With electricity consumption being a primary operating cost in water treatment and wastewater treatment, steps taken to optimize energy use are critical. Saving energy is more than just an on/off decision. Monitoring and managing energy use — from analyzing pump curves, to reducing non-revenue-water leaks, to scheduling operations around premium-rate windows — is essential. Fortunately, the payback potential can be impressive.
When the Village of Romeoville underwent a major upgrade to their SCADA system, they also decided to move to the latest version of the monitoring & control software that they had used successfully for many years. This version included features designed specifically for the water/wastewater industry. In this article, a former Head of the Water Department (*) explains why the utility continues to push for the latest HMI version and how this helps them overcome many of the issues related to maintaining a long-running SCADA system.

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.
Many municipal water treatment plants utilize Ozone Treatment Systems to produce clean water for residential and industrial users. While all the various types of water treatment systems have their advantages and disadvantages, Ozone (O3) systems provide excellent disinfection and avoid some of the chemical byproduct problems experienced with the use of chlorination.
“I know that (blank) is good for me; I just haven’t gotten around to doing it yet!” Most of us can fill in that blank with any number of tasks — modifying diets, exercising, or monitoring commercial and industrial (C&I) water meter accuracy at our largest utility accounts. If that last item is still on your “to-do” list, here are several good reasons why you should do it and how to make it happen soon.
Cone meters have been around for decades, since the mid-1980s. They are frequently confused with other technologies for a number of reasons.
Utility managers are facing increasing financial and sustainability pressures regarding water loss throughout their systems. An American Water Works Association (AWWA) white paper titled The State of Water Loss Control in Drinking Water Utilities notes that “all utilities incur inefficiencies, or losses, in both supply- and customer-related functions of their operations.”
Real-time contaminant detection, featuring a network of sensors throughout the distribution network, is poised to revolutionize the water industry.
Process, instrument and plant engineers are challenged continuously by productivity and plant operating efficiency objectives as well as ensuring plant compliance with an ever expanding list of regulations.
The industrial world is awash with data and new information from sensors, applications, equipment, and people. But the data is worthless if it is left untouched or not used to its full potential to gain insights and make better decisions.
Digitalization of the municipal water treatment industry is fragmented today, with instrumentation, control, and automation technologies mixed with manual operational activities. Such infrastructures can be detrimental in cases of hydro-geological events, such as severe storms and earthquakes. The good news: When natural disasters strike, digitalization can help get municipal water treatment back online quickly and effectively.
Siemens offers to our customers the ability to both make process measurements and to remotely monitor the activity and health of that instrumentation without the need for SCADA systems or other expensive process control room products. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement as well as valve control, we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.
One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
Hach LDO® technology improves the efficiency of pharmaceutical plant’s wastewater treatment process, helping to protect the environment and the community.
Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.
Compliance and consistent high quality are two of the key goals within the beverage industry. Hach® provides support for these goals through comprehensive analyses of water and beer.
There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.
In the world of industrial automation, the talk is centered around “industrial internet of things” (IIoT). With buzzwords like “Industry 4.0”, “IoT”, “digital twin”, “cloud computing”, “artificial intelligence”, “machine learning”, and “deep learning”, it is difficult for automation engineers and business managers to determine how to implement these new technologies.
It took some time for computational fluid dynamics (CFD) to find its way to the water industry, but now that it has, a primer is warranted to understand its application.
The movie and sports term has infiltrated the business world and has important implications for the water/wastewater industry.
The journey toward intelligent water can be expedited with eight key steps — a guideline for gliding through the Digital Water Adoption Curve.
Ammonia removal is a key metric for assessing wastewater treatment facility performance. This is because ammonia contributes to aquatic life toxicity. Furthermore, nitrogen, along with phosphorus, is a driver of receiving water eutrophication. Eutrophication, which simply is an over-enrichment of nutrients, can be detrimental to environmental and public health. It can result in harmful algae blooms, dissolved oxygen depletion, fish kills, and other damaging impacts.
