‌Rotary Drum Screen in Wastewater Treatment‌

Rotary Drum Screen OA1 Micro Strainer is one of the complete equipment products for water supply and drainage pretreatment.This equipment is widely used in sewage treatment projects such as urban sewage, industrial water, food processing industry, and paper industry. Cleaning, reliable and effective mechanical solid-liquid separation.
Rotary Drum Screen‌ is a critical mechanical screening device used in wastewater treatment to remove coarse and fine solids from influent streams. Designed as a rotating cylindrical drum with perforated or mesh panels, it efficiently separates debris, algae, and suspended particles through physical filtration‌

‌Rotary Drum Screen Technical Advantages


‌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.


‌Rotary Drum Screen Structure Principle

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.
