MBR (Membrane Bio-reactor) is a membrane separation technology with biological degradation. The membrane module can take the places of the secondary sedimentation tank, a large number of microorganisms are intercepted, which can increase the quantity of microflora, improve the sewage treatment capacity and efficiency, so that the effluent quality and volume load have been greatly improved, and the water can be used as reclaimed water.

The core component of the MBR is high-performance submerged membrane components. Compare with the traditional method (pressure filter), the membrane negative pressure suction type filtering method using aeration to operation a sable mbr filter membrane in the system.

Technical Process and Comparison of Membrane Bioreactor

The pollutant in sewage water will firstly biodegradation in a bioreactor, at the same time, because of the function of the pressure difference, the water, and some small-molecule solute which smaller than the aperture of the membrane in the mixed liquid will pass the membrane, and then become the treated water.

Microorganisms and macro solute will be intercepted by the membrane, so it replaced the sedimentation tank by complete its water treatment and separate function.

MBR Working Principle

Use the PVDF as the main material, Rosun flat sheet membrane with good stability of chemicals used in wastewater treatment, fouling resistance, and mechanical strength, has different types according to its efficacy area.

Advantages of biological reactor wastewater treatment

Advanced material:

The main material of the membrane is PVDF, which has excellent chemical stability, permeate flux, permeate quality, and fouling resistance.

Better outlet water quality:

The pore size of Rosun flat sheet membrane is around 0.1micron, and with advanced membrane technology increased the effective orifice area of the membrane surface then leads to excellent permeate flux and permeate quality. The output water can be reused directly.
