Wastewater Sedimentation Tank Sludge Scraper for Reliable Bottom Sludge Collection
Brief Description
The wastewater sedimentation tank sludge scraper is designed to collect and remove settled solids from treatment tanks. Its chain-driven scraper flights transport sludge toward the discharge area, helping improve sludge collection efficiency in municipal and industrial wastewater treatment systems.
Product Overview
The wastewater sedimentation tank sludge scraper is a mechanical system designed for removing settled solids during water and wastewater treatment.
As suspended solids settle at the bottom of a sedimentation tank, the chain-driven scraper flights continuously move the accumulated sludge toward a designated collection point. A reduction gearbox powers the circulating chains, providing a consistent scraping movement along the tank bottom.
The system features a simple mechanical arrangement, lightweight scraper components, and an above-tank drive installation. These design characteristics support convenient maintenance and low-energy operation.
Depending on the equipment configuration, the scraper can also assist with surface scum collection, providing additional solids removal functionality for compatible treatment tanks.
Working Principle
During operation, the reduction gearbox drives the chain mechanism, which carries the scraper flights along a continuous circulation path.
The scraper flights move along the tank bottom, pushing settled sludge toward the sludge collection zone. The sludge is subsequently removed through the designated discharge channel or sludge pumping system.
Where the equipment includes a compatible surface collection arrangement, floating scum and debris can also be directed toward the designated collection point near the tank outlet.
By continuously removing settled solids, the system helps support stable sedimentation and the overall operation of the wastewater treatment process.
