High-Performance Step-type Fine Screen for Municipal & Industrial Wastewater
Engineering Excellence: German DIN Standards & Technical Specifications
- Item 1: Zero Wash Water Required** relying purely on mechanical step-lifting motion, drastically reducing daily OPEX.
- Item 2: Fiber & Rag Immune Design** with alternating lamellae that inherently prevent tangling and surface blinding.
- Item 3: 20+ Years Lifespan** constructed from premium SUS304/316L stainless steel to German DIN 19569 standards.
1. Product Overview
Feiran EP’s Step-type Fine Screen is an advanced, self-cleaning filtration unit designed to lift and remove debris from wastewater channels step by step. Built entirely from premium SUS304/316L stainless steel, its unique movable and fixed lamellae design prevents the accumulation of hair, fibers, and rags. This ensures continuous, uninterrupted flow and protects downstream biological treatment units from physical damage.
2. The Industry Challenge & Solution
The Industry Challenge: Traditional fine screens often struggle with fibrous materials and long rags, which quickly wrap around rotating components and cause severe “blinding” (clogging). This leads to high water head loss, dangerous manual cleaning requirements, and frequent maintenance shutdowns.
The Feiran EP Solution: Our Step-type Fine Screen utilizes an alternating motion of fixed and movable stepped plates. This design inherently “lifts and peels” the debris mat upwards without relying on rotating brushes or high-pressure water. The result is a 100% self-cleaning, clog-free operation that eliminates brush replacement costs and reduces your total OPEX.

Why is the Step-type Screen better for highly fibrous wastewater?
Unlike drum or mesh screens, the Step-type screen has no rotating parts or chains in the submerged area where rags can tangle. The lifting motion of the movable lamellae simply peels the fiber mat off the fixed steps automatically, making it the most reliable choice for municipal sewage with high hair and rag content.
Does this screen require high-pressure backwash water?
No. One of the biggest ROI advantages of the Step-type Fine Screen is that it operates entirely on the mechanical lifting motion of the steps. This means ZERO backwash water consumption, saving massive amounts of clean water and electricity over its 20+ year lifespan.
Can it be retrofitted into our existing deep concrete channels?
Absolutely. Feiran EP custom-engineers the frame width and discharge height to match your existing civil works perfectly. We provide detailed CAD drawings to ensure a seamless “drop-in” installation with no channel modifications required.
