For a community to have a clean and dependable water supply, it must build and maintain high-quality drinking water and wastewater infrastructure. While some modernization has been achieved, there is still much work to be accomplished.
There has been no shortage of studies, discussions and debates surrounding the concept of energy efficiency over the past 40 years. Scientific studies suggest a relationship between greenhouse gas emissions and global climate change, strengthening the belief that human activity was harming the environment.
Following a controversy that dates back over one hundred years, Jersey City’s water and sewer system operator will soon have to pay millions for outsourcing its wastewater treatment operations.
Water plays a critical role in our communities and in our future. As infrastructure systems age and population growth continues to flourish across the U.S., communities must be equipped with long-term, sustainable, and up-to-date water solutions.
In a sign of just how problematic aging water infrastructure still is for major cities around the country, a National Resources Defense Council (NRDC) spokesperson described lead levels in Newark’s drinking water as “jaw-dropping” and “knock-your-socks-off high.”
Water and wastewater professionals rely on accurate flow measurements for process operation and regulatory compliance. Selecting the best flow meter for each application is essential to obtaining accurate flow data.
Propeller flow meters have long been an important tool for agricultural irrigation management. As water scarcity and resource management have become increasingly critical, getting the most timely, accurate readings available from those meters is becoming more important than ever. Here is how growers and water conservation districts (WCDs) are each getting the best of both worlds for their own purposes.
Following federal charges that he manipulated water sample test results to mask plant discharges, the ex-supervisor of a wastewater treatment plant in Sioux City, IA, plans to plead guilty.
Our planet continues to become increasingly more crowded. Pollution and waste are showing irreversible impact on a global scale, and it has become necessary to come up with solutions in all industries. It is widely known, though perhaps not publicly thought of, that the process of purifying water creates waste. As we remove the minerals and impurities from water, we inherently condense those impurities into a smaller body of water. This waste affects the environment in various adverse ways. The solution lies in a concept known as Zero Liquid Discharge (ZLD).
Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.
The advanced oxidation process removes contaminants in water and wastewater by oxidation through reactions with highly reactive hydroxyl radicals (.OH). This chemical process uses ozone (O3), hydrogen peroxide (H2O2), and/or UV light.
Rosy-cheeked children and romantic-eyed couples bundled up and laughing as they enjoy a skate around the frozen pond. It’s an iconic and idyllic vision every winter. But this fairytale-like scene “frosts over” significant issues faced by water companies and conservationists, not to mention homeowners and other types of service providers.
Entering its fourth week and now the longest in the country’s history, the partial government shutdown is affecting a wide range of federal employees and agencies. Naturally, water and wastewater treatment operations are no exception.
Advanced analytics and data collection system help an energy company monitor and evaluate gas processing equipment at remote well sites. Unmanned well sites in remote locations present operational challenges. Data must not only be collected, but it also must be monitored to uncover any discrepancies, and ideally to predict problems before they occur. Advanced analytics software, coupled with a sophisticated data collection system, can address these issues, and also provide additional benefits.
The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.
In the past several years, Aquarion Water Company had been monitoring their system’s THM formation and attempting to lower them through treatment and distribution system changes. Aquarion engineers decided that reducing THM formation in the Laurel High Service Clearwell at the Stamford Water Treatment Plant (WTP) would eliminate concerns of elevated THM formation in the distribution system served by the WTP.
Keeping an eye on what happens with domestic oil and gas regulation is a bit like herding cats. We’ve seen encouraging progress on air quality issues related to oil and gas, but an equally critical front that’s seen major action is protection of our land and water resources.
The development of Industrial Control Systems (ICS) over the past two decades has changed the face of many industries. Operation Technology (OT) — largely industrial equipment — has become increasingly connected, and the integration of Information Technology (IT) components allows such devices to leverage software that drives data collection and analysis, resulting in enhanced performance and ultimately "smarter" machines.
Few regions around the country have as much at stake during prolonged droughts than Arizona. After months of negotiating, the state now has an approved framework for a drought contingency plan (DCP), though it faces some obstacles.
A global beverage company produces, markets, sells and distributes a variety of beverages including beer, malt, soft drinks, fruit juices and mineral water. The brewery has utilized several types of SITRANS F flowmeters from Siemens to regulate all aspects of the brewing process for more than a decade, including SITRANS F C Coriolis meters to monitor the sugar concentration in wort prior to fermentation.
Drilling fluid is critical for successful oil extraction. Typically made up of water, clay and a complex mix of chemicals, it supports the drilling process in a variety of ways — from lubricating and cooling the drill bit under high-temperature and high-pressure conditions, to lifting drill cuttings to the surface, to maintaining oil well stability and safety. But drilling fluid is not a “one size fits all” solution. To work properly, the fluid must be optimized for the unique geographic conditions of individual well sites.
With time, labor, and money at a premium, state-of-the-art controls on filtration equipment can ease the burden on operators while improving uptime and lowering costs.
Advanced oxidation provides an all-in-one solution that supports the complete eradication of Legionella in a water system, while also preventing its regrowth.
A labor crisis has been bearing down on the water industry for some time, so it’s time to prepare for the future. Luckily, some industry trailblazers have charted paths to success.

Rio de Janeiro boasts the world's largest water treatment plant, and it's working overtime. The Guandu Water Treatment Station provides 90 percent of the city of Rio's water, and it's increasingly grappling with water quality problems. One challenge is that forest loss and landscape degradation upstream of the city is causing soil erosion, which generates more pollution, and fills reservoirs with sediment instead of water.
A carpet manufacturer in Belgium produces 23,920 sq. yds of tufted carpet every day. To increase the flexibility of its machines and reduce costs, the company decided to stop manufacturing its dyes in batches and switch to a continuous process using an inline mixer that produces the right color instantly. Read more to learn how this was accomplished with the help of the SITRANS FC410 mass flow meter.
In a sign of just how significant water quality concerns are in Michigan, the state’s governor elect signed an executive directive related to the issue as her first such move in office.
The oil and gas industry, like many others, is collecting and storing ever larger volumes of data. Although, there is value in this data, it is often difficult to unearth using conventional analysis tolls such as spreadsheets. To address this issue, new data analytics software platforms are being introduced specifically to deal with time-series data.
