Mitigation of Biological Process Upsets Caused by Organic Inhibitors
Publication: Journal of Environmental Engineering
Volume 115, Issue 5
Abstract
A laboratory investigation was conducted to determine the relative importance of the physiological state of the reactor population and biomass concentration on mitigating short-term toxic shocks. The studies were conducted using 2-chlorophenol (2-CP) as a model toxic compound. Both factors were identified as having a probable benefit in reducing toxic inhibition caused by transient events of 2-CP. Of the two, the inhibition rate was more significantly influenced by the physiological state of the organisms (i.e. ϴc) than by biomass concentration. Consequently, prediction of toxic inhibition as a function of biomass concentration without regard to changes in cell physiological state may lead to erroneous conclusions.
