    The Microbes Have Us Outnumbered 20 To 1: Should We Be Worried?

    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.

  • Data Modeling Helps Detroit Avoid $500M CSO Infrastructure Investment
    Data Modeling Helps Detroit Avoid $500M CSO Infrastructure Investment

    Five years ago, the city of Detroit, MI, filed the largest municipal bankruptcy in U.S. history at an estimated $18 to 20B. At the time, there was a lot of speculation in the water market as to how the city would continue to serve its citizens with viable water and sanitary sewer services. Ultimately Detroit reached a deal with neighboring Oakland, Wayne, and Macomb counties to create the Great Lakes Water Authority (GLWA), a new regional water and sewer authority. Spring forward to today and despite Detroit’s population continuing to dwindle, it’s water and sewer provision under the GLWA has recovered significantly.

  • Blower System Integration For Wastewater Aeration Applications
    Blower System Integration For Wastewater Aeration Applications

    The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.
