Brief introduction and Technical Specification
Flat Sheet MBR Introduction
Membrane bioreactor (MBR) is the combination of a membrane process like microfiltration or ultrafiltration with a biological wastewater treatment process and the activated sludge process. It is now widely used for municipal and industrial wastewater treatment. This bioreactor possesses the advantages of membrane filtration and biological treatment technology. Membrane modules, which can replace the secondary sedimentation tank, are used to separate mud and water. The MBR process has obvious advantages compared with the traditional wastewater treatment technology.
Traditional wastewater treatment process
Flat Sheet MBR Process
Flat Sheet MBR Advantages
Effluent high quality (low turbidity, low TSS) for regulatory or reuse purposes.
Not reliant on input water MLSS.
Longer activated sludge age and lower sludge disposal costs. Smaller footprint.
Easy operation.
The difference between the Flat Sheet MBR and Continuous Aeration System(CAS)
The water quality comparison of Flat Sheet MBR and CAS
Description | Input Water | Output Water | ||
Typical Municipal Wastewater |
| MBR | CAS | |
TURBIDITY (NTU) | - | Membrane Filtration Process | <1 | 5-20 |
SDI | - | <3 | >5 | |
TSS(mg/L) | 100-300 | <1 | 10-30 | |
BOD5(mg/L) | 300 | Biological Process | <5 | <30 |
COD(mg/L) | 600 | <30 | <100 | |
NH3-N(mg/L) | 30 | <0.5 | 5-10 | |
TN(mg/L) | 40 | <15 | >25 | |
TP(mg/L) | 10-20 | <0.5 | 5-8 | |
Note:
The removal rate of BOD and COD is related with the biological treatment process.
The removal rate of NH3-N is different based on the degree of nitrification.
The removal rate of TN is different based on the degree of denitrification.
The removal of the phosphorus might need the chemical method.
The other comparisons of Flat Sheet MBR and CAS
Description | MBR | CAS |
Water quality | Directly reusable, higher than national standard | Meet national standard |
Footprint | About 1/3-1/2 m²/(m³.d-1) | About 1m²/(m³.d-1) |
Construction investment | USD 300-400/(m³.d–1) | USD 250-300/(m³.d-1) |
Operation cost | USD 0.1-0.2 /m³ | < 0.1 USD/m³ (Direct water discharge) < 0.2 USD/m³ (Reclaimed water discharge) |
Excess sludge | 1/3-1/5 of CAS | Volume big, high processing cost |
Operations management | Few devices, simple flow process, easy to automatically control, stable operation and remote control feasible | Many devices, complicate flow process, easy to break down and high operation cost |
Water application | Reclaimed water and water for industrial use | Emission on standard |
Flat Sheet MBR benefits
flat sheet membrane is made of PVDF, which has better chemical stability, fouling resistance and mechanical strength. With advanced membrane fabrication technology, we control the membrane pore size around 0.1µm to get a higher water flux and water quality. The mortise and tenon structure is used in the support plate to get a more stable spacing without side panels. The support plate can be installed from top and installed from one side without the limits of the construction site conditions.
Laser engraving diamond flow path, coupled with special umbrella support structure, make the suction pressure distribution much better without diverting nonwoven fabrics. This structure reduces the risk of fouling and improves the water flow rate.

Note:
For different water quality, there will be a different water flow rate. So the user should fully test the membrane module.
This parameter is tested at 25℃,-10KPa suction vacuum conditions based on municipal wastewater.
