Our FHG Coarse Bar Screen is a heavy-duty pre-treatment solution engineered to automatically and continuously intercept these contaminants. Designed for 24/7 operation in demanding environments, it ensures uninterrupted performance for municipal wastewater plants, drinking waterworks, hydropower stations, and industrial pump stations.
Adopting isometrically distributed toothed harrows, the screen operates non-stop to capture floating objects without manual intervention. This prevents massive rubbish accumulation at intake points and reduces unplanned downtime by up to 70% compared to conventional screens.
Precision-engineered tooth harrows conform to irregularly shaped debris, ensuring thorough capture of even the most challenging contaminants. This high separation efficiency effectively protects downstream pumps, turbines, and treatment equipment from abrasion and damage, extending their service life by 30% on average.
Each FHG unit arrives completely assembled and factory-tested, eliminating complex on-site assembly work. Installation time is cut by 60% compared to modular screens, allowing your project to go online faster and reduce construction labor costs.
[Product Structure Diagram Alt: FHG Coarse Bar Screen Internal Components Labeled Diagram]
The FHG Coarse Bar Screen is built with 7 durable, corrosion-resistant modules:
Heavy-duty rotational drive system
Reinforced steel rack
High-tensile traction chain
Submersible underwater guide wheel
Dual-layer auxiliary and main grid
Slag retaining plate
Automatic top discharge system
The electric drive system powers the traction chain to move the tooth harrows in a continuous vertical loop.
Harrows descend behind the main grid and are redirected to the front by the underwater guide wheel at the channel bottom.
As harrows move upward, they seize all floating debris intercepted by the grid and lift it vertically to the top discharge section.
Debris is automatically scraped off the harrows and discharged onto a conveyor belt or garbage truck for off-site disposal.

Intercepts large floating debris to protect pumps, aeration systems, and secondary treatment equipment, reducing annual maintenance costs by up to $50,000 per plant.
Removes branches, leaves, and plastic waste from raw water intakes, ensuring the safety and efficiency of subsequent filtration and disinfection processes.
Prevents debris from damaging turbine blades and intake structures, minimizing power generation interruptions and extending turbine lifespan.
Protects water transfer pumps from clogging and mechanical damage, ensuring reliable water supply and drainage for residential, commercial, and industrial areas.
Suitable for food processing, paper manufacturing, textile, and mining industries, where large floating contaminants are present in effluent.
Our standard FHG series supports channel widths from 700mm to 2900mm. For channels wider than 2900mm, we can design custom multi-unit configurations to meet your flow requirements.
Yes, it is specifically engineered for 24-hour continuous or intermittent operation, making it ideal for high-flow wastewater treatment plants and waterworks that cannot afford downtime.
We offer stainless steel 304 for mild corrosive environments and stainless steel 316 for highly corrosive industrial wastewater applications. All components can be customized to your specific corrosion resistance needs.
Thanks to its fully pre-assembled design, installation of a standard FHG unit takes 1–2 days with a small crew. Our technical team can provide on-site guidance to ensure a smooth installation process.
