Flanged, closed-end cylinder
Review the screen diameter, length, flange connection and end closure around the tank outlet and maintenance access.
CUSTOM SCREEN ENQUIRY
MBBR Media Retention Screens
MBBR retention screens keep carrier media within a biological treatment zone while allowing water to pass. Start the enquiry with the carrier dimensions, tank and outlet drawing, design flow and allowable headloss. Screen geometry is reviewed for the specific reactor arrangement.
- Screen form
- Carrier retention screens
- Specification
- Drawing and process requirements reviewed for each enquiry
- Supply scope
- Carrier retention screen enquiry for a defined tank and process; complete biological treatment design is outside the screen component scope.
Price, minimum order quantity, sample arrangements, packing and lead time are confirmed in the quotation.
Configurations to discuss
Multiple-screen arrangement
Define the number, spacing and support of screen elements with the design flow, tank geometry and carrier movement.
Specification and drawing checklist
These are the inputs needed to assess the screen. Final dimensions, material, slot and tolerances follow the accepted quotation and approved drawing.
| Parameter | Specify with your enquiry |
|---|---|
| Carrier media | Manufacturer / type, smallest dimensions, shape and required retention criteria. |
| Process duty | Normal, peak and emergency flow with units, filling ratio and operating water level. |
| Screen opening | Slot opening and tolerance selected for the actual carrier geometry and retention requirement. |
| Geometry | Cylinder diameter, effective length, element count and the available tank envelope. |
| Connection | Outlet size, flange / mounting drawing, orientation and seal details. |
| Mechanical conditions | Aeration, carrier impact, differential pressure and required support arrangement. |
| Hydraulic requirement | Permitted headloss, fouling allowance and any cleaning / air-scour requirements. |
| Material & access | Required grade, water chemistry, service temperature and screen removal route. |
North American drawings: keep the drawing's original units. Identify inches or millimeters, flow in GPM or m³/h, and pressure difference in psi, bar or kPa. Mark the complete pipe thread or flange standard where relevant.
A wastewater fine-screen opening cannot be assumed to be a suitable MBBR carrier-retention slot. Retention must be assessed against the carrier geometry.

Agree the order requirements
Include quantity and destination together with the drawing revision. Specify any material traceability, inspection, packing, sample or delivery requirement.
The quotation defines the supply boundary, technical acceptance points and commercial terms.
Quality & documentation requirements →Questions about mbbr media retention screens
How is the slot opening selected?
Use the actual carrier size and shape, retention requirement and hydraulic duty. The selected slot and tolerance need project review; there is no universal MBBR slot size.
Can I order a screen using tank flow only?
Flow is necessary but insufficient. Send the carrier data, filling ratio, water levels, allowable headloss, tank drawing and cleaning or aeration conditions.
What support information matters?
Provide the support points, unsupported length, connection details and expected aeration or media-impact conditions so the assembly can be reviewed.
Is the installation photo your completed project?
No. It is a credited third-party configuration reference. The proposed screen geometry and supply scope for your enquiry are documented separately.
