Drinking Water Contaminant Removal podcasts

  1. Will Peracetic Acid Replace Chlorine?
    10/20/2015

    Chlorine has long been a water treatment staple, but it’s not without its complications. As an alternative, some treatment facilities have been turning to peracetic acid (PAA) and enjoying several key advantages.

  2. 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.

  3. A True Lifesaver: Grundfos Provides Key Element For High-Quality Water
    10/18/2013

    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.

  4. 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.

    When Vinny Gupta, the president and CEO of InNow LLC, met Rich Cavagnaro, the CEO of AdEdge Water Technologies, he saw an opportunity to help 40 million people get clean water.

  6. 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.”

  7. UV Disinfection With LEDs
    11/10/2014

    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.

  8. Fostering Innovation From Within
    7/3/2017

    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.

  9. Lighting The Way: Next Steps For UV Disinfection (Audio)
    6/23/2015

    With more than 8,500 municipal installations over 40 years, TrojanUV is well-versed in UV disinfection. What’s next for the technology?

  10. Ozone: An Emerging Star For Disinfection
    11/12/2014

    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.
