An Evaluation of the Technical Feasibility of the Packed Tower Advanced Oxidation Process for the Removal and Destruction of Contaminants from Water

Abstract : This final report describes the research work done to investigate the behavior of a packed column contactor as an ozonation reactor for destruction of organic contaminants in groundwater treatment. Both a laboratory and pilot-scale column have been used during experiments to gather scale up information for such a system. The columns have been operated in either cocurrent and counter current mode using trichloroethylene (TCE) at low ppm levels in water as the contaminant. The TCE removal and destruction has been measured as a function of gas to liquid (G/L) ratio, contacting pattern, and ozone concentration. Using the experimental results and literature information, mathematical modeling has been done to describe and simulate the system behavior.
