Description
Containerized Membrane BioReactor For Waste Water Treatment
Technical information
MBR technology can meet various wastewater treatment applications that require high-quality wastewater to meet regulatory requirements or can be reused. The membrane ensures high quality and one-stop responsibility. The targets of MBR are biological oxygen demand (BOD), total suspended solids (TSS), bacteria, total coliforms, ammonia, nitrogen and phosphorus.
MBR also eliminates many drugs from the waste stream, which is a growing concern for natural habitats and drinking water. With extensive experience in groundwater remediation, it can bring solutions to emerging pollutant challenges.

Typical MBR wastewater quality
- According to municipal sewage
- BOD <5 mg/L (usually not detectable)
- TSS <5 mg/L (usually not detectable)
- NH3-N <1 mg/L (usually <0.5 mg/L)
- TN <10 mg/L (<3 mg/L can be achieved in warm climates)
- TP <0.5 mg/L (achievable <0.1 mg/L)
- Turbidity <1 NTU (95% of the time <0.2 NTU)
Discharge target (typical basic design)
- Discharge target (typical basic design)
- Biological oxygen demand (BOD) <5.0 mg / L
- Total suspended solids (TSS) <5.0 mg / L
- Ammonia nitrogen <1.0 mg/L
- Turbidity<0.5 NTU
- Total phosphorus <0.1 mg/L
- Total nitrogen <5.0 mg/L
- Enhanced nutrient removal design can achieve lower wastewater treatment effect:
- Total phosphorus <0.05 mg/L
- Total nitrogen <3.0 mg/L
