Operating a wastewater facility is no easy task in today’s world. There are many challenges that owners / operators face, including sewage composition, water consumption, and an aging infrastructure.
Those in the water industry know water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.
The real MVP in professional football? Water.
Located in Northern Missouri, the city of Trenton and its more than 6,000 residents pride themselves on self‐sufficiency and pragmatic decision making. During the spring of 2012, the utility embarked on the design and construction of chemical feed system upgrades at the existing water plant that would help the city manage the need for new capacity, better control of trihalomethanes (THM’s) and improve operator safety by removing gaseous chlorine as a disinfectant.
If wastewater treatment plant operators have nightmares, it’s a good bet that many of them have to do with sewage overflows. Few events are as catastrophic for a wastewater facility as a surge of water it can’t process being churned out into the public sphere, in violation of environmental regulations, and to the detriment of public health.
Al Shamal is the capital city of the municipality of Madinat ash Shamal in Qatar. With the majority of the town's population not yet connected to a sewer network, there was an immediate need to provide a wastewater treatment plant to treat wastewater generated from the towns' population and small industries. Ashghal, the Public Works Authority of Qatar and its end user, decided to install a tanker discharge facility with a compact sewage treatment plant to produce effluent suitable for reuse in irrigation.
As some of you may have heard, LuminUltra has partnered with Microbe Detectives to offer DNA testing services to the drinking water and wastewater industries. So “Who’s on First?” (pun intended); simply put, the partnership’s combined technologies tell you who is in a given water or wastewater sample, and how much is in that sample.
Where there’s a problem, there’s a solution. Sometimes it just takes a little ingenuity to get there. When you’re in the business of providing solutions to municipal and industrial water resource recovery utilities, then it’s helpful to invest in ingenuity.
Recently, ASCE released its Infrastructure Report Card, giving the nation’s drinking water infrastructure a D: in poor to fair condition and mostly below standard. Many water utilities and communities are doing the hard but necessary thing in finding the resources to upgrade their aging water infrastructure. And, for those in earthquake prone areas, hopefully considering an earthquake resistant system.
Calgon Carbon created the first granular activated carbon (GAC) from bituminous coal in the 1940s and has staked a position of global industry leadership ever since.
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).
What’s the best way to fight odors in the wastewater industry? Add a little oxygen. Adding Praxair’s pure oxygen to your existing process can raise the level of dissolved oxygen enough to reduce odors without further action. Even better, the use of a Praxair oxygen acetates treatment system will lower costs and help you meet your environmental goals. Our systems help you manage peak demand and increase capacity while reducing Volatile Organic Compound (VOC) emissions.

We’re entering the home stretch of the 85th Session of the Texas Legislature.
“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.
The Global Cleantech 100 identifies nine innovative water/wastewater technologies set to make significant market impact in the next decade.
In a recent column, Water Online Associate Editor Peter Chawaga wrote about a new plan for drinking water safety in the Trump era. In part, he references a late-2016 U.S. EPA Call to Action to improve the safety and reliability of the nation's drinking water.
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.
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?
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
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 is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.
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.
For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
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.
