Abstract
The experiments which study the decomposition of azo dyes such as acid red 1 and acid yellow 23 by using ozonation, photolytic ozonation and photolytic hydrogen peroxide oxidation have been studied in laboratory sized reactor and pilot scale reactor to determine the reaction rate constants.
The rate constants and mass transfer coefficients were obtained by a series of experiments of varying complexity. A reaction kinetic model which describes the contemplated experiments was developed and exercised using the Rosenbrock Hillclimb Optimization Algorithm with the Forth-Order Runge-Kutta method. The effects between different hydrogen peroxide dosages and pH level were also analyzed.
In order to demonstrate the feasibility of the O3/UV and H2O2/UV processes in wastewater treatment, CSTR (constant flow stirred tank reactor) experiments were also conducted. Comparing the theoretical data and experimental data in this CSTR process, the application of this kinetic model and rate constants in wastewater treatment process was confirmed.
