Converting waste streams from agricultural and food production, as well as effluents from industrial and municipal wastewater treatment plants, into biogas is good for the environment, and when done efficiently, enhances bottom line.

Anaerobic digestion is a natural process, and relatively simple in concept. However, producing biogas efficiently requires effective pumping and mixing of often difficult substrates.

Xylem’s Flygt 4460 delivers this optimum biogas production in the most cost-effective manner through its large diameter duplex steel propellers and super hydraulic design.

Rugged Non-stop Performance

These duplex steel propellers operate effectively on the most challenging digester contents. Its spherical hub structure ensures a clog-free operation even with fibrous substrates. Moreover, its motors and heavy-duty gearboxes guarantee reliability and non-stop performance. 

High Efficiency in Biogas Media

Flygt 4460 run at low speeds for maximum thrust at minimum power consumption. It is especially made to perform in high yield stress and high viscosity liquids, providing effective mixing and low energy cost. 

Adjustable Positioning

Installed on the dedicated biogas installation equipment, with depth and angle adjustment, Flygt 4460 offers the most flexible configuration for the proper digester operation, to optimize biogas production and avoid process disturbances.

Service Satisfaction Guaranteed

With Xylem’s worldwide presence and its vast experience in biogas mixer installations all over the world, you can be assured of quick service turn-around times and spare part deliveries.
