Rotary Drum Filter Manufacturer | High-Efficiency Wastewater Screening Equipment

Rotary Drum Filter for Industrial & Municipal Wastewater Treatment

Rotary Drum Filter is an efficient mechanical screening system designed for continuous solid-liquid separation in wastewater treatment applications. It removes suspended solids, fibers, plastics, food residues, and other debris before biological treatment. It helping reduce COD, BOD, and TSS while protecting downstream equipment.

As a professional Rotary Drum Filter manufacturer, we provide customized screening solutions for municipal wastewater plants and industrial wastewater treatment projects worldwide. Our equipment features high filtration efficiency, low energy consumption, automatic cleaning, and long service life.

Whether you are designing a new wastewater treatment plant or upgrading an existing system, our Rotary Drum Filter provides reliable pretreatment performance for a wide range of industries.

Why Choose Our Rotary Drum Filter?

• High Screening Efficiency: The wedge wire or perforated drum provides precise filtration with opening sizes ranging from 0.25 mm to 5 mm, ensuring excellent removal of suspended solids.
• Automatic Self-Cleaning: Integrated spray nozzles continuously clean the filter surface, preventing clogging and minimizing maintenance requirements.
• Low Energy Consumption: Driven by a high-efficiency geared motor, the drum rotates only when necessary, significantly reducing operational costs.
• Continuous Operation: Designed for 24/7 operation with stable performance and minimal operator intervention.
• Compact Design: The equipment requires limited installation space and can be easily integrated into existing wastewater treatment systems.
• Corrosion Resistant: Manufactured from SS304 or SS316 stainless steel, ensuring excellent resistance to corrosion and long service life even under harsh wastewater conditions.
• Customizable Design: Available in multiple capacities, drum diameters, screen sizes, and installation configurations to meet project-specific requirements.
