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 plants35.
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 efficiency26.
Durability: Constructed from corrosion-resistant materials like stainless steel (SS304/316), it withstands harsh environments in sewage bar screen and bar screen wastewater treatment applications14.
Compact Design: Suitable for space-constrained facilities, including bar screen water treatment plants and paper mill wastewater systems46.
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 materials36.
Compatible with bar screening processes, ensuring seamless integration into existing wastewater treatment workflows57.
The Rotary Drum Screen is installed at an angle of 35 degrees in a channel or a tank. Sewage flows into the basket drum, scum and suspended matters are intercepted accordingly.
When the water level before and after the grid reaches a determined difference in level, the waste scraping arm, fixed on the central axis, starts to rotate for cleaning.
The scraper brushes penetrates into the grid orifices, thoroughly clean the basket, removes the waste and transfer it via a screw conveyor to discharge it into a bin. The brushes are automatically cleaned during the drum rotation.
