Abstract |
The mass transfer of oxygen from air bubbles to water is of considerable practical importance in treatment of sewage by bio-oxidation and in many industrial fermentation processes. The cost of this operation is comparatively high because large quantities of air have to be compressed to the pressure of the system and dispersed into small bubbles. To obtain more information on this action it was proposed to conduct a preliminary investigation of the effects of three homologous series of organic compounds on the size of air bubbles, mass transfer coefficient, and on the interfacial areas of air-water dispersions. The series of compounds selected for investigation were the mono- and di-carboxylic acids and aliphatic alcohols. This was done in order to determine the possible effects of the type of the compound and its molecular size. Some tests on carboxylic acids, obtained in our previous work, are also discussed in the report. (Author Modified Abstract) |
