Drinking water and wastewater systems are generally the largest energy consumers for municipal governments. However, there is little published information available on the exact energy usage for specific systems.
Water utilities must protect the public health by producing a final product that meets all regulatory requirements. In addition, the water must be pleasing to the customer, with no taste or odor issues. And finally, utilities must stay abreast of emerging contaminants, health advisories, and new regulations. It’s a constant challenge to shoulder these responsibilities while staying within tight budgets. Utilities need a technology that helps them achieve multiple goals cost-effectively.
Wastewater treatment plants process tons and tons of sludge every year and they have to contend with the question of what to do with it. Increasingly, biosolids are looked at as an opportunity to help the planet.
Nick Burns, director of water treatment technology for (the Americas region of) Black & Veatch, discusses the health concerns, current regulatory status, and documented presence of perfluorinated compounds (PFCs), also sometimes called perfluoroalkyl substances (PFAS), in drinking water supplies — as determined by sampling under the U.S. EPA's Unregulated Contaminant Monitoring Rule 3 (UCMR3).
By now, just about everyone in the U.S. has heard about Flint, Michigan’s water woes. Despite the many issues raised by that incident, urban water systems are not the sole reason the 2017 Report Card from the American Society of Civil Engineers gives the U.S. drinking water infrastructure an overall “D” grade. Hidden within that disheartening rating are the harsh realities faced by rural water systems.
It’s no secret that the U.S. EPA has changed course in the last year. But how have those changes affected local water and wastewater treatment operations? And how are those operations going to evolve along with the federal agency?
PFC contamination is the number one drinking water issue today. So how are local and federal leaders working to put an end to it?
Last year was full of twists and turns for the drinking water and wastewater treatment industries. What can 2017’s biggest stories tell us about what’s to come this year?
As with so many other drinking water treatment processes, corrosion control demands a delicate balance among multiple factors. From the water-purifying chlorine that increases corrosion risk, to alternative strategies that reduce corrosion — using either elevated pH or phosphates — keeping corrosion under control requires sound strategy and reliable execution. Here are several approaches to addressing those conditions, along with options for better, more effective corrosion control.
This articles provides some fundamental tips and tricks to preparative chromatography that will yield a pure sample preparation that will advance protein characterization studies.
Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
Is the hype surrounding biosimilars real or simply a hopeful view on an exceedingly expensive drug market? Substantial savings with these effective alternative treatments have been promised, but can they really deliver a viable alternative treatment?
Understand the analytical challenges faced when implementing the BPOG protocol for four SUS components.
Since chlorine technology was first used to disinfect drinking water in Jersey City, NJ, in 1908, most waterborne diseases have been eliminated in the U.S. Chlorine is still the most common disinfectant for drinking water and wastewater. Chlorine is also used for disinfection and as a biocide in numerous industries.
Most of us use computers or smartphones on a daily basis. But we usually don’t know what goes on behind the scenes — the technology that allows us to use cloud computing or even Google search. And we certainly aren’t aware of the infrastructure needed to support that technology — like cooling towers.
When California capped chromium-6 in drinking water at 10 ppb in 2014, it became the only state to set a chromium MCL and, in so doing, created a challenge for water providers across the state. WRT (Water Remediation Technology LLC) has met that challenge with the SMR™ (Selective Metals Reduction) Process.
Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort.
New technology helps utilities meet the challenges of maintaining a safe and adequate public water supply.
Total nitrogen (TN) has become a compound of concern because of its impact on eutrophication on water sources. And as more states begin to set limits for TN, accurate testing becomes paramount. Unfortunately, multiple labs and variable test procedures can lead to disparities in final results. Many of today’s test methods are also time consuming, expensive, and even unsafe for lab technicians to use.
Utilities continually face new challenges. Where treatment facilities were once expected to simply disinfect the water, they must now avoid creating disinfection byproducts during the process. New and more stringent regulations require removal of additional micropollutants and emerging contaminants. Finding the best technology to accomplish these goals can be difficult.
The quality of drinking water is regulated by a variety of guidelines, such as the EU Council Directive 98/831,2 and WHO guideline. The key principles used to define these limits consider both health hazards and sensory and technical reasons. Iron, for example, does not exhibit a risk for health in concentrations usually found in drinking water.
