Superior Screening Principle & Process
The heart of this Fine Screening Drum Screen lies in its internal feed design. Wastewater enters the rotating drum's interior, where the liquid permeates through the finely perforated screens or wedge wire panels. Solids are trapped on the inner surface and are elevated as the drum rotates. A strategically placed spray system cleans the screen, while a scraper mechanism ensures positive solids discharge, guaranteeing a consistent Continuous Flow process.
Robust Construction for Demanding Environments
Built for longevity and corrosion resistance, this Stainless Steel Drum Screen is constructed with high-grade stainless steel for all critical components, including the drum, screen panels, and the main frame . This ensures exceptional durability and reliable performance in harsh and corrosive wastewater environments, significantly reducing long-term maintenance costs.
Key Advantages for Tropical & Developing Regions
Uninterrupted Operation: The Continuous Flow Stainless Steel Drum Screen is engineered for non-stop, 24/7 operation, making it ideal for high-flow treatment plants where downtime is not an option.
Compact & Space-Saving: Its vertical design and large effective screening area within a small footprint make this Fine Screening Stainless Steel Drum Screen perfect for facilities with severe space constraints or for retrofitting into existing plants .
High Efficiency & Low Energy Use: The system captures fine particles with high efficiency, thanks to screen openings available from 0.25mm to 6mm . Its optimized hydraulic and mechanical design ensures low power consumption, a critical factor in regions with high energy costs .
Minimal Maintenance & Easy Operation: With no complex mechanisms and an integrated self-cleaning system, the Continuous Flow Fine Screening Drum Screen requires minimal operator intervention. This simplicity is a significant advantage in areas where specialized technical expertise may be limited.
Versatile Application Range
This highly adaptable Stainless Steel Drum Screen is proven effective across a wide spectrum of applications. It is ideally suited for:
Screening raw sewage in municipal wastewater treatment plants.
Industrial process water and wastewater treatment in food processing, chemical, paper, and textile industries.
Pretreatment for membrane bioreactors (MBRs) to protect downstream equipment.
