Flat Sheet MBR Membrane Modules
PVDF flat sheet membrane elements and cassette configurations for biomass separation in municipal and industrial MBR wastewater systems.
Product overview
Plate-type PVDF membranes for submerged MBR separation
Flat sheet MBR membrane elements are arranged in cassettes and submerged in a membrane tank or zone. Permeate is withdrawn under negative pressure while the membrane retains suspended biomass.
The membrane module is one part of the MBR process. Screening, biological design, MLSS condition, aeration, operating flux, relaxation and cleaning determine whether the complete system can operate reliably.
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
Potential use after contaminant-specific pretreatment and biological-treatability review.
Replacement and retrofit
Preliminary compatibility screening using the existing model, element and cassette drawings, connections, tank and operating data.
Selection
What needs to be confirmed
- Existing brand, model and installed quantity
- Element and cassette dimensions with dimensional drawings
- Net membrane area per element and per cassette
- Permeate header size, position and connection standard
- Tank dimensions, water depth and available lifting clearance
- Average, peak and instantaneous design flow
- Wastewater type, temperature, MLSS and sludge condition
- Current flux, TMP, aeration, relaxation and cleaning history
- Required supply scope: elements, cassette, headers, aeration or accessories
Important
Use approved supplier data
Do not select a flat sheet MBR module from nominal area alone. Dimensions, header position, cassette spacing, aeration, hydraulic mode, cleaning limits and the biological operating conditions must be checked against an approved drawing and current datasheet.
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 manufacturing-partner data; confirm the current quotation datasheet. |
| Membrane construction | PVDF separation layer with PET support | Confirm membrane, support, frame and sealing materials for the selected configuration. |
| Nominal pore rating | 0.1 μm | Supplier reference value; actual separation depends on membrane integrity and system operation. |
| Reference membrane area | 0.8 / 1.0 / 1.5 m² per element | Corresponding to the YF-FS-80, YF-FS-100 and YF-FS-150 reference sizes. |
| Reference element dimensions | 1000 × 490 × 7 / 1160 × 518 × 7 / 1750 × 490 × 7 mm | Final replacement requires an approved drawing, tolerances and connection review. |
| Filtration mode | Submerged negative-pressure suction | Permeate cycle, relaxation and aeration sequence remain project-specific. |
| Design flux | Confirm for the wastewater and operating temperature | Do not convert clean-water or initial supplier test output into a guaranteed design flux. |
| Module configuration | Element count and cassette arrangement confirmed per project | Tank, lifting, header and air-scouring interfaces require approved drawings. |
| Cleaning limits | Confirmed for the selected product and project | Chemical, concentration, temperature, contact time and frequency must be approved before operation. |
Reference sizes
YF flat sheet MBR elements for preliminary comparison
These reference values help screen a new or replacement inquiry. They do not replace the current datasheet, approved drawing or project flux review.
| YF model | Reference 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 |

Application boundary
When a flat sheet MBR module may—or may not—fit
Flat sheet modules may suit projects that value plate-based access, defined cassette layouts and submerged biomass separation. The configuration should be evaluated with the tank, aeration and operating strategy.
They should not be selected where the wastewater is not biologically treatable, where oils or chemicals exceed approved limits, where screening is inadequate, or where an existing cassette cannot accept the proposed dimensions and connections.

Common selection questions
Is PVDF flat sheet MBR suitable for every wastewater?
No. Biological treatability, screening, oils, chemicals, temperature, sludge condition and approved product limits must be reviewed.
Can a YF element replace another flat sheet MBR brand directly?
Only after dimensional, hydraulic, connection, cassette, aeration and operating compatibility are confirmed in writing.
How should design flux be selected?
Use representative wastewater, temperature, MLSS, fouling risk, operating cycle and available supplier or pilot evidence. A catalogue test output is not a universal design flux.
What information is needed for a quotation?
Send the required quantity and destination plus the existing model or new-system flow, wastewater type, tank, MLSS, drawings, dimensions and connection requirements.
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.
