The fiberglass sludge sedimentation tanks of the Dortmund type are generally of a circular plan with a conical end and have a surge pipe with notched duct.
The sedimentation process starts with the entering of the sludge or sewage inside the surge pipe, then a slow process begins where the sludge deposits on the cone, while the rising of the water to the notched duct placed on the surface of the sedimentation tank allows a better filtering.
The walls of Dortmund sludge sedimentation tanks are very slanted to avoid the formation of sediments on the walls. In fact, the minimum inclination angle is 45°.
The diameters available for these sedimentation tanks are:
DN 4000, DN 3000, DN 2500, DN 2200, DN 2000, DN 1800, DN 1600, DN 1500, DN 1400, DN 1250, DN 1100, DN 950.
Sedimentation tank of 2500 mm in diameter with frame to support the surge pipe
Sedimentation tank with painted legs of 2200 mm in diameter
Sedimentation tank with painted legs of 2200 mm in diameter
Surge pipe supported by inner arms
