The Rotary Drum Screen from Qingdao Linzhen Environment Project Co., Ltd. is a high-performance mechanical screening solution designed for the pretreatment stage of municipal and industrial wastewater treatment systems. It efficiently removes suspended solids, fibers, plastics, food residues, hair, leaves, and other coarse and fine particles before wastewater enters downstream treatment processes.
Featuring a continuous self-cleaning structure, precision stainless steel screen mesh, and automatic operation system, the Linzhen Rotary Drum Screen improves wastewater pretreatment efficiency, protects biological treatment equipment, reduces maintenance requirements, and lowers overall operating costs.
As a professional manufacturer of wastewater treatment equipment, integrated sewage treatment systems, industrial wastewater treatment solutions, and sludge treatment equipment, Qingdao Linzhen Environment Project Co., Ltd. provides customized rotary drum screening solutions for municipal projects, EPC contractors, environmental engineering companies, and industrial wastewater treatment facilities worldwide.
A Rotary Drum Screen is a highly efficient mechanical screening device designed for the preliminary treatment stage of municipal and industrial wastewater treatment plants. It removes suspended solids, fibers, plastics, food residues, leaves, hair, and other coarse and fine debris before wastewater enters downstream treatment processes.
Compared with traditional bar screens, a Rotary Drum Fine Screen provides continuous automatic operation, finer filtration accuracy, lower maintenance requirements, and higher screening efficiency. By reducing the solid load entering biological treatment systems, it protects downstream equipment, improves treatment performance, and lowers operating costs.
Manufactured from corrosion-resistant 304 or 316L stainless steel, the rotary drum screen is suitable for long-term operation in demanding wastewater environments. It can be installed as a standalone screening unit or integrated into complete wastewater treatment systems, including MBR, MBBR, SBR, DAF, Lamella Clarifier, and sludge dewatering processes.
The Rotary Drum Screen operates through a simple yet highly effective filtration process.
Wastewater flows into the interior of the rotating drum, where water passes through precisely machined screen openings while solid particles remain on the screen surface. As the drum slowly rotates, collected debris is lifted upward and continuously removed by an external spray cleaning system and scraper mechanism.
The cleaned screenings are discharged into a collection bin or conveyor for easy disposal, while the filtered wastewater flows to the next treatment stage.
This continuous self-cleaning design prevents clogging, maintains stable hydraulic capacity, and minimizes manual cleaning requirements.
Modern wastewater treatment plants require reliable screening equipment that can operate continuously with minimal maintenance. A Rotary Drum Screen offers several advantages over conventional static or manual screening systems.
High Screening Efficiency
The cylindrical drum provides a large filtration area within a compact footprint, allowing higher flow capacity while maintaining excellent solid removal efficiency.
Continuous Automatic Cleaning
An integrated spray washing system continuously cleans the screen surface, preventing blockages and ensuring stable long-term performance.
Compact Design
The enclosed drum structure requires significantly less installation space than traditional screening equipment, making it ideal for new plants and retrofit projects.
Reduced Maintenance Costs
Automatic operation greatly reduces labor requirements, while the simple mechanical structure minimizes maintenance and replacement expenses.
Corrosion Resistance
Constructed from high-quality stainless steel, the equipment offers excellent resistance to corrosion, chemicals, and harsh wastewater environments.
Reliable Continuous Operation
The slow drum rotation reduces wear on mechanical components, extending service life while maintaining stable performance 24 hours a day.
