| Abstract: | A perforated spinning disc ozone contactor is described with reference to its use as an absorber with simultaneous chemical reaction. Greatly enhanced mass transfer coefficients kL are measured whilst simultaneously maintaining low ozone loss. Comparisons of kL and volumetric coefficient, kL a values, are made with more conventional packed or bubble columns. Acetic acid, 2-propanol and 4-nitrophenol, representing a wide reactivity range, are used to elucidate the applicability of rotating contactors in effluent treatment. It has been possible to study the effects of surface activity on mass transfer with subsequent reaction and to generate design data for the next generation of rotating contactors. |
