Biofilm effect of MBBR

When the wastewater passes through the MBBR packing reactor, the microorganisms in the water continuously adhere to the inner and outer surface of the fluidized bed packing to form biofilm. The mixed liquid in the MBBR packing bioreactor rotates freely under the overturning, and the biofilm contacts with the pollutants in the water and decomposes them, so that the water quality can be purified. The turnover of the mixture and the movement of the carrier are realized by aerobic aeration or anaerobic stirring.

Characteristics of MBBR filler:

1. Direct delivery, no need to fix

2. Easy to form film without backwashing

3. Stable material and long service life

4. Large specific surface area and small head loss

5. Easy to design, install, maintain and replace

6. High oxygen transfer efficiency and energy saving

7. Phosphorus and nitrogen can be removed

8. High operation flexibility and organic load
