Centrifuge for thickening sewage sludge
In sewage treatment plants, managing the fine biological sludge generated during the decomposition process is a constant challenge. This sludge, known as excess sludge, needs to be thickened before entering the digestion tower to ensure stable biological treatment and optimal gas yield.
Efficiently thicken sewage sludge with constant feed
The Flottweg OSE Decanter is a centrifuge specifically designed for thickening sewage sludge. It maximizes the performance of digestion towers by maintaining a constant dry matter content in the thickened sludge, thus enhancing the digestion process. This decanter uses centrifugal acceleration to separate solid from liquid, increasing the dry matter concentration from 0.5-1% to 6-8%. The innovative Simp Drive® concept allows automatic adjustment of differential speed, ensuring consistent performance even with varying feed conditions. The special scroll design, including a deep pond and steep cone, increases sedimentation volume, enabling higher output density of up to 20%. Additionally, the Flottweg Recuvane® system boosts energy efficiency by further reducing power consumption by 20%.
