Product description 

The MBBR process combines the advantages of both traditional fluidized bed and biological contact oxidation methods. It is a new and efficient sewage treatment method that relies on aeration in the aeration tank and the lifting effect of water flow to keep the carrier in a fluidized state, thereby forming a suspension. The growing activated sludge and attached biofilm make the moving bed biofilm use the entire reactor space, giving full play to the advantages of both attached phase and suspended phase organisms, so that they can maximize their strengths and avoid weaknesses and complement each other. Different from previous fillers, suspended fillers can frequently come into contact with sewage and are therefore called "Moving Bed Biofilm Reactor."

Product feature

Compared with the activated sludge method and the fixed-fill biofilm method, MBBR not only has the high efficiency and operational 

flexibility of the activated sludge method, but also has the characteristics of the traditional biofilm method: resistance to shock load,

 long sludge age, and less residual sludge. 

(1) Filler characteristics. The fillers are mostly made of polyethylene, polypropylene and their modified materials, polyurethane foam, etc. 

The specific gravity is close to water, and they are mainly cylindrical and spherical. They are easy to film, do not agglomerate, do not block,

 and are easy to peel off.

(2) Good denitrification ability. A good nutrient, anoxic and anaerobic environment is formed on the filler, and nitrification and denitrification 

reactions can occur in one reactor, which has a good effect on the removal of ammonia nitrogen.

(3) Effective in removing organic matter. The sludge concentration in the reactor is high. Generally, the sludge concentration is 5 to 10 times 

that of the ordinary activated sludge method, and can be as high as 30 to 40g/L. It improves the processing efficiency of organic matter and 

has strong impact load resistance.

(4) Easy to maintain and manage. There is no need to install a packing bracket in the aeration tank, and the maintenance of the packing 

and the aeration device at the bottom of the tank is convenient, while saving investment and floor space.
