Megalim Solar Power Ltd’s Power Station, located in Israel’s northern Negev desert, will be the first utility-scale solar thermal or concentrated solar power (CSP) plant in operation in Israel when completed. To minimize fresh water usage in the cooling cycle and boiler makeup of the power plant, Fluence designed and supplied a containerized system for treatment of cooling tower blowdown wastewater for reuse and the production of ultrapure water (UPW).
Toxic algae is creating headaches for Milwaukee officials this summer.
Following a lengthy legal battle, Escondido City is almost ready to begin construction on a new $33 million recycled water treatment plant.
To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.
A contractor for San Jose Water Company in San Jose, California, has taken delivery of more than 3,000 feet of zinc-coated iron pipe from AMERICAN Ductile Iron Pipe, making it among the nation’s first utilities to install zinc-coated pipe.
In a nation of red states and blue states, water policy is an issue that often dissolves party lines.
The City of Bloomington’s water purification plant has been operating since 1929. The lime-treated water has high pH which can cause scaling and can eventually clog the piping and filters in the plant. So, the plant needs to re-carbonate the water thereby lowering and stabilizing the pH. CO2 is an effective and safe chemical that offers treatment flexibility for a utility doing pH control.
Utilities are under constant pressure to reduce costs, meet regulatory requirements, and improve sustainability. Finding the best way to meet these goals is a constant challenge. Endress+Hauser has been helping water and wastewater utilities achieve their objectives for many years, and spoke with Water Online to discuss how to save
energy in today’s wastewater treatment facilities.
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
Summer reading list a bit dry? Drink up these books on the world’s greatest resources — water.
For decades, a Winnipeg utility used a multiple point-chlorination process to treat raw water drawn from remote Shoal Lake. Concerns eventually arose about the potential presence of chlorine-resistant pathogens–Crytosporidium and Giardia–and residual disinfection byproducts, which coincided with encroaching development near the lake. The Clari-DAF system was selected and now removes 70 percent of the organics at the Winnipeg plant, which also improves filtration and extends the intervals between filter backwashes.
In August 2014, the city of Toledo, Ohio informed its residents (~500,000 people) that they should not use tap water for any purposes including bathing and cooking. The culprit: microcystin, a toxin produced by blue-green algae, had been detected in the city’s finished drinking water at concentrations 2.5 times the World Health Organization’s guideline value.
This article is in support of the Imagine a Day Without Water campaign –- a national online movement to raise awareness about the value of water and water infrastructure. See more articles on AMERICAN’s Imagine a Day Without Water home page.
As sweater weather approaches, it’s a good time to revisit a USGS report from last year highlighting the importance of leaf removal for keeping phosphorus and nitrogen out of urban stormwater.
Research from the UK has identified a “supermolecule” capable of seeking out and eliminating trace pharmaceuticals that contaminate water supplies.
A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.
Since its introduction in 2015, the Clean Water Rule and its Waters of the U.S. (WOTUS) clarification have simultaneously drawn condemnation and praise. As Trump’s administration is now poised to replace it, it’s important for treatment operations to consider where they stand.
Wastewater treatment in India can no longer be seen as some conservational fad. With depleting freshwater sources, water treatment is absolutely imperative. Depleting water resources is a worldwide problem with almost all nations grappling with water scarcity. But India’s massive population, coinciding with rising pollution, makes its water scarcity and clarity concerns critical.
High levels of radionuclides (uranium/radium/etc.) in drinking water aren’t very common, but they are very dangerous. If you’ve long dealt with radionuclides, you’re familiar with the treatment requirements — but are you treating as cost effectively as possible?
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
At the end of The Big Short, a postscript stated that one of the story's protagonists, Dr. Michael Burry (played by Christian Bale), was now focused on investing in only one commodity: water. That got my attention.
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.
Since chlorine technology was first used to disinfect drinking water in Jersey City, NJ, in 1908, most waterborne diseases have been eliminated in the U.S. Chlorine is still the most common disinfectant for drinking water and wastewater. Chlorine is also used for disinfection and as a biocide in numerous industries.
For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.
There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.
