Comparison Of Geosmin And 2-Methylisoborneol Removal By Conventional Ozonation And Co-Treatment Of Potassium Ferrate And Peroxymonosulfate, Zhaoran Xin
Electronic Thesis and Dissertation Repository
Geosmin and 2-methylisoborneol (2-MIB) are two common compounds that cause taste and odor problems in water. This study compares geosmin and 2-MIB removal from water by conventional ozonation, ferrate and peroxymonosulfate (PMS) oxidation processes. The effects of initial O3 doses, H2O2/O3 ratios, and pH on the removal efficiency of geosmin and 2-MIB were evaluated for ozonation. The addition of H2O2 and alkaline condition increased the removal efficiency by ozonation. A Box-Behnken Design was applied to study the influence of ferrate and PMS dosage and pH on the removal of geosmin. It …
