Description
OPERATING MODE
The Aqualitec Scraper Bridge is installed on circular clarifiers and settling tanks used for primary and secondary treatment applications. Wastewater enters through a central feed column where a center well diffuser promotes uniform flow distribution throughout the basin. As the bridge rotates, bottom scraper blades continuously push settled sludge toward the central sludge hopper for removal. Simultaneously, surface skimmers collect floating scum and direct it toward the scum box for discharge.
The clarified effluent flows radially toward the perimeter overflow weir, ensuring stable clarification performance and efficient solids separation.
- Why It Wins
Features & Benefits
Heavy-Duty Bridge Construction
The bridge structure is manufactured from hot-dip galvanized steel as standard, with stainless steel or aluminum construction available for demanding applications.
Efficient Sludge Collection
Bottom scraper assemblies continuously convey settled sludge toward the central hopper, ensuring reliable sludge removal and preventing solids accumulation.
Integrated Scum Removal
A dedicated surface skimmer system efficiently captures floating materials and transports them to the scum box for disposal.
Easy On-Site Adjustment
Scraper blades and skimmer components are designed for quick adjustment and simplified installation, reducing commissioning and maintenance time.
Reliable Center Pivot Drive
The rotating bridge is supported by a central pivot and gear drive assembly, ensuring smooth operation and dependable long-term performance.
