Advanced treatment solutions continue to evolve as 1,4-Dioxin, N-Nitrosodimethylamine (NDMA) removal and Pharmaceuticals and Personal Care Products (PPCPs) appear on the regulatory horizon. Many times, advanced treatment requires combinations of different products in the treatment process.
Every water treatment challenge is a little different. Many companies have a variety of technologies that can be applied to meet the demands of their water utility customers. One such company would be SUEZ. Water Talk recently sat down with Adriano Vieira, Director of R&D with the SUEZ IDEAS Center, to learn more about the unique approach the Company’s North American arm is taking to innovation.
Over the past two years, no groundwater issue has perhaps received as much community focus and attention as polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS, often referred to as perflourinated compounds (PFCs). The U.S. EPA issued a health advisory, limiting the amount of these compounds to 70 parts/trillion which kicked off a nationwide evaluation of local water sources.
There are many places around the country where water shortage is a big issue. Water is the most precious resource we have, and in light of the shortage, people have started trying to investigate creative ways of ‘what’s my next water resource,’ Chris Milligan, vice president, director of engineering with BlueInGreen, told Water Online Radio in an interview.
When it comes to gas injection, it pays to work with an experienced manufacturer that has lived the ups and downs of moving from pilots to full-scale plants. A number of years ago, Mazzei Injector Company ran into an issue where the engineer had specified a system at 2 psi of water pressure.
In this Water Online interview, Paul Rice of Evoqua talks about the company’s variety of technologies which span across a wide range of water treatment solutions. One highlight is Evoqua’s AquaCarb CX, a coconut shell-based activated carbon that offers an alternative to coal-based activated carbon for removing disinfection byproducts, tastes, and odors.
Adam Festger, Drinking Water & Environmental Contaminant Treatment market manager for TrojanUV, sat down with Water Online Radio to discuss UV trends and technologies. Hear all about TrojanUV’s “Let’s Talk Adenovirus” campaign, as well as the company’s growing installation base and recent product developments.
UV LEDs offer the chemical free disinfection of traditional UV while avoiding mercury lamps. In certain applications where customers are concerned about the potential hazards of mercury contamination in the water from a broken lamp, UV LEDs are interesting because they don’t contain any mercury content at all.
Back in 2014, Louisiana’s Department of Health and Hospitals wrote an executive order for municipalities to boost their chlorine residuals as high as possible to burn off all biofilm and stop the outbreak of brain-eating amoeba (Naegleria fowleri) that had been detected as the cause of death in a number of individuals.
Jon McClean, President of Engineered Treatment Systems (ETS), explains how UV disinfection of wastewater provides an effective and sustainable solution to growing water shortages.
