MBBR Biofilm Media

 

Product description

Moving Bed Biological Reactor (MBBR media biofilm carrier) process is the new waste water treatment process developed by it combined the advantages of traditional Fluid Bed process and Biological Touch-Oxidation process, has good effect on denitrification and dephosphorization, it is widely used in the industrial waste water treatment and municipal waste water treatment.

Process principal:
The waste water go through the suspending media of MBBR( Biofilm carrier)reactor, form the biological membrane on the surface of the media gradually, with the action of the microbial on the biological membrane, the waste water is purified. The media can move freely in the reactor with the mixing of the water; For the aerobic reactor, the aeration will make the media move; For the anaerobic reactor, mechanic mixing will make the media move.

 Applied process and range:

(1) Thermofor biofilm reactor to remove organics and denitrify
(2) Active sludge process
It combines biofilm and activated sludge process in the same treatment unit. it improve the ability to remove BOD/COD and strengthen the function of denitrification and dephosphorization. such process is suitable for the remounlding of activated sludge process, no need of rebuilding.
(3)Preposition denitration.

  Using Advantage of Moving Bed Bioreactors Filter Media MBBR
1. Rapid carrier biofilm formation mechanism
2. uper decarburization, ammonia nitrogen removal capacity
3. Excellent resistance to shock load performance
4. Application of flexible and diverse way
5. Simple operation and maintenance
6. Long service life
