Filtration has been around for a long, long time, so it may be that most treatment plant operators feel pretty informed about its capabilities. But hearing from Brian Frewerd, Director of Application Engineering with Parkson Corporation and Water Talk guest, will likely prove enlightening. Frewerd provides background on sand filtration for tertiary treatment applications, followed by insight on notable technology improvements and performance milestones
Many wastewater treatment plants (WWTPs) are facing stricter limits on nutrient discharges, yet each plant and situation is different and solutions are not one-size-fits-all. Bryce Figdore, Wastewater Process Engineer with HDR and Water Talk podcast guest, talks about another tool at utilities' disposal — nitrification bioaugmentation using granular sludge.
Carollo Engineers, an environmental engineering firm that specializes solely on the planning, design, and construction of water and wastewater facilities has identified five major trends in the industry.
At WEFTEC 2016, Evoqua Water Technologies explored six core challenges faced by wastewater treatment plants -- energy reduction, nutrient removal, odor and corrosion control, aging plant equipment, water reuse and disinfection. In this Water Online Radio interview, Paul Rice, Municipal Marketing Director with Evoqua Water Technologies, discusses energy reduction and nutrient removal in more detail.
Since 1969, Aqua-Aerobic Systems, Inc. has been a leader in the design, application and manufacture of wastewater treatment equipment and systems for municipal and industrial markets, worldwide. They are most noted for the Aqua SBR, the sequencing batch reactor, biological process, as well as now our cloth media filters.
Phosphorus recovery from wastewater and a newly-developed algae product that doesn’t require photosynthesis are the latest examples of intense product development within Ovivo. In this Water Online radio interview, Jim Porteous, Ovivo’s Vice President and General Manager, explains some of the changes he is seeing in the industry that are fueling the Company’s focus for the future.
As the industry’s most common and affordable method, biological treatment lies at the heart of the wastewater cleaning process. Treatment plants harness the power of nature by utilizing organisms that accelerate nutrient removal, eliminating carbon, nitrogen, and phosphorus.
Cold temperatures add another layer of challenges to nutrient removal. In this Water Online Radio interview, Martin Hildebrand, the president of Nelson Environmental, talks about the cold temperature applications in Canada and how new technology can help.
The name “wastewater” doesn’t accurately describe water that has been used, says Jim Porteous, from Ovivo.
Understanding exactly how much of each chemical is needed is critical. Too much, and chemicals and money are wasted, too little, there is a risk of not being in compliance with regulations.
