The MBBR process is based on the basic principle of the biofilm process.
By adding a certain amount of suspended carrier into the reactor, the biomass and biological species in the reactor can be increased, thus the treatment efficiency of the reactor can be improved. Because the packing density is close to that of water, it is completely mixed with water when aerating. The environment of microorganism growth is gas, liquid and solid.

The collision and shearing of carriers in water make the air bubble smaller and increase the utilization ratio of oxygen. In addition, each carrier has a different type of organism inside and outside, with anaerobic or facultative bacteria growing inside and aerobic bacteria on the outside, so that each carrier is a Microreactor, allowing both nitrification and Denitrification to occur, thus improving the processing effect.
