Product Specification

100% Virgin HDPE MBBR Filter Media For Industrial Wastewater Treatment

                                   Product Description                      

Fluidized bed packing, also known as MBBR packing, is a new type of bioactive carrier. It adopts scientific formula, according to different water quality requirements, integrates different kinds of Microelements in polymer materials, which are conducive to the rapid growth of microorganisms. After special process modification and construction, it has the advantages of large specific surface area, good hydrophilicity, good fluidity, high biological activity, easy to hang membrane, good treatment effect, long service life and so on.

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.

1.  Adhesion of biofilm

Adhesion capacity of biofilm - the most important index to evaluate the quality of fillers: biological adhesion = protected surface area (connected with the design of fillers

2.  Filler performance

Performance of packing - the most important index to evaluate the biological adhesion of packing

(1) Surface properties of fillers

1. Surface structure: it is generally considered that the surface roughness is large and the film hanging speed is fast.

2. Surface potential: generally, microorganisms are negatively charged, and the surface of filler is positively charged, which is suitable for microbial growth. 3. Hydrophilicity: the microorganism is hydrophilic particle, and the filler has good hydrophilicity and is suitable for microorganism growth.

(2) Hydraulic properties

1. Porosity: volume occupied by filler, high porosity.

2. Shape and size: affect the flow pattern of water and air flow.

(3) Fluidization performance: it is related to the density of filler. The density of the packing should be 0.97-1.03, and fluidization can be achieved with less aeration or agitation.

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;
