Prevent Upsets Before It's Too Late - What Your Biomass Can Tell You, If You Look
The benefit of ATP monitoring was not fully understood until January 2009 when a significant toxic upset event occurred. This paper will discuss how the ATP testing along with other routinely collected plant data revealed the onset of the 2009 upset, helped identify the source of the problem, assessed the degree of damage done, and facilitated troubleshooting in the aftermath of the upset. Rather than relying on TSS or VSS measurements that contain many components other than living cells, ATP monitoring isolates the living population from dead biomass, inert solids, and other interferences. This 5-minute test shows the active population's response to stimuli (good and bad), and therefore gives operators the ability to immediately detect changes in the process and determine the source and severity of toxic events.
