According to the Army Corps of Engineers’ website, a project study in the mid-1980s pointed out, and further studies have since shown, the region’s groundwater resources are rapidly shrinking.
Andy McClure and Jim Knepper of Jacobi Carbon recently sat down with Water Online Radio to discuss the differences between activated carbon and ion exchange resins as mediums for water purification. The interview covered recent developments such as the lowering of the EPA’s health advisory level for perflourinated compounds and cyanotoxins from algal blooms to the more traditional concerns of taste, odor, disinfection byproducts and TOC reduction.
Not all water treatment needs are the same. That’s why it’s imperative to work with those that understand the subtle differences that make each industry unique. For food and beverage companies, that means aligning with KLa Systems, a company focused on oxygen transfer with a track record of innovation in jet aeration and mixing.
With increasing pressure on water resources, efficient and reliable wastewater treatment systems are crucial. Plants are searching for solutions that offer a smaller footprint and higher quality effluent. Over the last 15 years, membrane bioreactors (MBRs) have become increasingly common in both municipal and industrial wastewater treatment plants and help mitigate against effluent suspended solid issues. These systems combine a membrane filter with an activated sludge process where microorganisms are able to thrive and break down contaminants.

Ultraviolet (UV) irradiation is used for multifunctional purposes. UV is most commonly used as an environmentally friendly alternative to chemical disinfection. It’s one of the most effective methods for inactivating harmful pathogens such as Listeria, E.coli, Giardia and chlorine tolerant pathogens like Cryptosporidium. UV is also used for removal of organic and inorganic contaminants, including chlorine, ozone and Total Organic Carbon (TOC). UV used in conjunction with an Advanced Oxidation Process (AOP) will remove Compounds of Emerging Concerns (CEC's), Synthetic Organics (SO's), Endocrine Disruptor Compounds (EDC's) and Personal and Pharmaceutical Care Products (PPCP's), as well as various taste and odor compounds from water.
In the adsorption process, contaminants break their bond with the water molecules and chemically adhere to a filter media. This is typically accomplished by directing the water flow through pressure vessels containing the filter media at a rate that allows enough contact time for adsorption to occur. AdEdge Water Technologies’ Bayoxide E33 adsorption media is the industry standard for arsenic removal. This granular ferric oxide media reduces up to 99% total arsenic, including both Arsenic (III) and Arsenic (V).

“Water Champion” Paula Kehoe looks to do for the nation what she did for San Francisco — to greatly expand water reuse opportunities and implementation. In this Q&A, she discusses her new role as chair of a national commission for onsite non-potable reuse, the San Francisco model, and the best practices and obstacles for sustainable water operations.
The Water Environment & Reuse Foundation introduces a “bundle of research” to help direct potable reuse and its practitioners reach full potential.
When I speak to communities about water quality issues, people often think the problem only happens in the developing world. Although America’s drinking water remains among the safest in the world, we are facing a serious and growing problem at home in the U.S.
To minimize losses and address mounting concerns, the water industry is now adopting advanced sensor and communications solutions designed specifically for “smart” Internet of Things (IoT) water management. In large part, the move toward implementing smart water solutions is being driven by stricter government compliance requirements, the evolution of smart cities, and the need for water conservation.
In the Himalayan mountains, irrigation can be a challenge. There are few affordable pumping technologies accessible for poor farmers, and they come with high maintenance costs.
When snow arrives in the mountains, winter sports enthusiasts get excited. And, farmers “down country” get excited, too, but not for all the same reasons.
There’s roughly 32 billion gallons of municipal wastewater produced every day in the U.S., but according to a 2012 water reuse report by the U.S. EPA, less than 10 percent of that water is recycled.

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.
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.
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.
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.
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?
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.
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.
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.
