Hollow Fiber MBR Membrane Modules 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.

Engineering review
MBR Module Selection
Module quantity and total membrane area should be selected from the design flow, wastewater type, MLSS, operating flux, temperature, tank dimensions, pretreatment, aeration and target permeate capacity. The supplier can configure different element quantities and total membrane areas for the project, but no fixed m³/day capacity table is published until the capacity unit and design basis are confirmed.
Actual design flux and operating conditions must be confirmed against wastewater characteristics, temperature, MLSS, pretreatment and fouling tendency. For preliminary calculations, review the MBR membrane selection guide, membrane area framework and MBR flux and sizing guide.
Preliminary selection
Send the system basis
Send us your wastewater type, design flow, tank dimensions and existing membrane information for preliminary MBR module selection.
- Average and peak design flow
- Wastewater type and pretreatment
- MLSS and operating temperature
- Tank dimensions and available aeration
- Existing membrane model, drawings or photos

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.
