Membrane Bioreactor
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 membranein 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.

Higher activated sludge adaption of Membrane Bioreactor:
Compared with the hollow fiber curtain membrane whose activated sludge adaption is only 4000-6000mg/L, Rosun flat sheet membrane can adapt 8000-15000mg/L activated sludge.
Longer service life:
Compared with hollow fiber curtain membrane, Rosun flat sheet have a longer service life of 3-6 years compared with 1-3years of service life of hollow fiber curtain membrane.
Less land space:
The MBR reactor tank can replace the function of a secondary sedimentation tank with an anaerobic tank, it can save 30% of land space.
Easy to operate and maintenance:
The flat sheet membrane can be just replaced a single damaged piece without change the holder when damage and replacement, replace just need 15 minutes.

MBR Membrane Bioreactor Design Module
Rosun MBR membrane module is combined with the membrane element box and the aeration box. The membrane outlet is combined by a water collection tube in the membrane element box, and each membrane element can be individually installed and unloaded for easy maintenance. For the upgrade of traditional technology, just install the membrane module in the aeration tank is ok.
