Biomass separation in designed biological treatment systems.
YiFu Trading
Hollow Fiber MBR Membranes for Wastewater Treatment
High-packing-density membrane modules for biomass separation in suitable municipal and industrial MBR systems.
Product overview
Compact membrane area within fiber bundles
Hollow fiber MBR modules contain many small-bore membrane fibers connected to a permeate header. They can provide substantial membrane area within a compact tank footprint.
Fiber material, potting, support frame, aeration pattern, integrity management and cleaning procedure all affect practical performance.
Application fit
Typical roles and use cases
These are potential roles, not guaranteed performance claims. The complete process and verified product limits must be reviewed.
Industrial MBR
Use after contaminant-specific pretreatment and biological treatability review.
Module replacement
Compatibility assessment using current drawings, header details and operating conditions.
Selection
What needs to be confirmed
- Fiber material and direction of filtration
- Module area and packing density
- Header and permeate connection
- Frame dimensions and lifting method
- Aeration arrangement and airflow
- Backwash, relaxation and cleaning sequence
- Integrity testing and repair approach
Important
Use approved supplier data
A similar-looking module may not be hydraulically or mechanically interchangeable. Obtain approved compatibility confirmation.
Technical parameters
Specifications to confirm before supply
| Parameter | Published value | Selection note |
|---|---|---|
| Reference family | YF-HF-MF / YF-HF-UF | YiFu reference designations for reinforced PVDF hollow fiber modules. |
| Fiber material | Reinforced PVDF | Confirm potting, header and support-frame materials for the selected module. |
| Nominal pore rating | 0.1 μm MF / 0.03 μm UF | Choose the grade against separation objective and current datasheet. |
| Reference membrane area | MF: 5.7–31.3 m²; UF: 6–38.8 m² | Available area depends on module dimensions and configuration. |
| Filtration direction | Outside-in | Submerged suction operation. |
| Reference design flux | 10–30 LMH | Use application water quality, temperature and pilot data to establish project flux. |
| Reference TMP range | 10–40 kPa | Operating and alarm limits must be coordinated with controls and cleaning. |
| Reference operating envelope | 5–40°C; pH 2–11 | Confirm continuous-operation and chemical-cleaning limits separately. |

FAQ
Common selection questions
Can hollow fiber MBR membranes be backwashed?
Some designs support backwash and others use different operating cycles. Confirm the selected product and system design.
What causes fiber damage?
Potential causes include abrasion, fatigue, handling, excessive pressure, chemical exposure or foreign objects. The actual cause needs investigation.
What should I send for a replacement inquiry?
Send the current brand and model, module photos, drawings, dimensions, connections, installed quantity and operating conditions.
