Sludge Scraper System Function
- For peripheral operation,the bridge rotates.
- The bridge support bearing is assembled on top of the central column.
- The bridge is powered by a front wheel driven end-carriage running on top of the tank wall.
Sludge Scraper System Design Details
The first sedimentation tank is a circular radial-flow sedimentation tank which discharges sludge in the center. Water flows into it in the center and is then discharged through surrounding outlets. The sludge is discharged under a static water pressure from the center mud trough.
