Overview of the cleaning methods
Surge flushing
Practical example I
Wastewater volume activated flushing system
Rotating elbow
Investigations revealed that extensive and partially solidified deposits with critical erosion shear stresses up to 14 N/m2 could be eliminated up to a channel length of approximately 300 m. Sedimentation of the mobilized deposits was prevented up to a length of 700 m.
These results were confirmed by an analysis of the surge wave in a large diameter sewer [Lützn96].
