John Maziuk, Technical Development Manager at Solvay Chemicals, discusses the benefits of peracetic acid over other wastewater and stormwater disinfection methods, including no harmful byproducts, a simpler process, and a longer shelf life.
Water quality is getting a lot more scrutiny these days. And that’s a good thing says Russ Swerdfeger, Global Director of Memcor Product Management with Evoqua. Alongside his colleague Daryl Weatherup, Director of Marketing with Evoqua, Swerdfeger recently discussed the future of drinking water and the key issues and concerns facing the water industry right now with Water Talk.
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.
Vitamins, steroids and hormones are all emerging as contaminants being detected in drinking water supplies. As Jon McClean, Chief Technology Officer with Neptune Benson explains in this Water Online Radio interview, advanced oxidation processes (AOPs) add hydrogen peroxide in front of UV treatment to eradicate contamination.
Fletcher Roche, Product Manager at Evoqua Water Technologies, explains why chlorine gas is a safe and cost-effective disinfection solution.
Though the company has only been around about a decade, MIOX is making a notable impression on the water and wastewater treatment industry.
Polymer activation through proper hydration of the polymer particle is critical in water clarification or sludge dewatering applications. According to Jeff Rhodes, Vice President of Commercial Development for UGSI Solutions, “the key is to have a high energy zone at the moment of initial welding, when the polymer and the water come together.”
Disinfection can be achieved through chlorine, membranes, ozonation, or UV (among others), but the latter may be best equipped to serve the changing water treatment market.
Bill McDowell of Blue-White Industries, a supplier of chemical metering pumps and flow meters, recently sat down with Water Online Radio and explained the difference between peristaltic pumps and diaphragm pumps.
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.
