Submerged Flat Sheet MBR Membrane for Sewage Treatment with PVDF material 0.1um pore size

Flat Sheet MBR Membrane Bioreactor

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

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.

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.
