Expect to see more solar arrays sitting atop waterways.
The environmental problems caused by single-use plastic water bottles continue to make headlines, but that hasn’t slowed down water-related business ventures.
After roaming the oceans for more than a half billion years, jellyfish may finally be poised to overtake Earth’s largest bodies of water.
The presence of dissolved solids presents both physical and financial challenges for aeration diffusers in any wastewater treatment operation and can be particularly problematic in high-concentration industrial and food-processing applications. Here are some warning signs, insights, and solutions for coping with conditions that can lead to excessive dissolved solids accumulation.
Managing the treatment of wastewater — especially industry-generated wastewater that can elevate dissolved oxygen (DO) demands far beyond those of municipal/residential applications — is hard enough. Trying to do so during upset conditions is enough to put any water treatment professional on edge. Here are several preventive and remedial options to keep in mind before or after DO readings go haywire.
On the afternoon of May 19, 2011 KLa Systems was contacted by one of their customers located in Virginia. The customer stated that their aeration basin was running at near 0 mg/l dissolved oxygen (DO) residual with their air supply blowers running at 100% of capacity. Based on the conversation it was determined that a KLa field service technician was needed on site immediately.
Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for sustaining the appropriate air bubble size and distribution needed to achieve dissolved oxygen (DO) requirements for neutralizing high biochemical oxygen demand (BOD) in many industrial and food processing wastewater applications.
A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O2, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O2 to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.
What do a drinking establishment and an eco-friendly writing utensil have in common? They both reflect new and unconventional ways that water is being injected into commerce.
Several advancements in solar technology may provide the answer to drinking water production in distressed regions of the world.
Too many dog owners think their pets’ waste easily breaks down in nature and is helpful to plants, so they leave it on the ground. The truth is that dog poo and other pet waste is loaded with germs such as e. coli and giardia that make people sick as well as nutrients that can fuel problematic algae blooms.
As with any industrial process, the right tool for the job depends on the nature of the task at hand. In aerobic wastewater treatment, that optimal choice often comes down to a balance between the biological and financial demands of the application. Either way, here are several performance comparisons of how multiple aeration methods and locations stack up in industrial wastewater treatment applications.
Aeration for industrial and municipal wastewater treatment involves more than simply moving volumes of air through a treatment basin. It really comes down to creating and sustaining an optimal oxygenated environment for microorganisms to convert oxygen consuming compounds into CO2 and water. Here are some key considerations for making better retrofit decisions about upgrading existing basin capacity and efficiency with jet aeration.
Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.
Looking for a way to store massive amounts of excess green energy? Water may provide the answer.
The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Instead, consider comparing the physics of different aeration technologies and the relative costs associated with them. Here are five major categories for evaluating industrial wastewater aeration efficiency.
It took decades to solve the mystery of Garfield phones that were polluting French beaches. Turns out a load of the novelty item, modeled after the popular orange cartoon character, was slowly being purged from a shipping container that had been lost at sea. That begs the question: Are shipping containers like these polluting global waterways at alarming rates?
Long thought to be an issue that plagued the United Kingdom most acutely, the scourge of fatbergs has been making itself known stateside.
An unusual culprit has been identified as the source behind rotten smelling water in Austin, Texas. Though the source of the smell was surprising, at least it wasn’t too difficult to deal with.
The fallout from Flint, Michigan’s lead-contaminated drinking water has been far-flung and long-lasting.
Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying. As you can imagine, much of the difference is to do with population size and geography.
Did you know that the Environmental Protection Agency (EPA) had a published Contingency Plan in anticipation of the current government shutdown? I guess in hindsight, you would have expected it for an agency with 134 facilities dotted across the country. And in fact, it’s required by the Office of Management and Budget (OMB) under Circular A-11, Section 124 that all government agencies have plans for an orderly shutdown “in the event of an absence of appropriations.”
The federal government recently released its fourth National Climate Assessment which focuses on the impact climate change will have on the U.S. economy over the next century. As mandated by the Global Change Research Act of 1990, the U.S. Global Change Research Program takes a comprehensive look at climate change and its effects on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems and biological diversity.
According to the U.S. Geological Survey, groundwater supplies half of all drinking water to the U.S. population, nearly all of it to our rural population and over 50 billion gallons per day for agricultural needs. But according to new research out of UC Santa Barbara, supplies may be more limited than previously thought.
Last month, The Ocean Cleanup launched its first plastics cleanup system (System 001) in an area of the Pacific between Hawaii and California named the Great Pacific Garbage Patch. It constitutes the world’s largest accumulation zone, known as a gyre, of ocean plastics. Boyan Slat, CEO of The Ocean Cleanup, estimates that half of the Great Pacific Garbage Patch will be removed from the Ocean within five years as additional systems are applied until it achieves full-scale deployment.
Five years ago, the city of Detroit, MI, filed the largest municipal bankruptcy in U.S. history at an estimated $18 to 20B. At the time, there was a lot of speculation in the water market as to how the city would continue to serve its citizens with viable water and sanitary sewer services. Ultimately Detroit reached a deal with neighboring Oakland, Wayne, and Macomb counties to create the Great Lakes Water Authority (GLWA), a new regional water and sewer authority. Spring forward to today and despite Detroit’s population continuing to dwindle, it’s water and sewer provision under the GLWA has recovered significantly.
When you think about areas of the world where people have limited access to clean water, I’m guessing hot, sunny, arid climates come to mind. In an interesting twist, a couple of innovations are using those exact conditions to create potable water.
The latest disposable causing a stir in the wastewater treatment world is the contact lens. Researchers from Arizona State University recently presented their findings at an American Chemical Society event showing that contact lenses flushed down the toilet or washed down the drain can pass through wastewater treatment plants and accumulate in sewage sludge. As sludge is often applied on land for disposal and fertilizing, macro- and microplastics from lenses enter terrestrial ecosystems.
Recently, Ohio Governor John Kasich issued an executive order allowing the Ohio Department of Agriculture to set requirements for storing, handling and applying manure as well as nutrient management plans in an effort to reduce nutrient pollution and algal bloom growth in Lake Erie. The order is set to affect 7,000 farms across 2 million acres.
The annual Lake Erie harmful algal bloom forecast was recently released by the National Oceanic and Atmospheric Administration (NOAA), predicting that western Lake Erie will experience a harmful algal bloom (HAB) of cyanobacteria this summer. The bloom is expected to be smaller than in 2017 but larger than the bloom in 2016.
Sniffer dogs have been used for a while in the oil and gas industry to find leaks. But recently, dogs have begun to be used to find leaks in water mains.
For most of the United States, we’ve reached the time of year where Americans desire to maintain a perfectly green lawn starts to be tested by the warmer and dryer summer months. From the water industry’s perspective, it’s staggering just how many billions of gallons of treated water ends up being sprayed across our hallowed front and back yards in maintaining a full and aesthetically-pleasing lawn.
Jet aeration systems are extremely efficient due to their high alpha factor and clean water oxygen transfer performance. Proper start-up, operation, and maintenance will ensure reliable service and a long life.
Conserving energy and saving costs are always on the minds of wastewater professionals. Aeration accounts for more than 50 percent of electrical usage at most treatment plants. Improved aeration efficiency will always work toward the goals of saving energy and reducing operating costs.
As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.
A couple of weeks ago, Environmental Protection Agency (EPA) administrator Scott Pruitt called PFAS groundwater contamination “a national priority” and pledged action at an EPA national PFAS leadership summit.
Writing for Mental Floss in 2015, Emily Becker finished her article on the twenty-year export of New York City’s wastewater sludge to Colorado with the words “there are no plans for the New York City poop train to leave the station again.” Fast forward to 2018 and the wheels are once again rolling.
It is almost too heart-breaking to watch. In the YouTube video, marine biologists from Texas A&M University extract a plastic straw from a sea turtles’ nose as the creature winces in pain. Today that video has been viewed more than 22 million times, drawing attention to the hazard that plastic straws present to animals and our environment.
Saturday, March 24th was a busy day at the Brightwater Clean-Water Treatment Facility in Woodinville, WA, just outside Seattle. The Utility’s Education and Community Center was full of family-oriented science experiments and art projects with organized tours of the wastewater treatment plant taking place throughout the day. All in recognition of International World Water Day which had occurred two days before.
For many people, hot springs conjure up thoughts of cleansing and purity. For centuries, humans have visited hot springs to relax and recover. But as with any natural water body, hot springs can also exhibit biota that can infect and in severe cases kill.
Aeration is the heart of every activated sludge system, as well as the most energy-intensive process. When designing or modifying a wastewater treatment facility, the aeration system design will have lasting impacts on effectiveness, capital and operating costs.
Last year, the National Oceanic and Atmospheric Administration (NOAA) recorded the largest hypoxic zone in the Gulf of Mexico since monitoring began 32 years ago. Hypoxic waters, often referred to as dead zones, have dissolved oxygen concentrations of less than 2-3 ppm. They are caused by eutrophication or excess nutrients that promote algal growth in water bodies. As algae decompose, they consume oxygen creating dead zones.
You may have read recently that Orange County Water District (OCWD) and Orange County Sanitation District (OCSD) set a Guinness World Record for the most wastewater recycled to drinking water in 24 hours. The record attempt kicked off on February 15th 2018 to mark the 10th anniversary since the districts’ Groundwater Replenishment System was launched and culminated with more than 100 million gallons per day (MGD) being produced.
Sequencing Batch Reactors (SBRs) are a variation of the activated sludge process that combine treatment steps into a single basin. Based on a fill-and-draw method, major phases of the SBR process include a cycle of fill (with or without aeration), react, settle, decant, and idle. Today, successful flow control strategies have made SBRs state-of-the-art technology. SBRs are commonly used today and are especially beneficial for many industrial applications.
Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.
One of the great turnaround stories in the history of our nation’s water bodies is that of the Chesapeake Bay. Since 1976 when the Environmental Protection Agency (U.S. EPA) first undertook a comprehensive study of the Bay, efforts to address excessive nitrogen and phosphorous degradation of water quality have steadily improved the Bay’s complex ecosystem.
When California’s AB2022 went into effect earlier this year, allowing the bottling of advanced purified reused water for educational purposes, Orange County Water District (OCWD) and Orange County Sanitation District began the #GetOverIt! campaign to continue to push for consumer acceptance of recycled water systems.
Unless you spent the last election cycle hiding under a rock (and no blame if you did), you are no doubt aware of the growing rift between the two major political parties of the United States. As reported in The Atlantic citing polling from the Pew Research Center for the People and the Press, those who identify as Democrats are becoming more liberal and those identifying as Republicans swing ever more conservative.
Weather plays an important role in how Americans think about water. And I don’t mean when it’s raining, we decide to grab a raincoat.
It wasn’t so long ago that city rivers were some of the more polluted bodies of water on the planet. In 1969 for example, the Cuyahoga River famously caught fire after years of unabated pollution, spurring an environmental movement to clean up the nation’s waterways.
