High-Performance Inward-flow Perforated Plate Screen for Fine Wastewater Screening
Engineering Excellence: German DIN Standards & Technical Specifications
- Item 1:0% Bypass Rate. Perforated plates ensure all water passes through the filter media, eliminating debris bypass.
- Item 2:German DIN Standards. Built with heavy-duty SUS304/316L stainless steel for maximum corrosion resistance.
- Item 3: Low Maintenance. Continuous self-cleaning mechanism reduces operational downtime and labor costs.
The Industry Challenge: Traditional coarse screens often suffer from “debris bypass,” where hair and fibers escape through side gaps or carry-over at the top. These contaminants lead to downstream pump clogging and severe membrane fouling in MBR systems, increasing maintenance costs and operational downtime.
The Feiran EP Solution: Our Inward-flow Perforated Plate Screen features a “U-shaped” flow pattern and precision-sealed perforated panels. This design ensures that 100% of the wastewater passes through the filter media, achieving a 95% solids capture rate. It provides the ultimate defense for sensitive downstream equipment, dropping your system’s emergency repair costs by up to 50%.

| Solids Capture Rate | Up to 95% (Zero Bypass Design) |
| Compliance Standard | German DIN 19569 Standard |
| Cleaning Mechanism | Continuous High-Pressure Self-Cleaning |
Q1: How does the inward-flow design prevent debris bypass?
Unlike traditional front-entry screens, the inward-flow mechanism seals the perforated plates against the frame. This forces all water to enter from the center and exit through the sides, ensuring even the smallest fibers and hair are captured and removed by the high-pressure spray bar.
Q2: Q2: What is the lifespan of the perforated plates under harsh conditions?
Answer: Built with premium SUS304 or SUS316L (optional Duplex Steel) and engineered to German DIN 19569 standards, our plates are designed for a 20+ year lifespan. The continuous high-pressure backwash system prevents grit accumulation, significantly reducing wear and tear.
Q3: Can this screen be customized for existing deep concrete channels?
Answer: Yes. Feiran EP provides custom engineering for channel widths from 500mm to 3000mm and depths up to 10 meters. We provide full CAD drawings and technical support to ensure a seamless “drop-in” installation for both new builds and retrofitting projects.
