Abstract

Ozone oxidation of wastewater’s organic matter in a counter-flow-packed-column was analyzed. Two steps were considered in the oxidation process, the first involved the ozone mass transfer from gas to liquid phase and, the second was the oxidation reaction itself. Packing height and shape effects on the oxidation process were estimated using a model based on basic mass transfer relationships and an irreversible pseudo-first order kinetic reaction. Wastewaters with high organic matter contents, expressed as chemical oxygen demand (COD), were analyzed so the model was simplified considering that high reaction rate occurred and the mass transfer controlled the process. It was observed that COD concentration profile throughout the column depended on: temperature and operating pressure; ozone solubility in the wastewater; feed gas ozone concentration; wastewater’s organic matter content; and both gas and liquid flow rates. The effect of different random and structured column packing materials on oxidation process was also analyzed. Evaluated Packing materials were: 1" Pall rings; Norton Intalox 2T; Mellapak 250Y; and, the best results were achieved with Sulzer BX.
Keywords: ozone oxidation, packed-column, simulation, wastewater, chemical oxygen demand.
