When I first came to Trihedral, I was surprised to learn that voice modems were still widely used in the HMI and SCADA industries. Though the days of wedging your phone receiver into a foam cradle are long gone, the name still conjures up the sounds of chirps, bleeps, and bongs they make as they translate analog information into digital. As high-speed networks became our preferred method of web surfing, the use of this technology has steeply declined.
In recent years, the debate about which technology is best suited for level monitoring and open channel monitoring (OCM) applications has taken some traction. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and OCM applications in the water industry. The counter-argument is that radar technology is more effective because it is more robust and accurate than ultrasonic technology.
The City of Eden Prairie, Minnesota recently updated its data management processes at the water treatment plant, with a goal of increased efficiency for everyone from operators to management. The Eden Prairie Water Treatment Plant draws from a groundwater supply to serve a population of 63,000 people, with a total of 18,000 water user connections. The plant primarily uses lime softening for treatment.
The Villoresi Channel, located north of Milan, was designed with the main purpose of agricultural irrigation while providing water to the city of Milan. The paths running along the canal were also used for recreational purposes and cross through some of the most beautiful natural parks in Lombardy.
The Ypsilanti Community Utilities Authority (YCUA) employs a total of 30 mixers in its aeration tanks as part of an anoxic nutrient removal process, and the mixers were failing. The mixers were old, inefficient, and starting to fail, so YCUA elected to replace them with Flygt 4320 mixers. Read the full case study to learn how the potential energy savings for YCUA could easily approach $1 million over a decade.
Enhancing process reliability and increasing capacity are common issues facing water municipalities. On the one hand, community demographics are constantly evolving and water municipalities need to accommodate the impact to capacity requirements. At the same time, older systems that support pumping operations are not getting any younger and as control systems age, for example, it can become more time consuming to maintain equipment and more difficult to find replacement parts after systems have been in place for many years.
Achieving consistent water pressure is a challenge for geographical areas that have grown faster than the development of infrastructures to accommodate water demand and for businesses such as fast food restaurants and strip malls.
To ensure real-time monitoring of pump motor status at its five lift pumping stations, Sheboygan Regional Wastewater Treatment Facility, Sheboygan, WI, replaced its bi-metallic overload relays with Eaton’s Motor Insight™ overload and monitoring relays.
A key driver of economic development is the availability of water and wastewater services. For the Town and Village of Champlain, NY, this is no exception. To capitalize on the region’s economic potential and make more land available for new businesses, the Town and Village of Champlain are working together on the Shared Water Project, a major water system upgrade that includes installing 44,000 feet of AMERICAN ductile iron pipe.
With a population of about 15,000, Steinbach is the third largest city in Manitoba and one of the fastest growing areas in Canada. The current system has been operating since 1993, an eternity in the world of technology. Because the wastewater department was already familiar with operating the existing Xylem/Flygt M&C SCADA system with Aquaview software and APP controllers, they decided to inquire what new technologies the company could offer. Read the full case study to learn more.
In 2012 when Superstorm Sandy hit the New Jersey coastline, it devastated Route 35, a critical flood evacuation route, just north of Island Beach State Park. With this critical coastal evacuation route severely compromised, the New Jersey Department of Transportation (NJDOT) took immediate steps to restore safe travel.
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.
In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.
The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.
An ambitious, globe-trotting program invites attendees to learn from the infrastructure accomplishments and challenges of the world’s premier riverfront cities. With water becoming an increasingly valuable resource and the world’s drinking and wastewater infrastructure in peril, what can these metropolises teach us?
The journey to “smart” has proven more challenging for wastewater networks than for potable water, but real-world impact is imminent. Learn what potential awaits the industry at monitoring’s latest frontier.
A smart-water expert details the impact of data and analytics on the water sector.
The LoRa Alliance is a non-profit association of members who are collaborating together to drive the adoption of a communication protocol that offers long range, long battery life and open architecture. For water utilities specifically, the LoRa wide area network (WAN) would allow devices from multiple manufacturers to be able to communicate with each other across long distances.
Is "smart water" living up to the hype? Can there be true impact without broad implementation? Even when technologies are in place, are utilities using smart water capabilities to their fullest extent? Water Online hosted Reese Tisdale, president of Bluefield Research, to answer these tough questions.
Big Data is often characterized by the large volume of data, the wide variety of data types and the velocity at which the data must be processed. Data can come from many different sources, such as social media use, online purchases, licensed twitter data streams or sensors used in the Internet of Things (IoT).
