Experiencing These Challenges?


Distribution system regrowth & nitrification: 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.

Field maintenance including line and tank flushing, line break assessment, and new installations: 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.

Treatment monitoring including biological and membrane filtration: 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.

Source water quality including algal blooms: 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.

Why does this happen?

For water distribution: In water distribution systems, the bulk of the microorganisms are usually associated with the surfaces (sessile microorganisms) rather than those that are free-floating in the water (planktonic microorganisms).

Microbes tend to form thick deposit layers known as biofilms on tank and pipe surfaces in order to establish a favorable ecosystem for growth and for protection against disinfectants. This leads to microbially-induced corrosion (MIC) and many other challenges.

The key is the ability to precisely locate contamination hot spots quickly so as to facilitate rapid action.

For water treatment: Traditional regulated measurements for microorganisms can only detect a portion of all waterborne microorganisms. On top of that, the technologies behind these test methods can date back to 130 years ago and will take as long as weeks to answer a simple “yes or no” question as to whether or not a specific microorganism is present. During this lag, problems can become exponentially worse.

In addition to health concerns from pathogenic microorganisms, water quality management has significant implications on infrastructure integrity. Membranes, pipelines and storage tanks can all be affected by microbial growth. The best defense against microbial proliferation and premature equipment failure is early detection.

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 the 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.
