Enhanced Biological Phosphorus Removal Evolves With S2EBPR
Leon Downing, Principal Process Engineer and Innovation Leader at Black & Veatch, sat down with Water Talk's Todd Schnick and Kevin Westerling to discuss the exciting developments taking place with sidestream enhanced biological phosphorous removal, or S2EBPR. Black & Veatch is co-leading a Water Research Foundation (WRF) study conducted to establish a standard research approach for S2EBPR, which Downing calls "the evolution of...  Continue Reading..
How New Technology Lowers The Cost Of Ownership For Remote Sites
Whether a utility operates a couple of pumping stations or a couple hundred, driving out to those locations for monitoring and maintenance is labor-intensive and costly.  Continue Reading..
Blower Rentals Offer Tailored Solution To Temporary Needs
There are many reasons for a utility to rent a blower for wastewater aeration. Besides the obvious — an emergency — plant operators may need a rental to bridge the gap during upgrade projects, supply seasonal need to supplement air, or perform testing.  Continue Reading..
Presidential Plans At WEF
Recently appointed Water Environment Federation (WEF) President Jackie Jarrell understands the trials and tribulations of WEF members, and not just from afar. As the deputy director of Charlotte Water, a utility with about 1,000 employees and 800,000 customers, she has firsthand experience with common industry challenges, including aging infrastructure, a retiring workforce, and emerging contaminants of concern such as PFOS. As president of WEF,...  Continue Reading..
Process Intensification And Innovation
Two VPs from Brown and Caldwell stopped by Water Talk to share leading-edge insight on topics important to just about every American utility — doing more with less and innovating for the future. Jose Jimenez, VP of Water Technology and Innovation, notes how "process intensification" can be achieved through gains in energy efficiency, among other ways, and illustrates the impact by sharing real-world results from a Pueblo, CO,...  Continue Reading..
A New Leader And Era For WEF
The Water Environment Federation (WEF) has long led the way for water and wastewater professionals, but now the 35,000-member organization has a new leader of its own — Water Talk guest Walt Marlowe. Fresh off his initiation as executive director on Sept. 9, the executive director sat down to discuss his varied background, his views on the state of the water industry, and his plans for WEF moving forward. He also shares lessons learned...  Continue Reading..
A Modular, Energy-Saving Approach To Wastewater Gaining Traction
A combination of urban sprawl, more stringent environmental regulations, and aging facilities is putting a huge strain on the wastewater operations at many municipalities. The good news is that membrane aerated biofilm reactor technology, also known as MABR, offers a compact and energy-efficient solution.  Continue Reading..
External Solutions To Water/Wastewater Flow Measurement
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..
Advanced Flow Metering Incorporates More Features
As water operations emphasize tighter controls for greater efficiency, the demand for accurate flow metering is becoming more critical than ever. To answer this call, GF Piping Systems has introduced the FlowtraMag, a PVC-bodied, full bore mag meter.  Continue Reading..
An Improved Approach To Water Quality
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..
