Drinking Water Disinfection Podcasts

  1. Understanding The Benefits Of Chlorination
    10/4/2013

    Fletcher Roche, Product Manager at Evoqua Water Technologies, explains why chlorine gas is a safe and cost-effective disinfection solution.

  2. On-Site Generation: A Green Technology
    6/23/2015

    John Deogracias, a Commercial Leader with the Parkson Corporation, sat down with Water Online Radio at ACE15 to discuss the MaximOS product line, which uses a patented, award-winning technology of on-site generation.

  3. Treatment Alternatives For PFCs
    7/4/2017

    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.

  4. Helping Chlorine Out During The Disinfection Process

    If you’re still unfamiliar with the name De Nora, it’s time to get acquainted. Traditionally a supplier of plates for electrolytic industries, the company purchased Severn Trent’s equipment business in 2015 and is investing in its core business of disinfection and filtration.

  5. PAA And UV Pair Up To Improve Disinfection Performance
    10/26/2016

    Peracetic acid (PAA)-based disinfection is growing in the US, both as a standalone disinfection method and in conjunction with other applications such as UV. Water Online Radio sat down with John Maziuk, Technical Development Manager with Solvay Chemicals to understand why.

  6. Polymer Activation And Onsite Hypochlorite Generation
    11/3/2016

    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.”

  7. Safer Disinfection With Peracetic Acid
    1/10/2014

    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.

  8. Drumming Up Chemical Injection
    10/24/2017

    The operating ranges for chemical injection need to be large because of the variability of flow in many treatment operations. As Bill McDowell, Vice President of Operations with Blue White Industries explains in this Water Talk interview, “You might be down to as low as 5 or 10 milliliters a minute and then one hour later; you might need to pump 15 gallons a minute out of the same pump and through the same sensor.”

  9. On Site Hydrogen Peroxide Generation for Advanced Oxidation Process
    7/6/2016

    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.

  10. LA Story: Advanced Treatment, Reuse Saves Scarce Water Resources
    9/24/2015

    Officials in Los Angeles have grown tired of importing water, which is an expensive, unsustainable response to the region's persistent drought. The smarter solution, they concluded, is to reuse local resources through advanced purification and aquifer recharge. But how do you ensure safety and efficiency before committing to a treatment technology? A unique piloting tool from Xylem’s Wedeco brand offered the city clear answers.
