Rotary Drum Screen OA9 Micro Strainer Fully Enclosed Bar Screens For Wastewater

OA9 Series Rotary Drum Screen System for Wastewater Treatment

Rotary Drum Screen OA9 Micro Strainer is one of the complete equipment products for water supply and drainage pretreatment. For small and medium flow sewage filtration.

The ‌Rotary Drum Screen‌ serves as a ‌mechanical screen wastewater‌ component for primary solids removal in ‌wastewater treatment screens‌, utilizing a rotating cylindrical mesh to filter particles ≥0.5mm‌. Its modular design supports integration with ‌automatic bar screen wastewater treatment‌ systems, enhancing debris interception in municipal sewage and industrial effluent‌. Applications span ‌garbage sorting rotary drum screen‌ setups for solid waste separation‌, as well as textile and paper industries, where it handles fibrous residues using corrosion-resistant stainless steel (SS304/316) construction‌.

OA9 Series Rotary Drum Screen Applications

OA9 Series‌ Rotary Drum Screen Technical Advantages

Low investment costs
Reliable self-cleaning with sturdy spirals and wear-resistant brushes
Fully enclosed, no odour overflow
Set filter residues to flush and dewater, reducing subsequent disposal costs of filter residues
Quick and easy installation,also suitable for project reconstruction
All stainless steel, long service life, no maintenance required
Optional configuration for outdoor installation (heating insulation style)

OA9 Series‌ Rotary Drum Screen Structure Principle

The ‌OA9 series rotary drum screen‌ is installed at a 35° inclined angle to optimize solid-liquid separation in wastewater flows‌. Sewage enters the ‌drum filter screen‌ through the end-face opening of the screening chamber, where ‌rotary fine screen‌ mechanisms intercept scum, sediments, and suspended solids‌. The captured waste is then lifted via a closed screw elevator, undergoing simultaneous mechanical dewatering and compaction before discharge.
