ABB provides an extensive selection of proven measurement and analytical products and solutions for power generation industry applications.
When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.
Water is the lifeblood of electrical power plants, whether they are water-cooled steam plants or turbine-spinning hydroelectric installations. Regardless of how the facility generates electricity, there is a growing awareness that each power plant is part of its own, unique industrial watershed — drawing water from the environment, altering its contents and temperature, releasing some to the atmosphere as steam, and returning the rest to receiving waters.
Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown.
Water’s high heat capacity, high thermal conductivity, and historically low cost make it popular for process heat exchange. Power plants, especially those for liquid cooling applications, withdraw a large fraction of the total demand for water necessary for agriculture, industry, recreation, hygiene, drinking, and wildlife.

Veolia furnished West Deptford Energy with a BIOSTYR® Biological Aerated Filter (BAF) and Hydrotech Discfilter system, allowing effluent from a municipal wastewater plant to be reused, with a treatment capacity of 7.35 MGD, in the operation of their new “green” energy station.
When the polar bears at the Brookfield Zoo were introduced to their new habitats at the Great Bear Wilderness, they had no idea how much more fulfilling their life would become.
Dissolved gas control in a nuclear power plant’s water system, including the primary make-up water storage tank and refueling water storage tank, can be essential to reduce radiation source term (defined as a release of radioactive material). In particular, controlling dissolved gases can also help reduce the formation of unwanted radionuclides, such as 14C and oxides of 60Co, and alleviate primary water stress corrosion cracking (PWSCC).
Glendale Heights Wastewater Treatment Plant discharges treated water to the East Branch of the DuPage River in Illinois.
During an upgrade project to install combined cycle gas turbine (CCGT) technology, the process engineers at an electric power plant in Western Europe also wanted to maximize the efficiency of their existing gas fuel turbines while maintaining the highest safety levels. By optimizing the performance of both the existing gas fuel turbines and adding the new steam turbines, they hoped to add significantly more generating capacity.
See how Xylem partnered with WateReuse Colorado and Invintions Winery to create wine using purified recycled water.
At Fluence, we have more than 30 years of experience in the design, construction, and operation of waste-to-energy plants for a wide range of industrial and municipal clients. Our proprietary anaerobic treatment technologies process wastewater and sludge to produce biogas, which can be used to produce electricity and thermal energy, or which can be purified to produce biomethane for injection into the grid.
L'eau Claire upflow filters offer an alternative to conventional water clarifiers for removing suspended solids and colloidal material such as silica. Despite the influent loading, this cost-effective filtration process removes 98% of particulates ≥2 microns without the use of clarifiers, flocculation, sedimentation, dry chemical addition or mixers. Watch the video to see how it works.
A hospital had been pumping their wastewater with a submersible pump for years. But after seeing the benefits of the S&L Above Grade Wet Well Mounted Pump Station, they quickly saw the benefits - easier and safer maintenance, higher efficiency, long pump life, and more. Hear from the operator himself to learn why the hospital now prefers S&L's EVERLAST™ Wet Well Mounted Pump Station.
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.
Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match their needs.
Global demand for power and water is accelerating — and the Middle East is no exception. A burgeoning population combined with multiple industrial diversification programs is fueling a boom in power and water projects. During the first three quarters of 2017, about US$30 billion of major power contracts and US$20 billion of water projects were awarded across the region. In 2018, the figure is looking more like $60 billion with the two sectors combined.
In Cape Town, South Africa, the countdown is on for Day Zero when water taps in the city of 4 million people are expected to run dry.
There's a hidden threat to Indian energy companies' revenues — water.
Energy Secretary Rick Perry is trying to prop up coal and nuclear companies under the guise of enhanced “resiliency.” The Department of Energy’s (DOE) proposal does not define resiliency, nor does it even make clear what resiliency means in the context of the electric grid.
You can’t control what you don’t know and when it comes to gas mixtures, control is of vital importance. But how can you get a handle on all of the elements you’re processing at a given time?
Unbeknownst to many, coal ash is one of the most prolific industrial wastes affecting wastewater quality in the country, with more than 100 hundred million tons produced each year. And treating for the byproduct is paramount, with health concerns and stringent regulations in place governing its removal.
Utilities are faced with myriad threats looming in the future, but chief among them is increased stress from population growth. In Denver, comprehensive planning for that future is underway.
Amid growing concerns around algal bloom, industrial operations are under pressure to stop using phosphorus-based water treatment technology. But transition to an alternative can be daunting.
India is making great strides to aggressively expand its renewable energy capacity. But the country's power sector remains highly reliant on thermoelectric plants, with high demand for water for cooling. That means that droughts, like the one caused last year by weak monsoons, can shut off the power, hampering the economy and potentially endangering lives.
Resiliency is a hot button word right now. Ten years ago, advocates focused on “adaptation,” or the idea of adapting to the coming effects of climate change. Now the focus is on “resiliency,” the ability to bounce forward — not backward — when something disastrous happens.
We’re entering the home stretch of the 85th Session of the Texas Legislature.
It may sound intimidating, but water that has been treated to “ultrapure” condition is more than necessary in many applications. This highly-cleansed product is a fundamental part of many industrial operations, from the medicine we need to get well to the power we rely on in our daily lives. But, as the name implies, it’s no small task to get average influent to the ultrapure level.
