According to trade groups, approximately 45 million packs of medicines leave the U.K. for Europe every month, and 37 million go in the opposite direction. In a year, that’s almost 1 billion packs of medicines. What those borders would look like after a Brexit deal would significantly impact major industries in the U.K. and EU economies.
Potable reuse offers a massive opportunity to recover water from the wastewater process, but projects face a variety of barriers to getting off the ground. Most successful early adopters engaged early with their constituents and implemented smaller-scale demonstration projects that were accessible to the public to prove the technology and process.
In one of Pennsylvania’s three original counties, water has played an integral – even historic – role in the region’s development.
In a recent keynote speech at Wharton’s Initiative for Global Environmental Leadership (IGEL), Innovyze CEO Colby Manwaring took the stage to address the current state of flood modeling techniques. The story? We can do better.
Planning and preparation are the keys to success in any enterprise, and making plans for the possibility of equipment liquidation from the time of procurement is no exception. There are clear advantages to planning for your facility’s future, especially if it includes the opportunity for cost savings or a new way to look at purchasing budgets.
For decades, wastewater management has been a growing problem for the Wider Caribbean Region (WCR), a problem that regional governments have long understood as a threat to the economy, the environment, and to public health. In the Caribbean, most wastewater from cities, industry, and agriculture pours directly into surface water or into the sea completely untreated, degrading residents’ quality of life, as well as the region’s biodiversity, pristine blue waters, and reefs, which are the lifeblood of the vital tourism industry.
New technology helps utilities meet the challenges of maintaining a safe and adequate public water supply.
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.
Queen’s immortal Bohemian Rhapsody asks a question that can directly apply to mathematical models: How do we know that numerical models are true? How do we know that they are defensible? More importantly, how can a modeler convey to customers the care he or she put into the model itself? Those questions are important to the water industry, where leading companies are making better use of sophisticated models every day.
Ozone disinfection has long been a critical process in the wastewater treatment industry. And, because ozone is relied on so heavily to oxidize a wide variety of potential wastewater contaminants, water quality analysis during the disinfection process is paramount. Once the ozone process itself is understood, its water quality ramifications and the quality parameters that offer insight into its efficacy can be analyzed and taken into account.
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?
Iron, manganese, arsenic and hydrogen sulfide are indigenous to numerous groundwater aquifers. With the exception of arsenic, these constituents are more prevalent in deeper aquifers that are devoid of dissolved oxygen. This report summarizes the results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to determine the removal performance for arsenic, manganese and iron at the City of Merced’s Well 20 site. Chemical treatment processes required were also studied.
For those who appreciate the old maxim about catching more flies with honey, the logic of creating a more favorable biological environment for better biological nutrient removal (BNR) makes perfect sense. Worldwide implementations of flat-sheet membrane aerated biofilm reactor (MABR) technology are doing exactly that — in less space, with less energy, and with lower operating expenditure (OPEX) for aeration and chemical treatment. Here’s how:
The use of chlorine to treat and disinfect drinking water and wastewater has been in practice for decades, with the earliest recorded attempt dating all the way back to 1893. Since then, it has come a long way.
Understanding the different considerations for bioburden control in various operations and production steps can help define a strategy for successful production.
Sampling and laboratory testing are major responsibilities for water professionals. Test results are used for process control, and ultimately to determine that water is safe for drinking, reuse, or discharge to the environment. Regulatory agencies rely on reported results for proof of permit compliance. So, obtaining representative, properly collected and preserved samples is the first critical step to ensure accurate test results.
Beyond the existential philosophy implications, the consequences of a pipeline leaking in a forest when no one is around highlight the desirability of leak detection systems in water distribution utilities as a whole. As the following experiences show, leak detection can have its entertaining side. On the other side of the coin, however, the consequences of not monitoring leaks can also trigger a tsunami of costs far beyond the expense of pipeline repair alone.

The City of Baxter, located in central Minnesota, has always endeavored to deliver superior and reliable service to their customer base with a strong dose of selfreliance.
Precise water quality is critical for municipal water treatment operations, but many industrial applications have even more rigorous requirements, regulations, and guidelines to follow. The energy, pharmaceutical, food processing, and other industrial fields require exact water quality in order to function efficiently.
A helpful guide through all steps of a bioprocess, starting from the preparation of the inoculum to the preparation and operation of the vessels and bioprocess systems, the bioprocess run itself, and the analysis of samples.
In water plant operations, there’s no such thing as simply maintaining the status quo. Any utility that is not moving forward is falling behind. Whether a water treatment or wastewater treatment plant (WTP/WWTP) chooses to rely on in-house resources or outside specialists, here are some lifecycle management approaches they can use to upgrade control capabilities without compromising performance or return on investment.
Industrial companies need reliable water treatment technology, since failure of a water system may result in downtime for production, with significant financial impacts. Ultraviolet (UV) technology is used for water treatment in various industries such as microelectronics, food & beverage, pharmaceuticals, and many other industry segments.

The Cape Breton Regional Municipal (CBRM) Water Utility in Nova Scotia supplies potable water to a population of 81,000, which is distributed over 478 miles (770 km) of pipeline. To do this, they operate, maintain and manage 5 water treatment plants, 6 pumping stations, 11 water storage tanks, 8 sources of supply, 2,900 fire hydrants, 28,700 water meters and thousands of valves.
There’s a lot to be said for the old adage, “Use the right tool for the job.” When it comes to flow meters for municipal or industrial water treatment plant (WTP) and wastewater treatment plant (WWTP) operations, however, the sheer number of choices can be overwhelming. That is where using a process of elimination to winnow out styles that don’t fit the performance criteria of an application can make it easier to compare the few remaining options. Here is a checklist of considerations to accelerate that process.
Saturday, March 24th was a busy day at the Brightwater Clean-Water Treatment Facility in Woodinville, WA, just outside Seattle. The Utility’s Education and Community Center was full of family-oriented science experiments and art projects with organized tours of the wastewater treatment plant taking place throughout the day. All in recognition of International World Water Day which had occurred two days before.
Eastern Municipal Water District (EMWD) serves about 142,000 customers in Riverside County, CA. The EMWD service area is one of the largest for any water district in arid southern California. On the drinking water side, EMWD manages two water treatment plants and over 15 reservoirs. With 70% of the district’s water coming from the Metropolitan Water District with chloramine disinfection, EMWD has become reliant on chloramine disinfection to manage long transmission lines and longer detention times.
