Product Description
Heavy-Duty Mechanical Bar Screen 5000mm Ultra-Wide Channel High-Flow Sewage Screening Station Municipal Grade
The Heavy-Duty Ultra-Wide Channel Mechanical Bar Screen is engineered for large-scale municipal wastewater treatment plants, combined sewer overflow facilities, and major stormwater pumping stations where channel widths reach up to 5000 mm and influent flow rates exceed 100,000 cubic meters per day. This industrial-grade screening solution features a robust dual-drive chain rake system with synchronized motors on both sides of the channel, ensuring balanced load distribution and reliable debris removal even when handling irregularly shaped, heavy solid waste such as construction debris, large branches, plastic containers, and coarse sediment that frequently enter municipal collection systems during storm events.
The frame structure is fabricated from heavy-section hot-dip galvanized carbon steel with reinforced cross-bracing members that withstand the substantial hydraulic forces present in deep-channel installations. Each side frame incorporates precision-machined guide rail tracks with replaceable UHMWPE wear strips that minimize friction during rake travel while providing decades of maintenance-free service. The bar rack assembly consists of individual trapezoidal-cross-section bars spaced from 10 mm to 80 mm, each mechanically locked into the support frame to allow individual replacement without dismantling the entire screen. This modular bar design dramatically reduces maintenance downtime and lifecycle cost compared to fully welded bar racks that require complete replacement when a single bar is damaged.
Key Features
- Massive Channel Capacity: Designed for channel widths from 2000 mm to 5000 mm with depths up to 12000 mm, handling peak flows exceeding 150,000 m³/day with minimal head loss.
- Dual-Drive Synchronized Rake System: Two independent motor-reducer units with electronic synchronization via PLC ensure perfectly balanced rake travel across the entire channel width, preventing skewing and jamming.
- Heavy-Duty Bar Rack Construction: Individually replaceable trapezoidal bars (10 mm – 80 mm spacing) mechanically locked into a hot-dip galvanized support frame with 80-micron minimum coating thickness.
- Overload Protection Redundancy: Each drive motor is equipped with independent torque limiters, current-sensing relays, and mechanical shear pins providing triple-layer protection against catastrophic damage from large debris.
- Automatic Debris Discharge Control: Programmable discharge cycle logic adjusts rake travel speed, dwell time at the discharge chute, and cleaning brush engagement based on real-time debris load monitoring.
- Integrated Conveyor Interface: Discharge chute geometry and control logic pre-configured for seamless integration with belt conveyors, screw compactors, or skip hoist systems for automated debris handling.

Applications
The Heavy-Duty Ultra-Wide Channel Bar Screen is purpose-built for the largest-scale screening applications in the water and wastewater industry. Primary deployment scenarios include the headworks of municipal wastewater treatment plants serving populations exceeding 500,000, combined sewer overflow screening facilities requiring high debris capture rates during wet-weather events, thermal and nuclear power plant cooling water intake structures where large-volume screening protects condenser tubes, and major river water diversion and flood control projects. The screen is also well-suited for industrial complexes such as steel mills, petrochemical refineries, and mining operations that generate high volumes of coarse, abrasive solid waste in their process water circuits.
Packaging & Quality Assurance
Due to its substantial dimensions and weight, each Heavy-Duty Bar Screen is partially disassembled into major sub-assemblies for safe transport. The frame sections, bar rack modules, drive units, and control panels are individually packed in custom-built steel-reinforced export crates with desiccant bags and humidity indicators. All machined surfaces are protected with rust-preventive oil and wrapped in VCI paper. A complete set of assembly drawings, torque specifications, and step-by-step installation instructions is included. Factory engineers are available for on-site supervision of assembly and commissioning. The standard warranty period is 24 months from shipment, reflecting the robust design margin engineered into every component.
