Dual-Purpose Rotary Drum Screen for Wastewater & Stormwater Filtration
The premium Rotary Drum Screen stands as a critical asset for modern water resource engineering. From municipal headworks preprocessing to large-scale urban stormwater management and rainwater harvesting networks across Europe and North America, this system reliably filters vast volumes of surface runoff. Operating via a low-speed rotating cylinder, it ensures minimal head loss while handling unpredictable, high-velocity peak flows common in flash storm events.
Key Engineering Advantages for Global Infrastructure
Engineered specifically to manage massive surge flows without bypass. The unique internal layout permits rapid fluid transmission through the wedge-wire drum basket, making it perfect for critical rainwater collection channels.
Stormwater runoff often carries aggressive road salts, chemical residues, and abrasive sand particles. Our use of heavy-gauge stainless steel prevents premature pitting, structural wear, and rusting in damp outdoor basins.
Equipped with smart sensor-controlled high-pressure spray bars. It continuously flushes out fibers, organic mud, or plastic wrap debris from the screen grid, guaranteeing 100% operational uptime during unmanned storm seasons.
Versatile Applications: From Factories to Smart Cities
Our heavy-duty industrial rotary screens are meticulously optimized for demanding performance in a variety of sectors:
- Urban Stormwater Management: Primary screening for retention ponds, rainwater harvesting tanks, and infiltration galleries.
- Wastewater Pretreatment: Highly accurate screening for municipal wastewater treatment plants and MBR membrane protection.
- Food & Agricultural Facilities: Extraction of organic waste fractions from wash-down waters in meat, fruit, and vegetable factories.
- Industrial Water Loops: Closed-loop recycling system screening for pulp and paper mills, textile plants, and plastic recycling lines.

Frequently Asked Questions (FAQ)
A1: Our drum screens are designed with dedicated internal emergency overflow bypasses. During unusual 50-year or 100-year storm surges, the overflow structure ensures water continuous transit, while the main mechanical body processes maximum design throughput without flooding the vault.
A2: For European and American rainwater reuse and soakaway structures, we typically recommend a slot size of 0.25mm to 0.50mm. This effectively blocks fine silt, organic residue, and moss, drastically extending the service life of your downstream geotextiles and modular storm cells.
A3: Yes. For outdoor infrastructure projects, we offer premium double-walled, insulated stainless steel cabinets rated at IP65 (NEMA 4X) equipped with integrated thermal heaters and ventilation sensors to withstand freezing climates.
A4: Thanks to the automated backwashing nozzles and internal brush assembly, day-to-day operation is completely hands-free. A quarterly visual inspection of the spray bar pressure and lubricating the drive motor bearings once a year is generally all that is needed.
