Drinking Water Contaminant Removal podcasts

  1. 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.

  2. 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.

  3. Fostering Innovation From Within

    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.

  4. Groundbreaking Groundwater Treatment

    Carollo Engineers and AdEdge Water Technologies share insight and expertise while bringing innovative groundwater treatment systems to market.

  5. UV Disinfection With LEDs

    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.

  6. Coconut Shell Activated Carbon For Removing PFOA And PFOS

    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.

  7. Getting Chlorine Disinfection Right

    Of all the process considerations facing wastewater treatment operators, disinfection is one of the most important. In this exclusive Water Talk interview, Gary Lohse, Technical Sales Manager, Disinfection with De Nora Water Technologies, discusses how disinfection has become increasingly complex over time. Lohse reviews a host of selection criteria including target microorganisms, control strategies, disinfection by-products, capex and safety.

  8. The Value Of Wastewater: Closed Vessel UV Disinfection For Water Reuse

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

  9. Experience Pays Off For Gas Injection

    When it comes to gas injection, it pays to work with an experienced manufacturer that has lived the ups and downs of moving from pilots to full-scale plants. A number of years ago, Mazzei Injector Company ran into an issue where the engineer had specified a system at 2 psi of water pressure.

  10. Treatment Alternatives For PFCs

    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.
