304 Stainless Steel Center Drive Scraper for Circular Wastewater Treatment

This centrally-driven sludge scraper is specifically designed for radial flow (circular) sedimentation tanks with diameters up to 18 meters in water treatment plants and municipal sewage facilities. The system efficiently collects and removes settled sludge through a robust减速 drive mechanism and suspended scraper assembly. Sludge is guided toward a central collection hopper and discharged via hydrostatic pressure or pumping systems. Featuring a central inlet and sludge discharge with peripheral overflow weirs, the tank ensures uniform flow distribution and optimal settling conditions. The system includes an integrated skimmer for surface scum removal and is equipped with overload protection for reliable, automated operation.

Key Features:

• Constructed with corrosion-resistant 304 stainless steel for extended service life

• Central drive design with precision reduction gearing for consistent torque output

• Central feed and sludge discharge with peripheral water collection for balanced hydraulic flow

• Automated skimming system for efficient surface scum removal

• Integrated overload protection prevents damage during operation

• Suitable for tanks up to 18 meters in diameter

Typical Applications:

• Municipal wastewater treatment plants

• Drinking water treatment sedimentation basins

• Industrial wastewater circular clarifiers

• Water reuse and recycling facilities

Working Principle:
The scraper system rotates continuously, moving settled solids toward the central hopper while surface skimmers remove floating materials. The balanced hydraulic design maintains ideal settling conditions while the robust drive system ensures reliable operation with minimal maintenance requirements.
