Experiencing These Challenges? Here's why.
Once biofilms are established, they can protect the microbial community and consume disinfectant residual. This means that a major barrier to regrowth has been removed and therefore the overall risk of microbial proliferation is increased significantly. In chloraminated systems, nitrifying bacteria pose an even greater challenge because they cannot be grown using traditional total plate count methods. Due to its rapid feedback, all-encompassing measurement, and portability, 2nd Generation ATP monitoring provides a far superior tool than traditional microbiological tests to solve this problem since it can be deployed in the field.
When field service activities are conducted, technicians have plenty of tools at their disposal but microbiological field tests have never been a reality until now. 2nd Generation ATP tests enable field technicians to assess water quality during flushing and maintenance activities to know when sufficient flushing has been done, as well as when additional attention is warranted. This not only minimizes wasting of water, but also eliminates return site visits when the job was prematurely ended.
Microbiological content in biofilter media can be directly analyzed to assess the treatment potential of the filter. When used together with other key operating parameters, the impact on the biomass of things like filter run time, backwash frequency, pre-treatment, and nutrient supplementation can be assessed.
There are also opportunities to optimize membrane filtration efficacy. Not only can permeate quality be assessed in minutes, but an overall assessment of biological fouling can be done in minutes by comparing feed, permeate, and reject streams. Maintenance schedules can be adjusted accordingly, thus maximizing treatment efficacy as well as the useful life of filter modules.
Dealing with algal blooms can be very challenging but the first step in dealing with the problem is an effective monitoring solution. ATP monitoring in source water can reveal the early onset of biological proliferation which can give users a heads-up of an emerging algal bloom. With results available in minutes, action can be taken much more quickly than what would be possible if traditional testing was used as the primary indicator of biological content.
How can 2nd Generation ATP® monitoring help to mitigate these challenges?
Microbiological threats are best addressed in their early stages of growth. If microbes aren’t detected quickly, they can’t be properly treated – giving them ample opportunity to grow and quickly get out of control. In recognition of this fact, the EPA’s Revised Total Coliform Rule (RTCR) has emphasized the time-sensitivity of microbial contamination detection.
The real-time, accurate quantification of total microorganisms provided by LuminUltra’s solutions afford your team the ability to pinpoint the problem area within a system, apply treatment, and quantify the efficacy of this treatment or action within a matter of hours compared to days or weeks with traditional methods.
This rapid feedback enables the expedient and proactive adjustment of system operations to ensure that localized problems do not evolve into major problems. Plus, LuminUltra’s solutions are able to quantify all of the microorganisms in any given water sample – including difficult-to-grow microorganisms such as nitrifiers and corrosion-causing sulfate reducing bacteria!
Using LuminUltra’s solutions as a means to characterize the overall threat offers the ability to mitigate threats in near real-time, while follow-up tests involving specific culture-based methods for targeted microorganisms can be performed to validate control mechanisms and guard against specific microbiological threats such as E. coli, Legionella, Pseudomonas, Naegleria and other pathogens.
How can you realize immediate cost savings?
LuminUltra’s solutions can help you achieve substantial improvements in manpower efficiency, overall product quality and instant economic benefit in areas such as:
- Flushing optimization – Turbidity and disinfectant residual testing are important to monitor during flushing but do not provide information relating to microbiological cleanliness. The addition of 2nd Generation ATP monitoring gives you the ability to determine how much flushing is enough to get the job done without sending samples to a laboratory. As such, you are able to gain immediate savings of water as well as excessive time typically spent by site technicians and laboratory staff.
- Storage Tank and Distribution System Audits – On-site assessment of water quality to troubleshoot regrowth equates to substantial time savings and the ability to employ a much more proactive approach. Problems can now be identified, sourced to their root cause, and solved in a matter of minutes.
- Optimization of membrane filter and reverse osmosis systems – Comparing the real-time test results from inlet and outlet enables on-the-spot assessment of membrane fouling. This can be used to guide maintenance programs in order to extend membrane life.
What is the return on investment?
Savings can be realized immediately through drastically reduced time needed for field service. Besides troubleshooting or routine testing taking much less time, a considerable amount of water (and operator time in the field) can be saved by optimizing flushing cycles during line break repairs, new installations, and routine seasonal clean-outs. In addition to avoiding over-flushing, under-flushing can also be prevented which would otherwise require a return trip into the field to complete the job later. Operational improvements have provided a typical payback period for the first year at 9 months and as short as 4 months in each year thereafter.

Recommended Test Kit
Quench-Gone Aqueous (QGA™)
Using a single analysis, Quench–Gone Aqueous (QGA) provides a rapid and interference–free determination of total microbiological concentration in any filterable water sample with a wide detection range. Use this test kit to perform source-to-tap surveys and characterize complete systems, identify areas of concern, and validate corrective action – all in the same shift!
The QGA test kit is designed for testing Low-Solids Water Samples:

Aurora Water (Aurora, CO) has been using LuminUltra’s Deposit and Surface Analysis test to measure and monitor Adenosine Triphosphate (ATP) in the biofiltration process at the Binney Water Purification Facility (BWPF) since April 2012. This easy to perform test allows BWPF staff to quickly determine ATP levels on the biofilter GAC during start-up of the processes, as well as during routine operation.
In addition, it has enabled the operations staff to establish baseline expectations for seasonal variations in the biofilters. The data obtained from the LuminUltra ATP test is routinely used, in conjunction with other monitoring parameters, to ensure the proper operation of the biofiltration process at BWPF.
