Not cool enough in summer. Not warm enough in winter. Guests staying at a prestigious country club in New York state complained regularly about the air conditioning and heating of their luxury suites and apartments. By Martin Dingman, Product Manager, Siemens Industry Inc.
Inland Empire Paper Company (IEP), located in Millwood, WA specializes in the production of newsprint paper using a combination of mechanical pulp and recycled newspaper pulp. IEP produces an average of 525 tons per day of newsprint and specialty paper products in 20 to 40 pound weight paper.
Sims Bayou begins near Missouri City, TX, and meanders northeast until it reaches Buffalo Bayou.
While regulations demand that wastewater treatment plants get nutrients out of the water, the world’s food supply may demand more — that we recover and reuse them.
Pumps and pumping systems are like unsung heroes of modern society – quickly and quietly transporting vital water supplies, chemicals and waste to and from locations, which rely upon their consistent, reliable operation.
When a series of water crises in 2014 disrupted conventional utility services in the coastal Argentine city of Caleta Olivia, the city needed a way to ensure an uninterrupted water supply.
America’s drinking water and wastewater systems face increasing challenges in maintaining and replacing their pipes, treatment plants, and other critical infrastructure. Prolonging and renewing the nation’s high-quality water services requires a clear sense of what is a sustainable water infrastructure, the amount of investment needed to create and preserve it, where investments should be made, and by whom. In 2008 and 2009 the Aspen Institute convened a multi-stakeholder dialogue to help provide clarity and promote leadership on these issues. By The Aspen Institute
A public works director in southern Kalamazoo, MI, recommended the county investigate new generation Flygt brand pumps for five troublesome singlephase stations along their system.
Given numerous variables when selecting an aeration blower system for wastewater applications, and equally numerous claims by technology providers, it is not surprising that confusion exists. Worse than confusion is the disappointment that results when a blower technology fails to perform as anticipated — and operating cost and efficiency benefits go unrealized.
The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.
This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.
As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.
Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.
Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.
Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.
With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.
A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
Any operator will tell you that a treatment plant is only as good as its equipment. That means employing the devices with the longest lifespans, the lowest operating costs, and the most intuitive designs is critical.
Chicago is giving its oldest wastewater treatment facility a disinfection facelift and using the world’s largest reservoir to curb combined sewer overflows.
XP Solutions in Brisbane recently presented a webinar on the design of detention basins. In response to the session, the support team were asked a number of questions on some of the other options that are available to engineers and designers of these systems as well as specific requirements that may need to be addressed. The following items apply within the Australian context but are applicable across the world.
There is a name for your organizational structure, even if you've never given it any thought. But knowing it can help you determine your career path options. Perhaps you work in functional structure - or maybe a matrix.
In the summer of 1864, French chemist Louis Pasteur was vacationing in the small eastern town of Arbois where he found the local wines too acidic for his palette.
Sustainable approaches to stormwater management are taking hold around the world. One example is the European Union Horizon 2020 funding for Nature-based solutions for climate and water resilience in cities (urban re-naturing) – launched today.
