Abstract
A photoreactor has been set up to study the feasibility of ozone and ultraviolet radiation for treating pollutants in water. Phenol, 2,4-dichlorophenol, and 2,6-dichlorophenol were chosen as pollutants in this study.
The reaction kinetics mechanism has been postulated to be consisted of ozone decomposition, oxygen activation by UV, and reaction of pollutant with ozone, UV, and activated species. The corresponding reaction rate constants were found, using Rosenbrock optimization program, from four different experiment sets --- reaction of pollutant with ozone; reaction of pollutant with UV; reaction of pollutant with O2/UV; reaction of pollutant with O3/O2/UV.
The steady state outlet concentration in CSTR were predicted, using the postulated reaction kinetics mechanism and the optimized reaction rate constants. The steady state approximation were applied for the concentrations of intermediates. Results showed that the experimental values of outlet concentration at the steady state in CSTR were 15% higher for phenol and less than 5% higher for 2,4- and 2,6-dichlorophenols than the predicted values.
In near future, it is expected that more specific reaction kinetics mechanism will be developed. Accordingly, the economic feasibility of ozone and ultraviolet radiation will be more accurately predicted.
