Automated Operation: Integrated with automatic bar screen mechanisms, it minimizes manual intervention by self-cleaning retained debris, making it ideal for high-flow municipal and industrial wastewater treatment plants.
Multi-Stage Screening: Combines coarse screen (for large debris) and rotary fine screen (for particles down to 0.5mm) in a single system, enhancing pretreatment efficiency.
Durability: Constructed from corrosion-resistant materials like stainless steel (SS304/316), it withstands harsh environments in sewage bar screen and bar screen wastewater treatment applications.
Compact Design: Suitable for space-constrained facilities, including bar screen water treatment plants and paper mill wastewater systems.
Cost-Effective: Reduces downstream equipment wear (e.g., pumps) and lowers maintenance costs, with modular designs allowing customization for specific mechanical bar screen design requirements15.
Advantages Over Alternatives:
Outperforms static band screens and mechanical fine screens in handling high solids loads and sticky materials.
Compatible with bar screening processes, ensuring seamless integration into existing wastewater treatment workflows.
The Rotary Drum Screen system is installed at a 35° angle as part of its mechanical bar screen design. Wastewater flows into the drum filter screen (or rotary drum screen wastewater unit) through the front-end opening, where coarse screen mechanisms—such as wedge-shaped grids or circular meshes—intercept scum, sediment, and suspended solids. The captured debris forms a "carpet effect" on the screen surface, enhancing filtration efficiency in bar screen wastewater treatment processes. When the water level differential across the mechanical screen wastewater unit reaches a threshold, the automatic bar screen wastewater treatment system activates. The Rotary Drum Screen rotates, lifting intercepted waste upward, while integrated mechanical fine screen components (e.g., scraper brushes and washing rods) discharge debris into a central hopper. A screw conveyor within the chute then compacts and dewaters the waste, aligning with bar screen water treatment standards for odor-free disposal.
