Installing flow meters in new piping is one thing. Replacing a 20-year-old meter or adding new metering to piping where it never existed before is quite another. In this Water Talk interview, Cheryl Ades Anspach, marketing manager with Badger Meter, offers a non-invasive alternative using easily retrofittable clamp-on ultrasonic meters offering accuracy to + 0.5 percent and flow rates to 33,000 gpm in pipes up to 48” diameter. Two...  Continue Reading..

Fine bubble diffusers in water treatment operations can be problematic. In addition to their tendency for fouling and gasket failure, they can foster less-than-ideal bromate conditions. Using sidestream injection technology for delivering ozone, by comparison, offers a significant reduction in bromate formation while allowing easy access to key process components for maintenance and eliminating the need for contactor shutdowns.  Continue Reading..

Not all water is the same, so don't be sold on a "one-size-fits-all" solution. Many treatment providers will attempt to fit a square peg in a round hole, while others — a select few, in fact — can provide a fit-for-purpose solution based on broad, customized capabilities. That's the pitch from U.S. Water Services, which recently became part of Japan-based Kurita Water Industries, a resource- and technology-rich...  Continue Reading..

Everyone wants peak accuracy from their instrumentation, but nobody wants to disrupt their field process to verify it. Purvang Upadhyay, the global water industry manager for measurement and analytics with ABB, shared an attractive alternative to such disruption with the Water Talk moderators at WEFTEC 2019 — in-situ verification. This classic example of digitalization in the water industry enables users to check the health and accuracy of...  Continue Reading..

When a company stakes its reputation on delivering innovative technologies, products, and services, the specter of a changing regulatory landscape is considered more an opportunity than an obstacle. In this Water Talk interview, Mirka Wilderer, CEO of De Nora Water Technologies, discusses varying topics such as pharmaceuticals and nutrients in wastewater, the synergy of the company’s new MIOX and Neptune acquisitions, and how to address...  Continue Reading..

When low population density and troublesome topography make traditional gravity sewers cost-prohibitive, septic-tank effluent-pumping (STEP) technology offers an affordable alternative. In this Water Talk discussion, Mike Saunders, market segment leader for engineered systems at Orenco Systems, outlines how to match the right technology to the need. Orenco’s new decentralized liquid-only sewer systems treat septic effluent that is reduced...  Continue Reading..
