  • Choosing The Right Water Disinfection
    Choosing The Right Water Disinfection

    In the mid-to-late 1800s, chlorine had been used sporadically to help control infection in hospitals and drinking water. Common water treatment did not start in the U.S. until the early twentieth century when increasing cases of waterborne illnesses prompted many large cities to begin large scale filtration of water supplies.

  • 4 Misconceptions Of AOP For Wastewater Treatment
    4 Misconceptions Of AOP For Wastewater Treatment

    Advanced oxidation is a rather complex wastewater treatment process. The general concept of how the process works can be difficult to grasp at first, and the number of possible oxidation methods can seem daunting. Therefore, you turn to the internet for information, and try to analyze together all the information you find using various online resources. However, everything doesn’t always fit right, and you come up with ideas that may not be quite true.

  • Combining Biosolids Waste Streams?  Not So Fast…
    Combining Biosolids Waste Streams? Not So Fast…

    The idea of combining two systems into one sounds like a common-sense solution to simplifying operations.  Wastewater treatment plant operators have been experimenting with this concept by combining waste activated sludge with primary and septage waste streams with the goal of lowering system complexity.  The reality of these efforts is proving, in many cases, to be problematic.

  • Sludge Thickeners: The Good, The Bad, And The Smelly
    Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

  • Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy
    Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

    Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

  • Sludge Sampling For Polymer Selection – Critical For Project Success
    Sludge Sampling For Polymer Selection – Critical For Project Success

    Polymers — the chemicals used in wastewater to thicken sludges and facilitate the removal of water — are critical to the operational efficiency of sludge-thickening equipment.  Unfortunately, it’s common practice at treatment facilities to order and install equipment before even considering what the ideal polymer might be for the sludge produced at the specific plant. This flawed process is time consuming, disruptive to plant operations, and can become very costly.
