Water treatment plant (WTP) and wastewater treatment plant (WWTP) operators are increasingly supporting better decision-making by leveraging digitalization capabilities available through instrumentation and plant management systems. Successful adoption of digitalization starts with identifying the right balance of tools (i.e., web-networked instrumentation) and systems (i.e., analytical data management software). Maximizing the value, however, is as much about exercising a mind-set of efficiency as it is about tracking raw numbers.
Ashley Valley Water & Sewer Improvement District (AVWSID) serves rural county residents who live outside the city of Vernal, Utah.
When selecting a new analyzer for your plant, there are many different features to consider. One of those is the choice of how the instrument will be calibrated, namely between an inexpensive manual calibration and a more complex automatic calibration method. (To be clear, we will define automatic calibration as a feature that involves no operator intervention at the instrument.) Factors that influence this choice are financial, process, staff levels, and personal preference. Let’s explore each of those.
The biggest flood in decades roared through the Village of Johnson City, NY, one day in September 2011, and the water department lost everything, including their office, which was submerged in several feet of water. Working with Neptune Technology Group, Johnson City began installation of its new Neptune meters, along with E-Coder®)R900i™ combination solid state absolute encoder/RF meter interface units.
Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown.
Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
This is the second installment of a three-part series examining wipes in the waste stream. The first installment looked specifically at the growth of disposable wipes usage within the last decade. Now we’ll look at the public outreach campaigns and some of the ways pump manufacturers are adjusting their technology to try to reduce or prevent wipes-related clogging.
Prolagos, an AEGEA company, provides water and sanitation services for five municipalities in the state of Rio de Janeiro, Brazil. The concession covers the famed Lakes Region (Região dos Lagos), where seasonal populations fluctuate from nearly 400,000 to more than 2 million.
The majority of the water in the city of Simi Valley, California, is provided by Ventura County Waterworks District 8, serving approximately 26,000 metered connections — 22,000 of which are now read by Neptune’s R900® System.
A food processing company in northern California has a small wastewater treatment plant to treat its wastewater before releasing it back to the local municipality.
A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.
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.
Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.
Rapidly produce FREE engineering designs for activated sludge wastewater treatment plants.
Built for both non-technical (basic inputs) and technical (detailed inputs) users, our WWTP Design Generator automatically integrates decisions and calculations from each engineering discipline (process, mechanical, civil, architectural, electrical) to create a preliminary design for a wastewater treatment plant (WWTP).
What used to take several weeks of work involving experts and engineers from multiple disciplines can now be completed within six hours using Water Online’s groundbreaking WWTP Design Generator.

It’s increasingly obvious to me that the gap in the general understanding of technology is continuously increasing with those that are not working in the space every day. I am referring to industrial technology versus the general consumer technology market.
This heated debate continues to rage on in boardrooms, online forums, and tradeshow floors around the world. It pits SCADA teams, seeking to maximize system uptime, against IT departments, working to keep their systems secure. What follows is a very brief overview of why water and wastewater utilities choose to allow remote access and what steps should be taken to minimize the risk.
Global demand for power and water is accelerating — and the Middle East is no exception. A burgeoning population combined with multiple industrial diversification programs is fueling a boom in power and water projects. During the first three quarters of 2017, about US$30 billion of major power contracts and US$20 billion of water projects were awarded across the region. In 2018, the figure is looking more like $60 billion with the two sectors combined.
VTScada software helps Jamaica National Water Commission adopt world-class monitoring and control system.
While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
