Though the current U.S. EPA administration is boasting about its action to clean up the nation’s Superfund sites, it appears that it has not done as much as implied.
With cuts being made to the budget of the federal EPA, individual states are having to step up and take matters of protecting drinking and source water into their own hands. Last year, none were more forceful with this change than Ohio.
As the U.S. EPA is reshaped under President Trump, some are concerned over what has been reported as an “exodus” of employees from the agency.
One of the nation’s most high-profile water contamination cases has drawn federal interest, as the U.S. EPA joined an investigation into perfluorinated compound (PFC) pollution in Michigan.
Wastewater pros are using diet soda to track down pollution.
As perflourinated compound (PFC) contamination continues to raise concerns all over the nation, one Michigan community has decided to take action to combat it.
Wastewater treatment facilities use multiple processes and a variety of equipment to produce water clean enough for reuse. Each process within the treatment train may serve a different function yet use the same or similar equipment. In such cases, standardizing equipment may be beneficial.
Wastewater treatment plants use numerous pumps in a variety of types and sizes to move water through the process. Depending on plant configuration, they may pump influent, activated sludge, thickened or digested sludge, biosolids, scum, filtrate, effluent, or reuse water. Each matrix has specific characteristics that engineers consider when designing pumping systems.
It’s the call no water treatment plant superintendent wants to receive, especially not while on vacation. Andy McClure, Superintendent of Toledo, Ohio’s Collins Park Water Treatment Plant, answered his phone to hear his head of operations report that the level of microcystin in the finished water was high, caused by a large harmful algal bloom (HAB) that was impacting the plant’s Lake Erie intake.
Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.
The fourth and final introductory video of the series, follows how biosolids are treated throughout the process. Reviewing thickening, aerobic and anaerobic digestion, dewatering and drying. An introduction to wastewater treatment unlike any other out there.
Activated sludge systems have been a cornerstone of wastewater treatment for over 100 years. This biological process uses suspended growth microorganisms to break down and consume organics and remove nutrients from the wastewater. The heart of the process takes place in aeration basins, where the microorganisms need to receive sufficient oxygen to stay alive.
Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.
A deep dive into reverse osmosis (RO) elements reveals the importance of feed channel spacers for optimal membrane filtration system performance.
The Monster Wash Press is JWC Environmental’s latest generation of washer compactors. The Monster Wash Press processes screenings to separate water and organics from the solids. The result is a clean, dry, light and compact discharge which reduces the amount of waste to be dumped, ultimately saving treatment facilities time and money.
Until recently, multi-stage centrifugal blowers and gear-driven single-stage turbo blowers have dominated larger wastewater treatment plant (WWTP) operations. Turbo blowers in the 50 hp to 300 hp range have historically been popular for their low total lifecycle cost in mid-range WWTP applications (from 1 MGD to 20 MGD).
PFC contamination is the number one drinking water issue today. So how are local and federal leaders working to put an end to it?
Last year was full of twists and turns for the drinking water and wastewater treatment industries. What can 2017’s biggest stories tell us about what’s to come this year?
Though some preliminary regulations have taken place to curb the presence of microplastics in the environment, more research is needed to determine what role wastewater treatment plants can and will play in solving the problem for good.
With water treatment plant operators around the country relying on paper and pen to record critical quality data, there is an opportunity to make life easier online.
As excess nutrients continue to pollute source water, bringing dead zones and toxic chemicals, it’s time for the disparate agencies that can make a difference to band together.
The New York City Department of Environmental Protection has compiled a report on the world’s leading stormwater management solutions and challenges. Reviewing its contents can be an opportunity for communities to build stormwater strength together.
Cities all over the country have been prioritizing clean water through a variety of different programs and the City of Brotherly Love is among the ranks.
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.
It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.
It’s no secret that municipalities across the country are facing budget constraints.
California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.
To help drive sales, producers of biosimilar medicines seek to gain as much pricing advantage as possible over their products’ reference biological medicines while maintaining as much profit margin as they can. That’s why they are always looking to minimize production costs, especially in raw materials and labor, their largest cost components. While the costs of the former depend on market prices and a buyer’s negotiating skills, the latter can be best reduced through automation and continuous processing.
Affordability and maintainability are two of the greatest challenges small municipalities face when constructing and managing sewer infrastructure. With these challenges in mind, it’s important for small cities to choose wisely when investing in a wastewater system that needs to last for 30-60 years.
A Request for Startups post on January 3rd on the Y Combinator Blog caught my eye. The blogger talked about the need to prepare for things to get worse with regard to climate change, and called for applications for funding from those working on new technologies that could inexpensively produce clean water.
More than 20 years ago I wrote a Master’s Thesis about software tools that could be put together with EPA SWMM to create a toolbox for very long term continuous simulation for stormwater and watershed simulations. I was inspired at the time by Dr. William James who was my advisor for that research.
Salvator Mundi sold for nearly half a billion dollars. Walter Isaacson’s latest biography is a breakaway hit. Management guru Michael Gelb’s book accessing the thought techniques of history’s most accomplished Renaissance Man — in every literal and figurative sense of the word — is still a bestseller. Almost 500 years after his death, Leonardo da Vinci is still a superstar.
Conversation at the 2016 SESWA Stormwater BMPs, LID and Green Infrastructure Seminar in Atlanta GA that I attended recently touched upon the idea of computers taking our jobs and ‘Engineering Bots’. This has of course happened in other industries, but I didn’t anticipate it happening in the stormwater planning, design and management world.
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.
Straight pipes, failed drainfields, polluted lakes, out-of-compliance discharge permits, and several other indicators of wastewater management issues are widespread throughout Iowa’s rural communities. By Tyler Molatore, Orenco Systems®, Inc.
For a 24-hour-a-day, seven-day-a-week water and waste water management operation, having a supervisory control and data acquisition (SCADA) system is a must. A SCADA system should make workers’ jobs easier, but if it’s not working properly, or it’s unable to keep up as the enterprise expands and upgrades its processes, it becomes a hassle to deal with.
Now that you have returned to the role of private citizen — though, admittedly you are a private citizen with millions of eyes focused on you — I want to encourage you to continue your great work promoting the health of our nation’s children. Your emphasis on exercise and nutrition, jobs and support for veterans, and education have touched millions of Americans of all ages and all backgrounds. Now it’s time to bring in the most common denominator and the first step toward good health — access to clean water.
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?
This blog is a summary of a presentation I gave at the Water Quality Association’s annual convention in Orlando.
Talk about making waves. Cryptocurrency — digital “tokens” or “coins” rooted in computer code and valued for the very fact that they are disconnected from governments and banks — have experienced spectacular rises and falls in recent months. The crypto-economy is already worth hundreds of billions of dollars (REAL dollars!), and it’s anyone’s guess how fast it will grow after that.
