Water treatment operators balance their time between a wide range of responsibilities. On any given day they could be preparing chemicals, performing maintenance and miscellaneous repairs, reviewing data, collecting samples, and running a variety of tests. In balancing these competing demands, some important duties might not get the time required to truly maximize benefits. One… Read More
New details about SARS-CoV-2, the virus that causes COVID-19, seem to emerge daily. Expanded Testing Requirements A concerning but important finding is that viable virus can be recovered from pre-symptomatic individuals several days before symptoms appear – as well as from asymptomatic individuals. This highlights the need for effective surveillance and contact tracing programs, which include identifying and testing asymptomatic and pre-symptomatic individuals, to prevent further spread. While contact tracing will always require clinical testing for… Read More
A Synopsis on Legionella Legionella, the bacteria responsible for causing Legionnaire’s disease, is one of the most significant sources of waterborne disease outbreaks in the U.S. Investigations by the CDC have indicated that many cases could have been prevented through better water management. We’ve previously written about Legionnaire’s disease and how ATP testing can be… Read More
What are ‘Bug Bottles’? As highlighted in a previous blog, microbes can cause a range of microbiological problems in oil and gas extraction processes. By controlling microbial growth, operators can prevent issues such as: plugging, flow-reduction, reservoir souring and costly microbially influenced corrosion. Various methods are available for monitoring levels of problematic groups of bacteria,… Read More
Last month I attended the American Water Works Association’s Annual Conference and Exhibition in Denver. There was a lot to learn with so many technical presentations, workshops, and trade show booths, so I figured I would highlight some of my key takeaways from the conference. 1. Top Trend Given the size of the conference,… Read More
In a previous post, we described some of the ways that LuminUltra’s 2nd Generation ATP testing can be used to help operators and field technicians by delivering rapid microbiological water quality data for immediate action. In this entry, we look at how it can be used to help supervisors and managers better allocate their resources,… Read More
For those familiar with 2nd Generation ATP testing, it’s clear that the luminometer is a critical piece of equipment in the testing procedure. It allows us to quantify ATP by measuring the light produced through the reaction of ATP and the luciferin-luciferase based enzyme – just like the way light is produced in a firefly’s… Read More
The Quench-Gone syringe filter is included in our ATP test kits for some methods. Learn more about about what they do.
From the editor: This is the 14th post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic. Pseudomonas is a genus of Gram-negative, rod shaped, non-spore forming bacteria. More than 190… Read More
Microorganisms can wreak havoc in industrial processes in a number of ways – from slime formation that causes paper breaks and excessive downtime in papermaking facilities, to costly recalls of spoiled final product. Consequently, an effective microbiological control program, which includes accurate and reliable monitoring, is critical for maintaining an efficient process and final… Read More
