Industrial Process Water and Chemical Applications (QG21I)
How and Where is this Test Kit Used?
|
 |
QuenchGone21 Industrial provides the means to accurately monitor and control total microbial growth in any industrial process water stream. LuminUltra’s advanced reagent system provides accurate, repeatable, and interference-free results in high-solids, medium-biomass applications such as:
|
|
|
-
Raw Wastewater
-
Specialty Chemicals
|
This kit can also be used in the following applications and industries:
QG21I uses two parallel 1-minute analyses on each sample to determine the health and activity of the living microbial population within any process water sample. These test protocols provide two pieces of valuable information:
-
Cellular ATP (cATP™) – represents ATP from living microorganisms, and therefore is a direct indication of the living population. Once target thresholds for cATP are established, cATP results can be used to manage biocide treatments.
-
Biomass Stress Index (BSI™) – represents the stress level experienced by the microbiological population. This quantity is very useful in monitoring biocide treatment efficacy.
QuenchGone21 Industrial is capable of measuring down to 20pg ATP/mL, which is roughly equivalent to 20,000 organisms per mL. cATP and BSI measurements provide the means to manage, troubleshoot, and optimize biocide treatment systems in real-time.
An effective routine monitoring program using QuenchGone21 facilitates continuous improvement and maximizes product quality!

Using ATP to Measure Living Biomass in Wastewater Bioreactors
Because they are the engine that drives biological wastewater treatment, it is critical to closely monitor the quantity and quality of microorganisms in bioreactors. Learn how ATP measurements give a more accurate biomass indicator than conventional measurements.

Using ATP Measurements to Perform Wastewater Process Audits
Much can be learned in a short time by utilizing ATP measurements to audit wastewater treatment processes. Learn how ATP measurements were applied to uncover certain characteristics at an Eastern Canadian pulp and paper manufacturer’s effluent treatment process.

|
Using ATP Measurements to Troubleshoot Bioreactor Stress Mechanisms
Bioreactor upsets are often preceded by conditions that cause biomass stress. Oftentimes, these stress mechanisms are complicated and difficult to interpret. Learn how ATP measurements provide the missing link in determining the mechanisms behind stress and offer the ability to reduce or eliminate future occurrences.

Early Warning of Upsets and Toxicity in Wastewater Treatment
Using routine ATP testing to monitor toxicity at the front end of a wastewater treatment process can provide the early warning necessary to prevent process upsets. This study provides examples where customers were able to link bioreactor stress and its resulting downstream effects to influent toxicity.

Using the Biomass Growth Index to Assess Wastewater Source Quality
Most wastewater treatment bioreactors accept wastewater from a multitude of sources whose quality can vary over time. The Biomass Growth Index is a useful bench-scale procedure for assessing source quality in a short period time through harnessing the abilities of accurate ATP measurements.
