WLW Rotary Outward-Flow Microfilter: Continuous mechanical filtration with inverted trapezoidal anti-clogging design, 30% lower slag moisture, and outward-flow microfilter technology for paper and brewing wastewater pre-treatment.
Product Overview
The WLW Rotary Outward-Flow Microfilter is a continuous, highly efficient mechanical filtration system designed for small to medium municipal and industrial wastewater treatment plants. This equipment specializes in wastewater pre-treatment and industrial screening processes, effectively removing fine suspended particles larger than 0.25mm in diameter. During operation, it eliminates 30% to 60% of organic and inorganic suspended solids, significantly reducing downstream treatment loads. Ideal for heavily polluted industries including papermaking, tanning, slaughtering, brewing, food processing, chemical fibers, and textiles.

Key Features & Benefits
Inverted Trapezoidal Anti-Clogging Design: Grid bars feature scientifically engineered inverted trapezoidal cross-sections that prevent debris jamming, ensuring continuous high flow rates and eliminating screen blockages.
Ultra-Low Slag Moisture Content: Processes impurities with 30%-50% lower moisture content than traditional inward-flow equipment, significantly reducing solid waste volume and subsequent disposal costs.
Variable Speed & Dual Cleaning System: AC variable-speed motor adjusts to actual influent flow rates, while specialized flushing and secondary internal flush systems thoroughly remove trace impurities for optimal cleaning performance.
Compact & Trench-Free Installation: All-stainless steel construction with compact footprint enables direct pipe connections and floor mounting with expansion bolts, eliminating civil trench excavation requirements.
Frequently Asked Questions
What size of impurities can this equipment effectively handle?
The system provides high-precision filtration, removing fine particles larger than 0.25mm in diameter while eliminating 30% to 60% of organic and inorganic suspended solids from wastewater.
What is the main advantage of an outward-flow microfilter over an inward-flow model?
The primary advantage is significantly drier discharged solid waste. Outward-flow technology reduces garbage moisture content by 30%-50% compared to legacy inward-flow systems, substantially decreasing solid waste volume and lowering disposal costs.
Do we need to damage our existing facility floor to dig trenches for installation?
No trench excavation is required. Installation is straightforward with direct pipe connections for both inlet and outlet, and the unit can be securely mounted on any flat surface using expansion bolts.
