Chain Flight Sludge Scraper with Integrated Sludge and Scum Removal
Brief Description
The chain flight sludge scraper combines bottom sludge collection with surface scum removal in compatible sedimentation tank configurations. Its circulating chain and scraper flight system supports continuous operation, simplified mechanical design, and low energy consumption for municipal water treatment and wastewater treatment applications.
Product Overview
The chain flight sludge scraper is designed to remove settled sludge and collect floating scum in sedimentation tanks. Driven by a reduction gearbox, the circulating chains carry scraper flights along a continuous path to move sludge toward the designated discharge area.
The scraper mechanism can also assist in directing floating scum and debris toward the collection system near the tank outlet, depending on the equipment configuration. This combined function helps reduce the need for a separate scum removal machine in suitable applications.
Featuring lightweight non-metallic components and an above-tank drive arrangement, the system offers convenient access for maintenance and helps maintain reliable operation in water and wastewater treatment processes.
Working Principle
The chain flight sludge scraper is powered by a reduction gearbox that drives the circulating chains and scraper flights.
During operation, the flights move continuously along the tank bottom, pushing settled sludge toward the sludge collection area for discharge through the designated channel or pumping system.
At the water surface, the scraper mechanism can collect floating scum and debris and guide them toward a scum collection pipe or other designated collection arrangement near the tank outlet, where provided by the equipment design.
The removal of settled sludge and surface floating matter helps maintain the sedimentation process and supports subsequent water treatment operations.

Key Design & Performance Features
1. Combined Sludge and Scum Removal
Supports bottom sludge scraping and surface scum collection in compatible tank configurations, potentially reducing the need for separate scum removal equipment.
2. Continuous Chain Flight Operation
The circulating chain system allows the scraper flights to operate continuously along a fixed path without frequent directional changes.
3. Lightweight Non-Metallic Components
Non-metallic scraper components help reduce equipment weight and mechanical loading.
4. Simplified Drive and Control Arrangement
Continuous unidirectional movement eliminates the need for frequent reversing operations and simplifies the operating mechanism.
5. Convenient Above-Tank Installation
The drive unit is mounted on the platform above the tank, allowing easier access for inspection, electrical connections, and routine servicing.
6. Energy-Efficient Operation
The lightweight structure and continuous scraping arrangement help support low-energy operation.
Applications
1. Municipal wastewater treatment plants
2. Water supply and water treatment facilities
3. Sedimentation tanks requiring bottom sludge collection
4. Treatment tanks requiring both sludge and surface scum removal
5. Industrial wastewater treatment systems with compatible tank configurations
6. Sludge settling and separation processes
