For 15 years, plans to double the capacity of Michigan’s Zeeland Clean Water Plant remained stalled as the City of Zeeland worked toward a joint wastewater treatment contract with two neighboring Ottawa County communities. As a result, maintaining efficient aeration control posed a challenge for the 1.65 million gallons per day (MGD) facility. When expansion plans moved forward in 2016, the city alleviated those problems with the Xylem Sanitaire CASPERON activated sludge solution process, which eliminated the use of lime to treat waste and significantly reduced the volume of biosolid residuals.
A pesticide manufacturing plant in Gujarat, India produces up to 6,000 metric tons per year of various pesticides for agricultural use.
Title 22 of California’s Water Recycling Criteria is among the strictest water treatment standards for water recycling and reuse in the United States. Fluence’s MABR demonstration plant was installed at the Codiga Resource Recovery Center (CR2C) in Stanford, California, in January 2018 for the purpose of third-party evaluation. The testing parameters included criteria to evaluate reliable enhanced nutrient removal in the form of Total Nitrogen, which is increasingly important across the United States and difficult and costly to achieve through conventional wastewater treatment.
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.
The Prince William County Service Authority carefully considers its impact to the environment when conducting wastewater treatment.
About an hour south of Atlanta, the city of Barnesville, Georgia is a town of shady, tree-lined streets, a fondness for celebrating its history, and a sharp eye on the future.
The successful management of the world’s marine environment has unique challenges when compared to land based environments. The oceans encompass a huge area to manage, their political boundaries are blurry, and conditions in one small area can have serious impacts on much larger, far removed areas.
In municipal or industrial wastewater treatment applications, steel constructed tanks up to 5.0 million gallons per day (MGD) and below offer significant advantages over concrete; benefits that lead to lower operating and lifetime costs, regardless of application.
We approach challenges holistically to create cutting-edge, customized solutions. A crucial first step in this process is real world field testing. Why? Because distinct rubber compounds react differently in distinct waste streams. Given the unique chemical makeup of any waste stream, we can optimize rubber compounds, and by testing it in your unique application, we can design the proper aeration diffuser membrane materials needed for optimal performance and energy efficiency.
Disposable, throw-away products are making raw sewage pumping tougher than ever. The Jefferson Street Pump Station at the City of Centralia, WA had a problem demanding a cost-effective solution.
Compliance and consistent high quality are two of the key goals within the beverage industry. Hach® provides support for these goals through comprehensive analyses of water and beer.
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.
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.
A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
Peracetic acid (PAA) is one of the most versatile and widely used disinfectants on the market. PAA has proven to be an excellent sanitizer and disinfectant in the food, beverage, cosmetic, pharmaceutical, and agriculture industries for industrial water treatment, as well as an excellent disinfectant for use in the wastewater treatment industry.
Ultrafiltration systems can be engineered and designed in several possible combinations based on the application and source water quality. There are different membrane materials, membrane shapes, flow types, and configurations.
An inherent vertical of the global specialty chemicals space, hypochlorite bleaches market has been observing remarkable popularity of late. With rising incidences of infectious illnesses on a global scale, the demand for disinfectants, bleaching, and sanitization products is likely to accelerate. Hypochlorite bleaches are popular disinfection products with the ability to terminate a vast array of disease-causing bacteria, fungi, viruses, and fungi, provided they are used with adequate precautionary measures and adhere to specific usage guidelines.
Which process should you choose for your application?
I have been in the waste treatment business for some years now, and I am continually surprised with what I see promulgated by the people that do this every day and should know better. Out West (Texas, actually), we see life as a more or less continual struggle with all kinds of adversaries. Collectively we call them varmints, and they are ever present as we go about our daily duties. There is much to be learned from folklore in establishing a common-sense perspective, and the convergence of Texan culture and waste treatment technology (and even water treatment) are cases in point.
The movie and sports term has infiltrated the business world and has important implications for the water/wastewater industry.
