Helping to maintain clean water is part of the Whalen family history, a story that begins in the mid-1990s with a father’s fervent belief that his research could make a difference and his son’s intense desire to ensure it did.
Hach’s off‐the‐shelf Real-Time Control System for Sludge Thickening (RTC‐ST) adjusts the sludge thickening process in real time. Thanks to the RTC-ST, a wastewater treatment plant improved thickened sludge consistency and gas production while reducing money spent on excessive polymer dosing and maintenance.
The replacement feeders also cut bisulfite consumption by 30 percent and ended the troublesome maintenance burden for instrumentation tech and plant operators.
Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.

A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.
Neptune Benson provides a wide range of filters and UV products for disinfection in both water and wastewater.
Those in the water industry know water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.
Here in the post-Flint era of municipal water operations, and for the foreseeable future, the loudest mandate for utilities will be to "get the lead out" of our distribution systems. Until such time that all lead lines are replaced, control strategies will need to be employed.
In the midst of this U.S. presidential race, a thought about Ronald Reagan (apolitical, I promise): Known as the “Great Communicator,” it’s certainly no coincidence that Reagan was an actor before becoming president; and honed communication skills, especially in times of trouble, are vital to effective leadership.
While it took a series of egregious bungles on several different levels to plunge Flint into the crisis, perhaps the most unforgivable lapse has been government officials’ negligent water testing.
This one's not on you, plant operators. Rather than a charge for utilities to aim higher in performance, the latest regulation to impact water treatment operations, as well as others, falls on equipment manufacturers — those who make pumps.
Name a contaminant, any contaminant, and chances are that the U.S. EPA’s new reference tool has you covered — or at least soon will. The recently revamped Drinking Water Treatability Database is set to include more than 200 contaminants, with detailed information on what they are, where they come from, and how to get rid of them.
If your plant is using anaerobic digestion to create biogas as an energy source, you may want to consider the blower being used to move the biogas from the digester to its point of use.
The Township of Shenandoah, Virginia was forced to comply with new regulations being enforced by the United States EPA concerning the removal of Cryptosporidium and Giardia Cysts from surface waters. Previously, no filtration was required.
Since 1969, Aqua-Aerobic Systems, Inc. has been a leader in the design, application and manufacture of wastewater treatment equipment and systems for municipal and industrial markets, worldwide. They are most noted for the Aqua SBR, the sequencing batch reactor, biological process, as well as now our cloth media filters.
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.
Municipal and Industrial water and wastewater treatment systems present a challenging environment in which the accurate and reliable measurement of liquid flow is essential for cost-effective plant operation.
Complete systems for the automatic and constant measurement and control of elevated chlorine concentrations.
In wastewater collection systems, raw sewage flows through gravity sewers to lift stations, which transfer the waste from lower elevation to higher elevations and eventually to a treatment plant. By Endress+Hauser, Inc.
Columbus Water Works (CWW) provides drinking water and wastewater services to more than 250,000 residents in the Columbus, GA, area. In 2004, Fort Benning and Columbus Water Works signed an agreement that said CWW would provide water and wastewater services for the military base for 50 years, requiring a connection of the two systems and several large upgrades.

The removal of nitrate via biological processes is well documented within the mining industry with numerous installations throughout the world.
When machine builders partner with subsystem specialists to simplify and streamline their equipment design, engineering, production, and support, they can save large amounts of time and, in many cases, up to 50 percent of costs — helping to boost profitability and customer satisfaction.
Precisely measuring and controlling the mixture of wastewater effluent, flocculants, and sludge is essential to efficient water treatment. The level/interface instruments that support the process liquid measurements must be capable of distinguishing between liquids with varying properties in order to detect the levels where the different liquids interface in the pond or tank.
McCrometer flow meters are in service worldwide — and even in outer space. From the American farmer to U.S. metropolitan water systems to subsea production systems in the North Sea to rugged industrial plants in Brazil, the Middle East and Asia, McCrometer meters are hard at work setting industry standards for the past 60 years.
Accurate partially-filled pipe measurement is essential when dealing with variable stormwater flows or over-sized community systems built for future growth. In Europe, new stormwater regulations requiring treatment before release are driving a change in measurement that will likely be seen in the U.S. in the not-too-distant future.
