A new study out of Yale University adds fodder to the argument waged by the energy industry that fracking is not a threat to drinking water resources.
The successful addition of new restaurants and clubs at a resort and casino in Upstate NY brought with them a flow of fats, oil and grease (FOG), which gelled into a floating blanket atop the main station’s wet well, where the sewage flows converge from the network of smaller stations throughout the property boundaries.
This is a story about three cities in North Carolina: Albemarle, Concord and Kannapolis. Albemarle, 40 miles east of Charlotte, had excess capacity in its water system and needed new customers to defray costs.
Submersible sewage pump type ABS XFP CB Plus is designed for municipal and industrial wastewater equipped with premium efficiency IE3-level motor. Suitable for clean water and wastewater, sewage with sludge and high contain of rags, solids and fibrous material.
Accurate flow measurement is often overlooked at a water treatment plant. Many operators look at flow as being what it is. In reality, accurately measuring your plant’s flow(s) is critically important for operational efficiency, from back-washing to chemical dosing and a host of other processes.
This video gives a brief tour of Swan's products and applications expertise, and also explains why Swan is named Swan.
Containerized water treatment solutions eliminate many challenges associated with developing a large-scale wastewater or desalination facility.
In this exclusive Water Online video from WEFTEC 2014, Brian LaBelle of GF Piping Systems discusses the breadth of the Company’s product portfolio from pipe, fittings and joining technology to manual and actuated valves, sensors and instrumentation.
Xylem TotalCare Condition Audit, an inspection and recommendation program that helps plant operators find ways to lower maintenance costs by identifying inefficiencies in the operation of water and wastewater equipment, was elected to audit the American Canyon Wastewater Treatment Plant (WWTP) in California.
Smart Water Network (SWAN) is the water utility industry’s equivalent to the energy industry’s Smart Grid.
That’s a question that Jim Georger, regional sales manager with Kruger, a division of Veolia, discussed with Water Online Radio recently.
For nearly a decade, public utilities that draw from surface waters have been contending with a developing regulation that is emblematic of the U.S. EPA and the systems under its charge.
The federal regulation for arsenic has been in place since 2002, and yet many utilities remain noncompliant. The culprit isn’t treatment capability, but cost. It happens that the most popular treatment technique is also quite expensive — but it doesn’t have to be.
The U.S. Department of Energy (DOE) has proposed its first-ever energy standards for commercial and industrial pumps, aimed at saving energy in the agricultural and municipal clean water sectors.
Like so many schoolchildren sweating out final grades, the U.S. EPA gets its own report card each year, served by the EPA Office of Inspector General (OIG). Unfortunately, it’s full of bad marks.
Perchlorate is a chemical most commonly used in rocket fuel, flares, and fireworks, but potential federal regulation of its presence in drinking water may bring utilities down to earth.
Disinfection can rightly be called the “ultimate” stage of drinking water treatment — typically occurring at the end of the process, and acting as a final step before water is sent out of the plant, through the pipes, and into the world. It may come last, but it’s certainly not least.
The public works director responsible for a southwestern U.S. city’s drinking water supply reports multiple benefits from replacement of a problematic peristaltic pump system with a special liquid vacuum feeder system for bleach, liquid ammonium sulfate (LAS), and polyphosphate feeds at one of its well sites.
Faced with aging meters of all kinds from multiple manufacturers, the Etowah Water & Sewer Authority, about an hour north of Atlanta, looked to implement a complete replacement program, one that would not simply replace all existing meters but would also favorably position the Authority for years to come. Specifically, they looked for an advanced metering infrastructure (AMI) solution from one vendor that offered improved accuracy, greater longevity and forward-looking capabilities that would allow them to grow and develop as the future warranted.
Many waterways contain environmental contaminants resulting from agricultural runoff or industrial/municipal wastewater discharge. Possible environmental contaminants include nitrosamines, pesticides, pharmaceuticals, personal care products or other environmental contaminants. To protect residents from these contaminants, the City of Aurora set stringent water treatment goals, and adopted an advanced treatment process at the Aurora Reservoir Water Purification Facility. Find out what role our TrojanUVPhox™ plays in that process.
The City of Chester, IL was getting only about 6 months life out of the mechanical seals in their former non-clog lift station pumps. While replacing seals twice per year was difficult and expensive, the more serious problem occurred when the seals failed with the Mississippi River at flood stage and with the sealed lift station underwater.
Primex Controls is a full-service, system-integration company that builds everything from small, pump control panels to full-blown SCADA systems for water plants that serve 50-60 million people. In this Water Online Radio interview, John Buesgens, Business Development Manager with Primex, and Blair Sooley, Account Manager with Trihedral, talk about the value of the vendor integrator relationship for utilities.
Any operator will tell you that a treatment plant is only as good as its equipment. That means employing the devices with the longest lifespans, the lowest operating costs, and the most intuitive designs is critical.
In August of 2007, the Michigan Department of Environmental Quality issued seasonal ammonia discharge limits for the Coldwater Wastewater Treatment Plant (WWTP), which included a daily maximum ammonia concentration of 2.0 mg/L between the months of May and November.
Almost every industrial setting poses some potential safety risk to personnel working in such environments whether it is something that can be seen such as rotating machinery or unseen, such as possible lethal concentrations of flammable/combustible gas.
Out of sight, the country’s underground water infrastructure is aging and failing. In this interview, AMERICAN’s Derek Scott and Maury Gaston discuss the problem, challenges facing cities, and the latest technologies for providing and protecting one of our most precious resources — water.
By incorporating Membrana UF and Gas Transfer Membrane (GTM) a resort customer was able to reduce the risk of contaminating its cooling water and protect other system components from corrosion. The compact systems exceeded performance expectations and reduced maintenance and operating costs while maximizing the available space.
During the cold winter, the Quebec region enters a deep freeze, with temperatures often reaching -25 degrees Celsius.
Several years ago, Mueller began a journey to develop a user friendly and cost-effective technology to continuously and remotely monitor pressure at any point within a potable water distribution system. The technology involves threading a sensor onto a corporation valve to transmit pressure readings. The pressure sensor, typically installed two (2) per District Metering Area (DMA), reports at user-defined intervals via cellular service and a Mueller-hosted secure web server. Beginning with pressure monitoring, Mueller has created a communications backbone that utilities can integrate into its monitoring systems or use as a stand-alone monitoring platform. This technology is currently available in North America.
The TETRA LP Block dual parallel lateral underdrain system delivers distribution of air and water during backwashing to enhance filter cleaning and extend run times. TETRA LP Blocks were developed to overcome problems with air/water distribution experienced with other systems.
