Polymers flocculant to the secondary sludge thickening
In the sewage plants, the large lobe falls when cleaning the wastewater Secondary sludge in the biological cleaning level with a solid content of approx. 6-10 g/l TS (MW 7 g/l ts).
The secondary sludge is after the addition of polymer flocculation agents in static thickeners (2 x 4, 500 m³) thickened to a solid content of 4.5 to 5.5 % TR. Additionally become 100m³/h secondary sludge in a decanter centrifuge thickened to approx. 7.0 % TR
For the storage of liquid flocculation agents, a product main tank (20 m³) and a product tank is (10 m³). The tanks are filled by tank vehicles via a filling connection in the outside area on the building of the main sludge pumping station.
