See how Xylem’s Flygt 4460 biogas mixer reduced mixing time and lowered maintenance at an ISB biogas plant in Dessau, Sachsen-Anhalt, Germany.
To increase mixing efficiency, an ISB biogas plant replaced a plastic propeller with a new Xylem stainless steel propeller. The new steel propeller provides much more thrust and improves energy efficiency. This has reduced mixing time by 25-30%, leading to significant cost savings.
In addition, the design of the new propeller, which has a spherical hub without edges, prevents solids from getting stuck. This has reduced the maintenance and servicing of the mixer.
