1. Product Overview Feiran EP’s Rotary Drum Fine Screen is a high-precision, self-cleaning filtration system designed for the most demanding solid-liquid separation tasks. Utilizing a rotating drum with precision wedge wire or perforated media, it effectively captures fine suspended solids from municipal and industrial wastewater. This unit serves as the ultimate protection layer, preventing downstream equipment fouling and ensuring the long-term stability of biological treatment processes.
2. Why Choose Feiran EP? Superior Capture Rate: The continuous rotating drum ensures a fresh screening surface at all times, achieving up to 95% solids removal efficiency for particles as small as 0.5mm. Integrated Self-Cleaning: Features dual-zone internal and external high-pressure spray bars that eliminate blinding, even when handling high-grease or fibrous materials. German Engineering Standards: Built entirely from SUS304/316L stainless steel and compliant with German DIN 19569 standards for maximum corrosion resistance and structural integrity. Low Operational Cost: The low-speed drive system and optimized washing cycle minimize energy and water consumption, reducing your total OPEX by up to 40%.

Q1: What is the advantage of Wedge Wire over Perforated Plate for drum screens?
Answer: Wedge wire (V-shape) profiles provide a two-point contact, which significantly reduces the risk of particles getting wedged in the slots. This makes it superior for applications with high concentrations of fibers or grease, as it is much easier to backwash and clean compared to standard mesh.
Q2: How does the internal washing system handle high-grease industrial wastewater?
Answer: Our system features a dual-zone high-pressure spray bar system (Internal + External). This ensures that fat, oil, and grease (FOG) are stripped from the drum surface continuously. For extreme cases, we can integrate a hot water wash system to maintain optimal screening efficiency.
Q3: Is the Rotary Drum Fine Screen suitable for outdoor installation in cold climates?
Answer: Yes. Feiran EP provides an optional fully enclosed stainless steel housing and localized heating elements for the spray bars and discharge chutes. This prevents freezing and ensures 24/7 operation even in sub-zero temperatures, typical for projects in Northern Europe or Central Asia.
