A model to determine oxygen mass transfer coefficient in bioreactors

Buch

The objective of this paper is to present an experimentally validated mechanistic model to predict the oxygen transfer rate coefficient (Kla) in aeration tanks for different water temperatures. Using experimental data created by Hunter and Vogelaar, the formula precisely reproduces experimental results for the standardized Kla at 20 0C, comparatively better than the current model used by ASCE 2-06 based on the equation Kla20 = Kla. (O)(20-T) where T is in 0C. Currently, reported values for O range from 1.008 to 1.047. Because it is a geometric function, large error can result if an incorrect value of O is used. Establishment of such value for… Mehr
