Drinking Water Disinfection Podcasts

  1. Upcoming Tech: Alternatives To Coal-Based Activated Carbon, Magnetite Ballasted, And More

    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.

  2. 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.

  3. Safer Disinfection With Peracetic Acid

    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.

  4. Disinfection Using Calcium Hypochlorite

    Calcium hypochlorite is one method of disinfecting water and wastewater. In this Water Online Radio interview, Lou Finelli, Municipal Key Account Sales Manager for Lonza, compares calcium hypochlorite with other disinfectants such as chlorine gas, sodium hypochlorite and UV.

  5. Is UV Poised For Increased Adoption?

    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.

  6. LA Story: Advanced Treatment, Reuse Saves Scarce Water Resources

    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.

  7. Ozone: An Emerging Star For Disinfection

    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.

  8. UV-LED Technology: The Latest In Disinfection

    Dan Shaver, Business Development Manager at Aquionics, talks about the advantages of UV-LED technology for disinfection: low energy requirements, chemical-free and customizable design, and proficiency in solar or battery-powered applications.

  9. Drumming Up Chemical Injection

    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.”

  10. A True Lifesaver: Grundfos Provides Key Element For High-Quality Water

    The facilities run by the University of Iowa Hospitals & Clinics have strict standards for water quality, as staff must protect the very sensitive equipment and patients under their care. Safeguarding against such threats as Legionella, there is no room for treatment system downtime. As maintenance issues with the network's existing water treatment systems became ever-increasing, a new technology was sought.
