Oxygen Transfer Efficiency

In aerated ponds, oxygen is generally supplied through either diffused or mechanical aeration means. Surface transfer and bubble transfer both contribute significantly to oxygen transfer in a diffused aeration system. In the present study, a liquid-film-forming apparatus (LFFA) is successfully developed on a laboratory scale to improve considerably the surface transfer via the unique liquid film transfer technique. The experimental results show that the volumetric mass transfer coefficient for LFFA alone is found to be as much as 5.3 times higher than that for water surface and that the total volumetric mass transfer coefficient for the liquid film aeration system increases by 37% in comparison with a conventional aeration system. Additionally, by tuning finely the structural parameters of the LFFA, it can also lead to high dissolved oxygen (DO) water with the DO percent saturation greater than 90%. More importantly, this result is accomplished by simply offering a single-pass aeration at a depth as shallow as 26 cm. As a result, the objective of economical energy consumption in aerated ponds can be realized by lowering the aeration depth without sacrificing the aeration efficiency. It is noteworthy that the data presented in this study are acquired either numerically or experimentally.

Inactivation Efficiency

This study presents results for the use of UV radiation and a liquid-film-forming device (LFFD) for disinfection of water. Escherichia coli was used as a model microorganism for examining the bactericidal performance of UV. Bacterial inactivation was conducted in a LFFD with various condition of UV dosages, air flow rates, and initial bacterial concentrations. Combined UV/LFFD treatments resulted in a greater inactivation efficiency than those for the UV treatment alone. Combined treatment with UV (UV dosage = 3.020×10-20 kJ/m2, initial bacterial concentration = 1.1×105 – 2.2×105 CFU/mL, and room temperature) and LFFD (air flow rate = 2400 L/min) caused 89% inactivation in terms of the bacterial load. In contrast, when the UV treatment was used, only 29% of the E. coli load was inactivated. These findings suggest that the combined UV/LFFD treatments could provide a promising method for water disinfection.
