Rosun - Membrane Bioreactor
As an MBR membrane manufacturer, Rosun provides types of MBR at a competive wholesale MBR membrane price. MBR reactor (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.

MBR Reactor Technical Process and Comparison
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 MBR filter 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.
Membrane Bioreactor 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 of membrane bioreactor processes principles and applications according to its efficacy area.
Membrane Biological Reactor Wastewater Treatment Advantages
Advanced material:
The main material of the MBR filtration is PVDF, which has excellent chemical stability, permeate flux, permeate quality, and fouling resistance.
Better outlet water quality:
As one of leading MBR membrane manufacturers, 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 and lower price:
Compared with hollow fiber curtain membrane, Rosun flat sheet have a longer service life of 3-6 years at lower mbr membrane price 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.
- Good outlet water quality
- Easy to control technological parameter
- High load capacity for impact
- Lower sludge output quantity
- Little areas occupation of land
- One-time installation, put into operation quickly, easy to maintain, automatic operation.
After MBR treatment there is almost no bacteria, outlet water quality is good. The outlet water Can be used as reclaimed water, widely used in the following areas.
Domestic and sewage treatment industry
- Municipal sewage treatment and water reuse
- Sewage treatment and water reuse
- Hospital wastewater and water reuse
- Residential area, school, scenic-tourist areas sewage treatment, ect.
Industrial wastewater treatment industry
Chemical, petroleum, chemical fiber wastewater treatment
Garbage leachate treatment
Pesticide, pharmaceutical high concentration organic wastewater treatment
Slaughter, livestock manure, food processing wastewater treatment
Brewing, beer wastewater treatment
In order to guarantee the normal, stable and long term operation of membrane unit. The raw water enters the MRB system has the below requirements:
