Digester mixing maintains homogeneity of the fluid, evenly distributes the bacteria, maintains uniform temperature conditions and prevents the formation of thermal and density layers to maximize biogas production. Conditions inside an anaerobic digester or fermenter are harsh. Flygt submersible mixers are rugged, built to withstand harsh environments and provide years of reliable service at the lowest possible life cycle costs.
Xylem’s Flygt low speed mixers are ideally suited for digester conditions, combining large diameters with slow speeds to generate maximum thrust with minimum energy consumption. With multiple models available, Xylem’s hydraulic engineers can tailor a system for the properties of the material (percent solids) and the size and shape of the tank, to ensure complete, effective and energy efficient mixing.
