This article shares new strategies for enrolling patients and outlines the challenge of measuring the efficacy of the experimental treatment and determining whether it’s producing the desired effect.
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.
Utilities looking for greater billing efficiency and control over every drop of water consumed by their customers face a constant battle with non-revenue water loss, which can be compounded by different metering technologies and consumer behaviors. Using accurate, always-on, continuous-sampling meters to take full advantage of automated smart utility networks is a better way to improve decision-making and achieve accountability goals across any circumstances.
It’s the call no water treatment plant superintendent wants to receive, especially not while on vacation. Andy McClure, Superintendent of Toledo, Ohio’s Collins Park Water Treatment Plant, answered his phone to hear his head of operations report that the level of microcystin in the finished water was high, caused by a large harmful algal bloom (HAB) that was impacting the plant’s Lake Erie intake.

Water utilities are installing automated meter reading (AMR) and advanced metering infrastructure (AMI) systems more frequently. These systems often help utilities improve customer relations and provide valuable real-time data to improve operations. The ability for various meters to communicate with AMR and AMI technology has become more important as these systems become commonplace.
The federal government recently released its fourth National Climate Assessment which focuses on the impact climate change will have on the U.S. economy over the next century. As mandated by the Global Change Research Act of 1990, the U.S. Global Change Research Program takes a comprehensive look at climate change and its effects on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems and biological diversity.
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?
In recent years, hollow fiber membrane degassing modules have become an ideal option for CO2 removal when compared to harmful, costly chemicals and bulky deaerating towers.
In the Semiconductor industry, raw water is treated in two steps; the first treatment is used to produce “make-up water” and the second phase involves turning make-up water into ultrapure water. This ultrapure water is then used for the final rinsing of fabricated wafers.
Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused. Clean water is an essential part of daily life, from catchment all the way through to wastewater treatment, therefore analysis throughout the whole cycle is crucial. Whether in lakes, pipes, or bottles, we can accompany you with our range of instruments, test kits and applications for your water and wastewater needs.
In the wastewater treatment industry, coagulation has become one of the most widespread processes for effectively separating contaminants and effluent. But coagulation is a complicated and sensitive process, one that alters the chemical balance of the wastewater in order to strip it of unwanted constituents. As in many such processes, pH plays a critical role, and treatment professionals must analyze it closely if they want to properly coagulate their product.
The purpose of source water monitoring is to enable drinking water treatment facilities to identify changes in water quality, implement treatment strategies based on the characteristics of the water, optimize the treatment processes, and take preventative actions to protect the source water from intentional and accidental contamination.
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.
With the proliferation of sensors, data collection, and cloud storage, there is the potential for operational insight heretofore never available, and the opportunity will only expand as the technology evolves and the Internet of Things becomes, well, more of a thing. But data is only truly useful if it informs decision-making that results in positive impact — for an organization's bottom line, its personnel, its customers, or even the world at large (i.e., the environment).
Fine-tuning for best performance at water treatment plants (WTPs) and wastewater treatment plants (WWTPs) requires versatile and accurate instrumentation to monitor and respond to changing conditions. Getting the most out of those meters, gauges, and analyzers requires knowledgeable operators. That is why instrumentation decisions should be made not only on feature-rich technologies and quality performance, but also on the documented support and training that will enable staff to maximize the value of the investment.
For some water providers, carefree days of producing pure, fresh water from groundwater sources are long gone. Years of evolving chemical complexity, industrial operations, and short-sighted disposal methods have taken a toll on groundwater sources. The lowering of maximum contaminant levels (MCL) for contaminants such as chromium and the drilling of new wells into different geologic structures add to source water pressures. Fortunately, new technologies are helping water providers make the best of a challenging situation across a wide range of contaminants.
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.
