  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. Microbial Contamination Monitoring For Water Distribution Systems

    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.

    11/13/2014

    There are a number of regulations in drinking water centered around emerging contaminants. Hexavalent chromium is one that you’ll see on the national marketplace.

  5. 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?

  6. The Microbes Have Us Outnumbered 20 To 1: Should We Be Worried?
    7/12/2018

    A lot has changed over the past 15 years. Back in the early 2000s, many utilities weren’t interested in understanding what was in their water beyond the contaminant and disinfection byproduct levels they were regulated to comply with. But as Pat Whalen, President and CEO of LuminUltra, explains in this ACE 2018 Water Talk interview, a steady stream of ongoing education and the modern data storage and analytics that cloud computing provides, has developed some rabid fans eager to explore the microbiology of their water systems.

  7. 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.”

  8. 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.
