The sky is blue, grass is green, and, someday, your pumps are going to clog. It’s just another fact of life — or is it?
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).
As utilities update their metering to automatic meter reading (AMR) or advanced metering infrastructure (AMI) systems, integration with measurement devices in the distribution system has many benefits. McCrometer’s Dan Hardin recently sat down with Water Online Radio to discuss the flow measurement company’s Smart Output protocol that allows mag meters to connect to a water district’s AMI/AMR system.
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.
The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure.
In the upcoming U.S. presidential election, China has emerged again and again as both threat and ally. With all the talk about trade, economic balance, and military concerns surrounding China, this is a timely opportunity to dive into a little-discussed aspect of Chinese global power plays: water.
No water contamination issue is grabbing more headlines these days than that of perfluorinated chemicals, commonly referred to as PFCs or PFAS. Concerns over the chemicals have sprung up all over the country, prompted by contamination from industrial wastewater and military firefighting foam. Regardless of where the issue has come up or what caused it, everyone who has been affected wants the same thing: an effective treatment solution. To discuss such a solution, Water Online spoke with Calgon Carbon Corporation.
Rapid industrialization and tightened water quality standards are leading to an increase in global spending on water quality monitoring instrumentation. Spending in this area is projected to grow from $2.5 billion in 2014 to $3.6 billion by 2020, with some 25 percent spent on new, less expensive water quality monitoring sensors that deliver on-the-spot measurements.
A popular weed killer appears to be threatening consumer health through drinking water supplies. As knowledge around this threat grows, treatment operations should consider their technology options.
When it comes to the history and DNA of a city, new buildings have nothing on century-old ones. Yet the reverse can be said in regard to water and energy efficiency. Older buildings reflect the culture and history of a community, but typically are highly inefficient.
San Francisco’s water and wastewater utility has developed a holistic approach to resource management, sustainable infrastructure, and reuse. What can other utilities learn from its program?
A water recycling project in Colorado combines natural processes and cutting-edge technology to ensure drought security for its residents.
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.
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.
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.
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?
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.
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.
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.
