MBR Membrane Modules for Wastewater Treatment
Flat sheet and hollow fiber MBR membrane modules sourced with application review, replacement coordination and export support from qualified Chinese manufacturing partners.
Applications: Municipal wastewater · industrial wastewater · decentralized treatment · water reuse
Product overview
Biological treatment plus membrane solid-liquid separation
A membrane bioreactor combines biological wastewater treatment with membrane filtration. Microorganisms perform the biological conversion, while the membrane separates biomass and suspended solids from treated water.
The membrane itself does not independently perform all COD or nitrogen removal. Biological design, sludge condition, dissolved oxygen, temperature, nutrient balance and operating control remain essential.
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 wastewater
MBR after suitable equalization and pretreatment for the specific industrial contaminants.
Replacement supply
Review of existing model, dimensions, area, header and operating data for compatible sourcing.
Selection
What needs to be confirmed
- Influent and biologically treated water quality
- Design and peak flow
- MLSS and sludge characteristics
- Tank layout and available footprint
- Operating flux and recovery philosophy
- Aeration demand and energy implications
- Cleaning method and chemical limits
- Existing element/module dimensions for replacement
Important
Use approved supplier data
A membrane comparison must include the biological process, operating strategy and lifecycle maintenance—not just pore size or purchase price.
Technical parameters
Specifications to confirm before supply
| Parameter | Published value | Selection note |
|---|---|---|
| Reference family | YF-FS-80 / YF-FS-100 / YF-FS-150 | YiFu reference designations based on the supplied manufacturing-partner data; confirm the current quotation datasheet. |
| Configuration | Organic flat sheet MBR element | Submerged suction configuration for biological wastewater treatment systems. |
| Membrane construction | PVDF separation layer with PET support | Confirm component and frame materials for the selected size. |
| Nominal pore rating | 0.1 μm | Supplier reference value; retention and effluent depend on integrity and system operation. |
| Reference element area | 0.8 / 1.0 / 1.5 m² | Corresponding to the YF-FS-80, YF-FS-100 and YF-FS-150 reference family. |
| Reference element dimensions | 1000 × 490 × 7 / 1160 × 518 × 7 / 1750 × 490 × 7 mm | Verify drawing, tolerance, header and cassette compatibility before replacement. |
| Filtration mode | Submerged negative-pressure suction | Flux, relaxation and aeration sequence are application-specific. |
| Design and cleaning limits | Confirmed per project | Water quality, MLSS, temperature and cleaning procedure must be reviewed before supply. |
Configuration comparison
Flat sheet, hollow fiber and ceramic MBR options
| Factor | Organic flat sheet | Hollow fiber | Ceramic option |
|---|---|---|---|
| Packing density | Generally moderate | Often high | Depends on element and module geometry |
| Maintenance access | Flat surfaces and plate arrangement may aid inspection | Fiber bundle access and integrity strategy are important | Rigid plates may support direct inspection within module design |
| Cleaning | Within polymer and component limits | Backwash or relaxation may be available by design | Potentially robust chemical cleaning within approved limits |
| Fouling response | Depends on sludge, aeration and operation | Depends on bundle hydraulics, sludge and operation | Depends on surface, aeration, sludge and operation |
| Capital considerations | Established option for many MBR systems | High area density can support compact layouts | Potentially higher initial cost; lifecycle case must be application-specific |
| Replacement | Check plate/module dimensions and interfaces | Check potting, header, frame and connections | Check module and system compatibility |
YF reference family
Flat sheet element sizes for preliminary comparison
Reference sizes support early replacement screening. Final selection requires an approved drawing and current YF datasheet.
| YF model | Reference membrane area | Reference dimensions | Initial supplier test output* |
|---|---|---|---|
| YF-FS-80 | 0.8 m² | 1000 × 490 × 7 mm | 320–480 L/element/day |
| YF-FS-100 | 1.0 m² | 1160 × 518 × 7 mm | 400–600 L/element/day |
| YF-FS-150 | 1.5 m² | 1750 × 490 × 7 mm | 600–900 L/element/day |

Common selection questions
Does an MBR membrane remove nitrogen by itself?
No. Nitrogen removal depends primarily on the biological process configuration and operating conditions. The membrane retains suspended biomass.
Which is better: flat sheet or hollow fiber?
Neither is universally better. Tank layout, sludge condition, packing density, maintenance practice, aeration and lifecycle cost determine fit.
Can YiFu recommend a replacement model?
Yes, after reviewing the current model, drawings, dimensions, membrane area, connections and operating data. Send the existing membrane model with your inquiry.
Send your application for a preliminary review
Share water data, flow, treatment objective or an existing membrane model. YiFu will coordinate the next technical questions.
Engineering selection
Continue from product comparison to MBR sizing
These guides separate module choice, area calculation and flux definition so each engineering assumption can be reviewed.
Select an MBR module
Match wastewater, configuration, tank, aeration, cleaning and maintenance requirements.
Open the module selection guide →Calculate membrane area
Use net production, a stated flux basis, filtration time and availability requirements.
Open the area calculation guide →Define flux and sizing
Compare flux terms, TMP, temperature, MLSS, fouling and operating-cycle assumptions.

YiFu coordinates flat sheet, hollow fiber and replacement requirements, technical selection, datasheets, quotation, OEM feasibility and export support without claiming to own the membrane factory.
Real product references
Flat Sheet and Hollow Fiber MBR Modules
These manufacturing references show two common submerged MBR configurations. Final module selection still depends on wastewater, tank layout, membrane area, aeration and operating strategy.
Commercial selection path
Move from MBR configuration to a quotation basis
YiFu supports product sourcing and technical coordination after the biological duty, membrane configuration and supply boundary are defined.
Define the wastewater duty
Document source, average and peak flow, temperature, MLSS, pretreatment, effluent objective and operating constraints.
Review MBR wastewater treatment →Choose a module configuration
Compare flat sheet and hollow fiber modules against tank fit, aeration, cleaning, maintenance and approved product data.
Compare MBR configurations →Confirm the project context
Industrial wastewater and reuse projects require contaminant-specific pretreatment and a treatment train beyond the membrane module.
