MBR Membrane Bioreactor System
Product Overview
The MBR (Membrane Bioreactor) combines biological treatment with membrane filtration to produce high-quality, reuse-grade effluent in a compact footprint.
Working Principle
Biological treatment degrades organic matter while immersed ultrafiltration or microfiltration membranes physically separate treated water from biomass, replacing conventional clarifiers and delivering very low suspended solids and turbidity.
Key Features
- Integrated biological treatment and membrane separation
- Reuse-grade, low-turbidity effluent
- Small footprint with high biomass concentration
- No secondary clarifier required
Advantages
- Excellent and consistent effluent quality
- Ideal where space is limited or water reuse is required
- Modular and expandable
Applications
Technical Specifications
Indicative typical ranges to guide planning. Exact parameters are engineered and confirmed for each project based on your flow rate, influent quality and target discharge standard.
| Parameter | Specification |
|---|---|
| Treatment capacity (m³/day) | 5 – 5,000 m³/day |
| Influent quality (BOD / COD / SS) | BOD 150–500 / COD 300–1,000 / SS 200–600 mg/L |
| Target effluent standard | BOD ≤5, COD ≤30, SS ≤1 mg/L, turbidity <1 NTU (direct reuse) |
| Process type | Biological + UF/MF membrane (hollow-fibre or flat-sheet) |
| Footprint / installation | Smallest footprint; high MLSS 8,000–12,000 mg/L |
| Power supply | ≈0.8–1.5 kWh/m³ (membrane aeration + CIP) |
| Material of construction | PVDF / PES membranes; SS / GRP / concrete tank |
| Operation mode | Continuous, automated with periodic CIP |

Frequently Asked Questions
Is MBR effluent suitable for reuse?
Yes. After disinfection it is typically suitable for irrigation, flushing or cooling.
Does MBR need a clarifier?
No. The membranes replace the secondary clarifier.
What maintenance do membranes need?
Periodic cleaning to manage fouling; intervals depend on feed water and operation.
