Wastewater Case Studies and Whitepapers

  1. The Benefits Of Adaptive Control Systems 2/21/2019

    In municipal and industrial wastewater treatment, there has been a shift from manual to automatic process control in order to increase efficiency and improve effluent quality.

  2. Tapping Into Big Savings With More Accurate Polymer Measurement 5/4/2021

    Polymers, especially flocculants and other thickeners, can be a major headache for drinking water and wastewater treatment plant managers. Power costs aside, buying polymer often represents the biggest expense of the treatment train. Not only are polymers pricey, but their high level of viscosity also presents a challenge to reliable measurement in varying conditions and at different levels of demand.

  3. Choosing The Right Water Disinfection 7/15/2019

    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. Answering Aeration's Big Dilemma — Repair Or Replace? 1/25/2019

    In wastewater treatment plants (WWTPs), repair vs. replace considerations are an ongoing dilemma. How much money is it sensible to spend repairing an older piece of equipment vs. upgrading to the best overall replacement option for current operating conditions? Even if the underlying hope is for a quick and easy repair, the answers are not always cut-and-dried. Before making the default decision to repair, evaluate key points that can pay dividends both immediately and over the long run.  

  5. Carbon Dioxide For pH Control Of Landfill Leachate 6/16/2016

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

  6. How To Avoid System Downtime When Installing Flow Meters 7/11/2018

    Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.

  7. Old City, New Ideas: Peracetic Acid In Wastewater Disinfection At St. Augustine 2/9/2016

    Wastewater treatment plants are required to disinfect effluent prior to discharge in order to destroy any pathogenic organisms present and minimize public health concerns.

  8. DELUMPER® LP Crusher Improves Cocoa Butter Processing 11/29/2020

    Chef Rubber, based in Las Vegas, Nevada, is a manufacturer and distributor of specialty supplies for chefs and well-known confectioners. The products include silicones, molds, colorants and colored cocoa butter. These unique tools are widely used by artisan chefs to create edible works of art for special events, competitions and other artistic applications.

  9. Premiere At The Goldsteig Cheese Dairy 2/5/2016

    A Kaeser EBS series screw blower is making wastewater treatment considerably more efficient and effective at the Goldsteig dairy factory in Cham in the Upper Palatinate region in Germany.

  10. Brewery Reuses Water For Factory Wash-Down 11/11/2013

    Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.
