MBBR Carrier, treatment process, do I need to add additional biological agents?

MBBR does not require the addition of bacteria in the strict sense.

Then it is through reasonable optimization parameters, it can go to natural enrichment, such as our nitrifying bacteria or denitrifying bacteria, because its biofilm conditions are conducive to the attachment of related bacteria, such as anammonia. Also, under certain conditions, it is conducive to the attachment of our anammonia bacteria. Under special water conditions, for example, there are some refractory water quality or the source of water quality is relatively single, and some specific bacterial agents have special effects. , In this way, the inoculation can be done as the first inoculation, and the follow-up does not need to be added. To sum it up, it is not needed under the conditions of domestic sewage, and under some specific wastewater conditions, it can be used as a research proposition to do related research.
