Talk about making waves. Cryptocurrency — digital “tokens” or “coins” rooted in computer code and valued for the very fact that they are disconnected from governments and banks — have experienced spectacular rises and falls in recent months. The crypto-economy is already worth hundreds of billions of dollars (REAL dollars!), and it’s anyone’s guess how fast it will grow after that.
The Metropolitan Water Reclamation District of Greater Chicago (MWRD) — of which the Terrence J. O’Brien Water Reclamation Plant (WRP) is part of — has made a number of upgrades to its treatment process in recent years.
Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.
Today’s selling space moves at the speed of light, and as the B2B industry continues to accelerate…only the survival-of-the-fittest salespeople will thrive. It’s crucial that sellers learn how to adapt to new buyer behaviors so that they can navigate through the sales process and close more deals.
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?
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.
More than 7,000 islands of the Caribbean Archipelago are scattered over a million-square-mile area between North and South America. Some smaller islands are naturally dry, but some volcanic islands — like Grenada and St. Lucia — are well forested and provide significant water catchment to support spring water and surface water. But, as populations, agriculture, and industry grow, desalination is becoming more attractive as a water source throughout the entire region.
Filtration has been around for a long, long time, so it may be that most treatment plant operators feel pretty informed about its capabilities. But hearing from Brian Frewerd, Director of Application Engineering with Parkson Corporation and Water Talk guest, will likely prove enlightening. Frewerd provides background on sand filtration for tertiary treatment applications, followed by insight on notable technology improvements and performance milestones
Beyond Independence Day or Veterans Day, it's always a great time to thank our nation's veterans for their service and reflect on the sacrifices they and their families have made on our behalf. This year, it's also a great time to add a plea — and an opportunity — for further service in the defense of our country: to take the skills they learned in the military and apply them to the water industry.

The city of Buhl, Idaho, obtains all of its drinking water from groundwater sources through multiple wells. Prior to 2009, the city did not treat the groundwater but only added chlorine in the form of bulk 12.5% sodium hypochlorite to provide a disinfectant residual. A combination of factors including: changes in EPA and state DEQ regulatory requirements, growth of the residential population and growth of the industrial food processing customers forced the City to build a new water treatment plant to provide filtration to address the naturally occurring arsenic present in the groundwater.
Operational savings realized through high-tech leak detection techniques could pay for your utility’s advanced leak detection equipment.
There are various treatment processes that are used to remove iron and manganese from ground water for potable water supplies. Iron and manganese are typically found in groundwater in a dissolved state and the water may appear clear. While there are various less common treatment methods used (such as ion exchange), most treatment systems for iron and manganese oxidize the ferrous state (clear iron) to a ferric state so the solid particles can then be filtered out.
A fish flour and fish oil processing company produces 100 tons of flour a day from fish waste resulting from the broth concentration plant and from drying of flour, washing water, boiler blowdown and cooling towers. The company needed to treat its wastewater and to reduce its water supply costs.
Microorganisms can wreak havoc in industrial processes in a number of ways – from slime formation that causes paper breaks and excessive downtime in papermaking facilities, to costly recalls of spoiled final product.
