Moving Bed Biological Reactor / Polyethylene Filter Media
Product Description
The moving bed biofilm reactor (MBBR) needs the suspended packing which has the characteristics of close proportion to water, large effective specific surface area, and suitable for microbial growth. The suspended packing can be suspended by slightly stirring in the biochemical tank, which is easy to move freely with the water and can form a good fluidization state.
Principle of action of fluidized bed packing when sewage passes through the fluidized bed packing reactor, microorganisms in the water continuously adhere to and grow on the inner and outer surfaces of the fluidized bed packing to form a biofilm. The fluid bed packing rotates freely under the agitation of the mixed liquid in the reactor. The biofilm fully contacts and decomposes the pollutants in the water body, so that the water quality can be purified. The turnover of mixed liquid and the movement of carrier are realized by aerobic aeration or anaerobic agitation.

Application
1. The fluidized bed biofilm reactor can be used to remove organic matters and nitrogen. The flow bed biofilm reactor process can be used to remove conventional pollutants, even nitrogen and other nutrients in wastewater. The process has the advantages of simple equipment, flexible operation, saving land occupation, convenient operation, and can be used independently, in series or in parallel. It can be used for the purposes of nitrogen and phosphorus removal, high concentration wastewater removal and sewage treatment The new construction, reconstruction and expansion of the plant can increase the load, improve the treatment effect, reduce the floor area, etc;
2. Combined with the characteristics of biofilm process and activated sludge process in the same treatment unit, the activated sludge process with flotation packing can improve the capacity of BOD / COD removal and the function of phosphorus and nitrogen removal of the existing activated sludge process. This method is suitable for the transformation of the traditional activated sludge method. Without new structures, the function and efficiency of the system can be improved;
3. Front out of stock;
4. Post sell out;
5. Applied to filtration of fish pond or high-purity Aquarium
Advantages
1. Fast start-up, short transformation and commissioning period;
2. Large biomass, strong resistance to impact load;
3. Save energy, land and investment;
4. It can be applied flexibly in aerobic, anoxic and anaerobic sections;
5. It is directly added without new structures:
6. It is especially suitable for the upgrading of wastewater treatment plant and the deep denitrification treatment;
7. The technology is also used in the construction of integrated equipment, which can effectively save 1 / 3-1 / 2 of the floor area compared with the conventional process, and the management is also simpler.
