Drinking Water Contaminant Removal podcasts

  1. The Value Of Wastewater: Closed Vessel UV Disinfection For Water Reuse
    11/8/2013

    Jon McClean, President of Engineered Treatment Systems (ETS), explains how UV disinfection of wastewater provides an effective and sustainable solution to growing water shortages.

  2. The Pros And Cons Of Ion Exchange Versus Membrane Technology
    10/10/2013

    Frank Caligiuri, Sales Manager for Hungerford & Terry, discusses the merits of ion exchange versus membrane technology with a focus on the constituents being removed

  3. 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.”

  4. UV Examined (Audio)
    8/1/2013

    Adam Festger, Market Manager, Drinking Water and Environmental Contaminant Treatment for TrojanUV, highlights some of advances in UV technology over the last few years including UV groundwater treatment, UV chemical contamination treatment and UV lamp efficiency.

  5. Instantly Measuring Trihalomethanes (THM)
    8/2/2016

    Water treatment plants are responsible for sampling their water quarterly for trihalomethanes (THM). THM are a group of four chemicals that are formed along with other disinfection byproducts (DBPs) when chlorine or other disinfectants used to control microbial contaminants in drinking water react with naturally occurring organic and inorganic matter in water.

  6. 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.

  7. 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.

  8. Coconut Shell Activated Carbon For Removing PFOA And PFOS
    7/8/2016

    Coconut shell activated carbon is typically used for filtration in cleaner waters. Its alternatives are coal-based or wood-based carbon. With the recently published EPA guidelines on perfluorinated compounds, Water Online Radio sat down with Neal Megonnell, Senior Vice President for Haycarb USA, to understand coconut shell activated carbon’s application in fighting PFOA and PFOS.

  9. UVT-LED Sheds Light On UV Disinfection
    10/28/2015

    Learn why measuring UV transmittance is so important to efficient disinfection, and how LED helps get you there.

  10. The Evolution Of Low-Energy UV Disinfection
    8/13/2014

    Conventional ultraviolet (UV) disinfection is a great, but often expensive, solution for the destruction of pathogens in drinking water. All those lamps and power emissions add up. But what if you could perform the same job with 1/10 of the power used by conventional systems?
