Product Overview
Our Rotary Drum Micro-screen is a premium high-efficiency self-cleaning filtration system, dedicated to removing fine suspended solids, fibers and particulate matter for tertiary wastewater treatment, water reuse and industrial process uses. Driven by a continuously rotating drum equipped with fine micro-screen panels, it yields stable, high-quality filtrate with minimal operator input, making it the optimal selection for attaining stringent effluent quality norms.
Working Principle
Water flows into the open end of the horizontally mounted drum and distributes internally, moving outward through fine screen panels (10–100 micron mesh or wedge wire) under low hydraulic head for gravity filtration, while solids are retained on the inner surface. Slow drum rotation lifts the captured solids out of the water, and high-pressure spray nozzles using clean filtrate discharge the solids into an internal collection trough at the apex. Clarified filtrate is collected in the outer effluent chamber, and the rinsed solids are conveyed for disposal.

Key Design & Performance Features
1. Simple structure with smooth operation, easy maintenance, and long service life.
2. High-capacity, efficient filtration, achieving over 80% recovery rate for fine suspended solids in wastewater.
3. Compact footprint, cost-effective operation, low-speed running with automatic protection, and easy installation.
4. Fully automated and continuous operation requiring no dedicated personnel; capable of discharging filter cake with a solids concentration exceeding 12%.
5. Can serve as an alternative to coarse filtration equipment such as mechanical bar screens.
Applications
Suitable for solid-liquid separation in diverse industrial wastewater systems, the micro-screen can remove fine particles larger than approximately 0.25 mm. It is widely used as pretreatment equipment for papermaking, tanning, slaughterhouse, brewing, printing and dyeing, textile and chemical wastewater. It performs exceptionally well in papermaking white water treatment for closed-loop recycling.
