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.
Xylem’s Flygt low speed mixers are ideally suited for digester conditions, combining large diameters with slow speeds. This generates maximum thrust with minimum energy consumption.
Xylem’s Flygt 4460 delivers optimal biogas production in the most cost-effective manner, due to its large-diameter, duplex steel propellers and super-hydraulic design.
