Modeling and Optimization of Process Parameters by Taguchi Method: Degradation of Phenolic Compounds by UV/H2O2/TiO2 Process

Shilpa Nandwani, Arvind Kumar Mungray and Mousumi Chakraborty

In this study, Taguchi method was used to identify the several factors that may affect the percentage degradation of phenol and p-chlorophenol in wastewater in a UV/H2O2/TiO2 system. The percentage degradation of phenol and p-chlorophenol was greatly influenced by factors such as pH, cycle time and initial concentration of the organic pollutant. By using orthogonal experimental design and analysis technique, the UV/H2O2/TiO2 system performance can be analyzed with more objective conclusion through only a small number of simulation experiments. Analysis of variance (ANOVA) was carried out to identify the significant factors affecting the response and the best possible factor level combination was determined through. Finally, a regression model for percentage degradation of phenol and p-chlorophenol has been developed, as a function of system parameters. It was found that a UV/H2O2/TiO2 system decomposition of the organic pollutant were highly dependent on cycle time followed by pH of aqueous solution. The optimal settings of highest percentage degradation of phenol and p-chlorophenol in wastewater were also determined.
