD). The effluent is characterized by the total organic carbon
(TOC) percent removal as a surrogate parameter. The results indicate that the response of the TOC
percent removal is significantly affected by the synergistic effects of the linear term of H2O2 dosage and
ultrasound power with the antagonistic effect of quadratic term of H2O2 dosage. The statistical analysis of
the results indicates a satisfactory prediction of the system behavior by the developed model. In the
second part of this study, a novel rigorous mathematical model for the sonophotolytic process is
developed to predict the TOC percent removal as a function of time. The mathematical model is based on
extensively accepted sonophotochemical reactions and the rate constants in advanced oxidation processes.
A good agreement between the model predictions and experimental data indicates that the
proposed model could successfully describe the sonophotolysis of the pharmaceutical wastewater.
