Submersible mixers cut Italy wastewater treatment plant energy by 65 percent

RYE BROOK, NY, March 6, 2014 -- A wastewater treatment plant in Italy has reduced its energy consumption by 65 percent by employing advanced submersible mixers.

Xylem Inc. replaced the existing mixers with its new, mid-size energy-efficient Flygt 4530 submersible mixers, which feature a robust, high-efficiency propeller specifically designed for biological wastewater treatment applications.

The savings were realized as a result of a comparison study conducted by Comopedur, which operates the plant. Due to the significant energy and cost savings resulting from the installation, Comodepur ordered an additional three Flygt 4530 mixers to replace mixers in another equalization tank.

Luigi Cece, director of the Comodepur plant, said, "The new Flygt mixers have significantly reduced annual operating costs at the plant and have paid for themselves within just 13 months."

Located in the Lake Como region of northern Italy, the Comopedur plant treats 16 million cubic meters of wastewater annually, serving a population of approximately 200,000. Treated water from the plant is discharged into Lake Como. The plant's size and location in a heavily-populated area underscore the importance of reliability and consistency in its wastewater treatment process.
