,Anti corrosion Peripheral Drive Sludge Scraper
The Peripheral Drive Sludge Scraper is a continuous sludge and scum removal system designed for large circular sedimentation tanks. Driven from the periphery around a central column, the scraper arms rotate slowly to collect sludge from the bottom and skim scum from the surface. This system offers reliable performance, low maintenance requirements, and is widely used in both municipal and industrial wastewater treatment applications.
The scraper system consists of a working bridge, central column, drive unit, scraper arms, and scum removal system. The drive motor and gearbox rotate the arms around the tank center, with bottom scrapers pushing settled sludge to the central hopper while surface skimmers move scum to the scum trough. Sludge is discharged through a pipe and scum is removed by overflow or pumping, ensuring continuous sedimentation and automatic sludge removal.

- Scraper Arm & Blade: Push sludge to the central hopper
- Scum Scraper: Collects and directs surface scum
- Sludge Hopper & Pipe: Concentrated sludge discharge outlet
- Control System: PLC-based control with torque monitoring and protection
- Simple structure and smooth operation
- Optional dual-drive configuration for large tanks
- Automatic torque protection against overload
- Corrosion-resistant materials suitable for various water conditions
- Compatible with pumping or sludge discharge systems for full automation
- Primary and secondary clarifiers in municipal wastewater plants
- Industrial wastewater sedimentation tanks
- Clarification tanks in water purification plants
- Sedimentation systems in power, chemical, and cooling water facilities
- Anti-corrosion coating or stainless steel structure
- Automatic control with PLC
- Scum skimming device
