Kynar PVDF Jet Aerator For Improved Wear Resistance Kynar PVDF Jet Aerator For Improved Wear Resistance

Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles.  The inner nozzle is the liquid propulsion nozzle of the jet aerator and continuously sees high volumes of motive liquid flow at velocities ranging from 33-46 ft/s.  Traditionally, these inner jet nozzles were made from the same FRP material as the outer jet with the industry accepted corrosion/abrasion liner made up of C-Glass/Nexus and Silicon Carbide impregnated into the vinylester resin.  For many years this material had held up in most industrial and municipal bioprocesses with no adverse deterioration or wear.

  • Going Bold To Shine A Spotlight On Stormwater Pollution
    Going Bold To Shine A Spotlight On Stormwater Pollution

    Too many dog owners think their pets’ waste easily breaks down in nature and is helpful to plants, so they leave it on the ground. The truth is that dog poo and other pet waste is loaded with germs such as e. coli and giardia that make people sick as well as nutrients that can fuel problematic algae blooms.

  • Location, Location — The Key To Aeration
    Location, Location — The Key To Aeration

    As with any industrial process, the right tool for the job depends on the nature of the task at hand. In aerobic wastewater treatment, that optimal choice often comes down to a balance between the biological and financial demands of the application. Either way, here are several performance comparisons of how multiple aeration methods and locations stack up in industrial wastewater treatment applications.

  • 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.
