Moving Bed Biofilm Reactor Mbbr Carrier

MBBR biofilter media is a new high-tech patented product with a new type of microbes as carrier. According to the different kinds of sewage, Using scientific formula, it is formed from polymer material modification and restructuring through special process, which has same advantages of large specific surface, good hydrophilic property, strong.

Mobile bed biofilm reactor(MBBR) is an effecient biofilm technology,which combines the advantages of traditional fluidized bed.The MBBR process adds a certain amount of suspended filler(biofilm carrier)to the reactor,and in the protected area of the filler,different microorganisms(from bacteria to ciliates to rotifers)concentrate on the biofilm.Some anaerobic or aerobic bacteria are grown inside the carrier,while aerobic bacteria are grown outside. Each carrier is a micro-reactor,which ensures extensive and frequent contact between waste water and biofilms on the carrier,either through blast aeration in the aerobic treatment system or stirring in the anaerobic treatment system. While improving the mass transfer efficiency of the system,the renewal of biofilm microorganisms should be strengthened to maintain and improve the activity of biofilm. The suspended carrier and the original activated sludge form a more complex ecosystem and the biofilm attached to the carrier greatly increases the active biomass in the reactor. Under the joint action of suspended activated sludge and biofilm on the surface of suspended carrier,the impact load resistance capacity of the system is greatly improved, so as to improve the effeciency of sewage treatment and stabilize the effluent quality.
