With the introduction of new measurement technologies and the myriad of performance claims from sale literature, it’s easy to lose sight of the important elements that an effective flow meter offers no matter what technology is used. Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.

Communities are facing decisions on how best to upgrade aging stormwater infrastructure and build new  infrastructure to lessen the impacts of stormwater runoff. As communities make these decisions, they need tools to assess their options in order to determine the most cost-effective approach.

Written by Kaeser’s system experts, this white paper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy efficient system.

Bose Cascade’s Ft. Frances, Ontario kraft mill operation faced a wastewater treatment problem due to dead spots in nearly half of its aerated stabilization basin. Newterra's Aire-O2 came to the rescue.

The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.

Many owners and operators of traditional decentralized municipal wastewater treatment plants, also referred to as on-site or off-grid treatment, are acutely aware their systems are at risk of becoming obsolete.

Business people love to talk about "disruption." They pride themselves on eating their competitors' lunch. Where their markets used to be about raving fans, now it's about inspiring craving fans, fueled by "hunger marketing" and the fear of missing out. There's a lot of dog-eat-dog philosophy...which is why it's important for companies to be willing to cannibalize their own technologies.

In this case study, read about a successful pilot test in Long Island, New York, removing 1,4 dioxane from water. The technology used offers improved efficiency, reduced maintenance, and ongoing monitoring for reliable water treatment.

Find out how a treatment plant upgraded its secondary treatment aeration system to include nutrient removal through a nitrification/denitrification/phosphorus process and has successfully processed I&I induced surges that reached a 10-MGD peak.

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached

In this application note, explore considerations for achieving more reliable accuracy when quantifying dechlorination results for applications ranging from RO membrane protection to wastewater discharge compliance.

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.

A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.  

In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.
