OI Analytical’s Eclipse 4660 Purge-and-Trap Sample Concentrator processes samples for GC-MS analysis of volatile organic compounds (VOCs) in drinking water, groundwater, and wastewater samples in accordance with U.S. EPA methods. Patented sub-components in the Eclipse 4660 improve instrument operation, reliability, and analytical performance. A new brochure details design and performance characteristics of the instrument.
The Evolution From Small-Blade To Large-Blade Agitators By Jared Wray, P.E., and Daniel Alper
To appreciate the importance of mixing, it helps to consider the array of products that require mixing as they are made or refined. Stirring with a stick may seem crude, but for an application such as cooking, it is still a state-of-the-art mixing technology. As increasing volumes of material need mixing, larger and more automated mixing technologies are required.
Wastewater Treatment Plant Foils Energy Heist By IPEC
The Durango wastewater treatment facility is a traditional waste-activated system. The biosolids (WAS) is collected from secondary clarifiers, treated with flocculants, and thickened before an anaerobic digestion. A centrifuge had been used for the thickening process, which dewatered the WAS to an 8 percent to 10 percent consistency. The plant had three 50 hp units and used either one or two of the units as needed
Borough Of Monaca Adds Another Brick In Its Road To Sustainability One of the key opportunities for sustainability improvements is located in the Borough’s water system. With a leak-prone, aging system, the Borough knew it needed an upgrade to new, clean technology that would help increase productivity, improve billing accuracy and save money.
Waterfall screens are ideal for effectively removing fibrous and solid particles from a waste stream. An automatic self-cleaning spray bar runs on a timer to continually keep the screen free from debris buildup.
Dif-Jet Aeration Systems feature low cost and high efficiency, and are suitable for industrial wastewater systems to reduce BOD (biochemical oxygen demand) or COD (chemical oxygen demand) and for supplemental aeration.
