Key Features & Advantages
1. Durable Stainless Steel Construction
The entire screening assembly, including the bar rack, rakes, and chain, is fabricated from high-grade stainless steel (304/316). This provides superior resistance to corrosion, abrasion, and harsh wastewater environments, ensuring long-term structural integrity and significantly reducing maintenance costs associated with rust and degradation.
2. Efficient Fine Screening Performance
With narrow, precisely spaced fine screen bars, the unit achieves high removal efficiency for solids as small as 3-6 mm. The inclined bar screen design optimizes the screening surface area and flow dynamics, enhancing debris capture while minimizing head loss and preventing clogging.
3. Fully Automatic & Reliable Raking System
The screen is equipped with a heavy-duty, fully automatic mechanical raker. Driven by a reliable motor and gearbox, the rake continuously cleans the bar rack, lifting captured solids to a discharge hopper. This automatic bar screen cleaning system ensures uninterrupted operation and eliminates the need for manual cleaning.
4. Compact & Space-Efficient Design
The unit’s inclined fine bar screen configuration allows for a compact footprint, making it ideal for both new installations and retrofits in space-constrained pump stations or treatment plant channels. Its modular and packaged bar screen design simplifies transportation, installation, and integration into existing structures.
5. Low Maintenance & User-Friendly Operation
Designed for reliability, the system features a simple mechanical drive, self-lubricating bushings, and an easily accessible control panel. An integrated automatic overload protection system safeguards the mechanism from jams. Minimal routine maintenance is required, translating to low operational costs and high availability.
Application Scenarios
1. Municipal Wastewater Treatment Plant Headworks
Serves as the primary screening unit to protect pumps, grit chambers, and biological processes from damaging fine debris such as plastics, rags, and other inorganic solids in sewage influent.
2. Industrial Wastewater Pretreatment
Installed at the inlet of industrial facilities (food processing, paper mills, textiles) to remove fine particulates and process-specific solids before further treatment, preventing equipment fouling.
3. Pumping Stations & Lift Stations
Critical for protecting pumps from clogging and wear in municipal sewage or stormwater pumping stations, ensuring reliable and efficient pumping operations.
4. Water Intake Structures
Used in surface water intakes (rivers, lakes, reservoirs) for power plants or water treatment facilities to screen out fine aquatic debris, leaves, and other floating materials.
Operation & Maintenance Guide
Routine maintenance includes periodic visual inspection of bar spacings and rake teeth, checking and greasing the drive chain, and clearing the discharge hopper area. A complete operation and maintenance manual is provided with the unit.
