Drinking Water Contaminant Removal podcasts

  1. Microbial Contamination Monitoring For Water Distribution Systems
    7/5/2017

    Back in 2014, Louisiana’s Department of Health and Hospitals wrote an executive order for municipalities to boost their chlorine residuals as high as possible to burn off all biofilm and stop the outbreak of brain-eating amoeba (Naegleria fowleri) that had been detected as the cause of death in a number of individuals.

  2. Advanced Water Treatment Solutions To Solve The Modern Treatment Puzzle
    6/25/2014

    Advanced treatment solutions continue to evolve as 1,4-Dioxin, N-Nitrosodimethylamine (NDMA) removal and Pharmaceuticals and Personal Care Products (PPCPs) appear on the regulatory horizon. Many times, advanced treatment requires combinations of different products in the treatment process.

  3. 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.

  4. Challenges For Water Utilities Spur Technology Upgrades
    10/11/2013

    Lee Odell, Water Treatment Global Technology Lead at CH2M HILL, discusses some of the current challenges that water utilities are facing and how CH2M HILL is well-poised to address them.

  5. 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.

  6. A 'Banner Year' For Ballasted Treatment
    10/14/2015

    It may not be mentioned as Ryan Seacrest begins the countdown on New Year’s Eve, but a few treatment plants scattered across the country may recall 2015 as the year of ballasted treatment.

  7. 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.

  8. Ozonia M and FiltraFast Provide New Options For Treatment Facilities
    11/20/2017

    If you don’t need the performance of an ultrafiltration membrane but also want to avoid the large footprint of a conventional media filter, you might want to consider FiltraFast extreme rate compressible media filters. As Ryan Hess, Director of Advanced Separation with SUEZ Water Technologies suggests in this Water Talk interview, “They provide roughly ten times the hydraulic loading rate of conventional media filters.”

  9. 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?

  10. Experience Pays Off For Gas Injection
    7/10/2017

    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.
