Product Detail

Fiber bundle filter

I. Product Features

1. High filtration accuracy: Achieves 100% suspended solids removal. With properly coagulated natural water (20NTU influent), effluent turbidity maintains <2NTU.

2. Rapid filtration: Standard filtration velocity reaches 30m/h (3-5× conventional filters), with maximum capacity of 50m/h.

3. Large dirt-holding capacity: 5-10kg/m3 (2-4× conventional filters).

4. Adjustable parameters: Customizable filtration accuracy, dirt-holding capacity, and flow resistance.

5. Compact footprint: Occupies 1/3-1/2 space of conventional filters for equivalent output.

6. Low per-ton water cost: More economical than traditional systems.

7. Efficient backwashing: Consumes only 1-3% of cyclic water production, typically using raw water for upward flushing.

8. Extended service life: No filter element replacement required; contaminated elements are cleanable with ≥10-year lifespan.
