Rotary Bridge

Rotary Bridges are electromechanical systems designed and manufactured by Mojan for circular sedimentation tanks in water and wastewater treatment plants. These systems are used for the efficient separation of solid and liquid phases through sedimentation and flotation processes.

Sedimentation tanks maintain wastewater in a relatively quiescent condition to allow settleable and floatable solids to separate from the liquid phase. The separated solids are then collected and transferred for further treatment processes.

Mojan Rotary Bridges are designed for circular sedimentation tanks and include all required mechanical and electrical components for reliable operation.

Main Components:

• Bridge Structure
  • Main structural frame of the rotary bridge, designed to move across the sedimentation tank.
• Central Bearing Assembly
  • Provides the central rotating support for the bridge structure.
• Electric Motor and Gearbox
  • Provides the driving force required for continuous rotation of the bridge.
• Traveling Carriage
  • Supports movement of the bridge along the tank perimeter.
• Sludge Scraper System
  • Collects settled sludge from the bottom of the sedimentation tank and directs it toward the sludge collection area.
• Scum Removal System
  • Removes floating materials and surface scum from the tank.
• Control Panel
  • Provides system control and operation management.

Applications:

Rotary Bridges are mainly used in:

• Circular sedimentation tanks in wastewater treatment plants
• Solid-liquid separation processes
• Sludge collection and removal systems
• Primary and secondary clarification units

Key Features:

• Efficient separation of solid and liquid phases
• Low energy consumption
• Economical design and engineering
• Low maintenance requirements
• Easy installation and commissioning
• Long service life
