As a bulk emergency chlorine vapor scrubber system approached the end of its anticipated 20-year useful life, the city engaged Integrity Municipal Systems, LLC (IMS) inspected the equipment and proposed a system refurbishment plan that would ensure proper system performance and safe storage of the 30,000 gallons of corrosive caustic soda contained within it.
From Nevada to South Dakota and now Tennessee, cities across the U.S. are installing the AMERICAN Flow Control® ALPHA restrained joint, because it saves labor, time and money. Introduced almost a year ago, ALPHA is used on AMERICAN’s Series 2500 4- to 12-inch Resilient Wedge Gate Valves and American-Darling and Waterous fire hydrants.
Workers Surpass Several Water-Related Challenges At UNC-Wilmington
Pump Station #8 was outfitted with old equipment and operation and reliability had become problematic. It was time to turn over a new leaf and embrace new technology to solve the problem.
Winchester Municipal Utilities (WMU) faced challenges regarding two separate sections of town. The lines required maintenance due to old inoperable inline valves that needed to be replaced. The challenge - replacing these valves using a procedure that eliminated the shutdown of the water lines that service hundreds of homes and businesses.
Business process management (BPM) has proven extremely successful in managing both gradual and radical improvements in the industry and various business functions. While digitization brings incredible new opportunities, it also brings the distinctive challenge of correctly positioning and scoping BPM in organizations.
Buchanan County had a project which required repairs to a pumping station that boosts the pressure high enough to get water to a tank at the top of a mountain. The line pressure needed to accomplish this is 250 psi. After considering options, Buchanan County selected the Hydra-Stop Insta-Valve 250 Patriot. Read the full project profile to learn more.
The toughness of AMERICAN ductile iron pipe was put to the test on a recent project that changed a significant portion of the landscape in Cobb County, Georgia: SunTrust Park, the new home of Major League Baseball’s Atlanta Braves.
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.
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.
Estimates of what it will cost to address the destruction wreaked by Hurricane Harvey are projected to be somewhere in the range of $160 billion, with work that will be required in Texas accounting for most of that total. That’s more than the total cost of Hurricane Katrina and Superstorm Sandy combined. Texas is now officially the new "hot spot" for government contracting of almost every imaginable type.
A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.
As wastewater systems have access to more data than ever, questions remain about how to put it all to good use. A new tool uses analytics to predict the needs of sewer lines over a 20-year span, helping utilities make cost-effective choices and protect their infrastructure.
Nestled in the Sandy Hook Bay, the community of Port Monmouth, NJ, has experienced flooding, blizzards, and major storms that have swept through the area throughout the years.
Kansas City’s Smart Sewer program represents the nation’s first federal consent decree to include green infrastructure solutions in the reduction of wastewater overflows, as well as the city’s largest infrastructure investment to date. Projects that include the words “first” and “largest” do not come along without the strong leadership of a “Water Champion” such as Special Assistant City Manager Andy Shively, PE, who shares his experience and expertise in this Q&A.
Water utilities are tasked with ensuring a sustainable and safe supply in addition to achieving business and service excellence goals. These goals are typically based on criteria that measure operational performance, meeting bond covenants, and customer satisfaction.
