I believe that we value what we know. We use scales, models and frameworks to help us understand complex matters and materials. Review the conceptual models and categorization efforts of Daniel Defoe, Charles Darwin, Anders Celsius, John Smith Elgin Marbles, Seamus Heaney, Tycho Brahe, Captain Bligh, and my favorite, Rear Admiral Francis Beaufort, author and developer of the Beaufort Wind Scale.
Energy efficiency, as defined in wastewater treatment, is using less energy to provide the same service. It can be expressed as energy dollar savings by replacing older, inefficient motors.
Like Hans and Franz from the classic Saturday Night Live skit, we’re ready to “Pump you up!” with training and exercises to conquer operator certification exams. Your trainer, wastewater consultant Dan Theobald (“Wastewater Dan”), presents his latest round of Math Solutions.
Although the city of Bozeman, Montana’s stormwater system has been silently producing front-page news for decades, it has typically only flowed into the spotlight because of an incident or an emergency.
This January, a national leader emerged with a plan to shake up the status quo, touting a “business” approach to rectify historic “inadequacies” of our system. And we should all be on board with the plan, because it means potentially great things for the water and wastewater industry.
Controlling system biomass is a key component to meeting consistent, high quality effluent in the activated sludge process. Of the available strategies for activated sludge process control, maintaining a constant sludge age or solids retention time (SRT) is a very effective tool.
Positive displacement water meter with Sensus® Electronic Register+™.
Sensus accuSTREAM meters consist of three basic components: maincase, measuring chamber and sealed register. Maincases (including the bottom plate) are made of composite material with externally-threaded spuds. Registers are housed in a bonnet of synthetic polymer. Measuring chambers are of Rocksyn®, a corrosion-resistant, tailored thermoplastic material formulated for long-term performance and especially suitable for aggressive water conditions. The accuSTREAM can be installed horizontally.
The Water Network Optimization Suite by Schneider Electric provides water utilities an overview of the entire water distribution network in real-time and in “future-time” by enabling operators to be forewarned of critical situations in the network so that immediate actions to prevent or mitigate service disruptions can be taken with enough lead time.
AccuGrid protective grating provides a strong, interlocking, non-skid surface on top of tube settler and trickling filter media. As a cost-effective alternative to other walkway systems, it covers the entire media surface for complete access to the distribution system. AccuGrid also improves safety by eliminating trip hazards through its surefoot tread design and locking tabs that maintain panel alignment.

For managing chlorine feed rates, automated chlorine analysis has always offered advantages over manual grab samples and feed adjustments. Today, chlorine analyzers connected to cloud-based systems for integrated instrument, data, and process management are bringing new continual-sampling insights to water and wastewater treatment plants (WTPs/WWTPs).
While accurate instrument readings are important to water treatment plant (WTP) and wastewater treatment plant (WWTP) operators, having deeper understanding of plant operations is even more valuable. Here’s how intelligent networking capabilities are giving plant operators better understanding and control over their processes by enhancing instrumentation operation, data sharing, and maintenance management.
As the sheer number of pipelines crisscrossing the country continues to increase, there is an urgent need to ensure pipeline infrastructure safety. The age of many of the pipelines and the number of different products flowing makes this a challenging prospect. Now, new technology has been developed that meets the need for reliable protection that complies with regulatory requirements while eliminating false alarms.
Most estimates of global mean sea-level rise this century fall below 2 m. This quantity is comparable to the positive vertical bias of the principle digital elevation model (DEM) used to assess global and national population exposures to extreme coastal water levels, NASA’s SRTM. CoastalDEM is a new DEM utilizing neural networks to reduce SRTM error. Here we show — employing CoastalDEM — that 190 M people currently occupy global land below projected high tide lines for 2100 under low carbon emissions, up from 110 M today, for a median increase of 80 M.
South Africa’s towns and cities could be rendered more resilient to natural disasters if municipalities understand the likely impacts of climate change and build these impacts into their disaster management strategies for the future.
There are a variety of reasons for wanting accurate flow metering — e.g., billing purposes, precise proportioning of chemical injections, and other process flow decisions. That is why highly accurate mag meters are so popular in many applications. Now, new lightweight, corrosion-resistant mag meters provide the same advantages as plastic piping for harsh environments and flows that cover all the bases…and acids.
For many water-distribution workers and managers up to their elbows in muddy trenches and SCADA data, the drumbeat for ‘Big Data’ probably fades to background noise when dealing with immediate leaks and losses on the front lines. Don’t throw the baby out with the bathwater, however. Many answers we truly want are probably accessible through current water distribution data. We just need an easier way to wring them out.
With a continuous flow of air required to maintain dissolved oxygen (DO) levels, the last thing a wastewater treatment plant (WWTP) operator wants is to come up short of the volume needed to sustain good microbial growth. With today’s ready availability of high-efficiency rental blowers, losing blowers to unplanned downtime or being unable to test new aeration systems before commissioning are no longer the threats they once were.
Today, a group of leading labor unions and associations announced "Moving America Forward: a 2020 Presidential Candidate Forum on Infrastructure," convened by United for Infrastructure, to be held over President's Day Weekend 2020 on the campus of the University of Nevada, Las Vegas (UNLV).
Frank Rittel knew there had to be a safer, more effective way for El Paso Water employees to communicate at work sites other than using hand signals and shouting. The solution came to the utility Heavy Equipment Trainer Supervisor when he watched an episode of the television show “Gold Rush.”
American Water, the largest publicly traded U.S. water and wastewater utility company, held its companywide AmerICANs in Action! Month of Service employee volunteer event in September.
