QuenchGone21 Wastewater (QG21W) is the key to a new level of control in biological wastewater treatment plant operation! QG21W provides the ability to measure the active biomass population (cATP), stress levels (BSI), and suspended solids activity (ABR). By isolating the living population and eliminating all interferences, the operator can maximize efficiency and stability in any treatment process to prevent upsets, manage toxicity, streamline operations, and save money! Use QG21W in high-solids applications such as:

QG21W uses two parallel analyses on each sample to determine the health and activity of the active biomass population in a cooling water sample. QG21W test protocols provide three 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 provide the ideal basis for operational stability, optimization, and continuous improvement of a wastewater treatment process.
• Biomass Stress Index (BSI™) – represents the stress level experienced by the microbiological population. This quantity provides an early warning of impending process problems and stressful conditions (i.e. toxicity).
• Active Biomass Ratio (ABR™) – represents the percentage of bioreactor solids that are active microorganisms. Maximizing the ABR provides many benefits such as enhanced sludge quality and improved settling.

The QG21W kit also offers the optional Floc Bulking ATP (fbATP) add-on which offers the unique ability to predict the onset of bulking conditions well in advance of conventional laboratory techniques such as Sludge Volume Index (SVI).  This is made possible by screening a mixed liquor sample and extracting the ATP from the floc that is retained on the screen.  The higher the fbATP is relative to the Total ATP of the mixed sample, the greater the bulking potential.  As bulking floc begins to predominate, the fbATP test will reveal the deviation from baseline conditions immediately and thereby providing the basis for preventative action of a bulking incident.

How to Get Started

LuminUltra's test kits contain all of the consumable materials required to run their specified number of tests (Defined by the last 2 or 3 digits of the product code). To use these test kits, LuminUltra recommends one of the following equipment bundles:

• Field Kit & Luminometer (EQP-PAC): Field Case, Micropipettors, Kikkoman Lumitester.
• Bench Materials & Luminometer (EQP-BTM): Micropipettors, Kikkoman Lumitester, Test Tube Racks.
• Kikkoman Lumitester TM C-110 (EQP-LUK): Kikkoman Lumitester luminometer & accessories.

NOTE: LuminUltra’s test kits can be used with the majority of photomultiplier tube–based luminometers. Contact LuminUltra to confirm compatibility of your luminometer.

LuminUltra is sensitive to the needs of each individual customer.  Our expert staff can consult with you to determine the best means by which the data collected from our test kits can be integrated into your existing data management practices.  We have multiple software platforms and can even assist you to integrate ATP data directly into existing control systems, process historians, and data archives.

Getting started with QG21W is easier with direct training.  LuminUltra can supply you with on-site auditing and training services, web-based training, and one-on-one consultation to get your process improvement program off the ground.  Contact us today to learn more!

Test Kit Contents and Storage

When you receive your QG21W test kit, utilize the following guidelines for material storage.  Note that the quantity of each item listed below will depend on test kit size.

* Luminase^W shelf life can be extended to 6 months when frozen, or can be left at room temperature for as long as 3 weeks during routine use.  Note that the LuminaseW supplied in QG21W kits is NOT interchangeable with other forms of Luminase (i.e.  Luminase, Luminase Lite, and Luminase^XL).
** Materials are included as part of QG21W Bulking (QG21Wb-25) test kit only.
*** Pipette tips supplied in complete test kits are compatible with most Fisherbrand and Eppendorf adjustable micropipettors.
