 PE04 HDPE Filter Media Mbbr Carrier Media For Sewage Treatment

                                   Product Description                      

MBBR packing is a microbial carrier used in MBBR Process, which is mainly to provide a suitable environment for the growth of microorganisms.

MBBR filler is a new type of bioactive carrier, which adopts scientific formula. According to the different nature of sewage, it is composed of a variety of microelements which are conducive to the rapid attachment and growth of microorganisms in polymer materials. After special process modification and construction, MBBR filler has the advantages of large specific surface area, good hydrophilicity, high bioactivity, fast film hanging, good treatment effect and long service life.

The core of MBBR Process is biological carrier and operation control technology;

The biological carrier is the product of the close combination of materials science and biology;

Biological carrier is a superior biological selector, especially in the refractory wastewater.

                                        Product Features                           

MBBR Process has the advantages of both traditional fluidized bed and biological contact oxidation process. It is a new and efficient sewage treatment method. The carrier is in the fluidization state by the enhancement of aeration and water flow in the aeration tank, and then the suspended activated sludge and the attached biofilm are formed. This makes the whole reactor space used by the moving bed biofilm, and the attached biofilm is fully utilized The advantages of phase and suspended phase make them complement each other. Different from the previous packing, the suspended packing can contact with sewage frequently and many times, so it is called "moving biofilm".

The key of MBBR technology is to research and develop the bio filler which has a specific gravity close to that of water and is easy to move freely with water under slight agitation. It has the characteristics of large effective specific surface area, suitable for microbial adsorption growth, strong applicability and wide application range. It can be used for both organic matter removal and nitrogen and phosphorus removal; It can be used not only in the new sewage treatment plant, but also in the process transformation and upgrading of the existing sewage treatment plant.

                        Process characteristics                         

The filling rate of biological packing in the reactor can reach 67%;

In aerobic reactor, aeration makes the biological packing flow (or suspend) in the whole reactor with the water mass in the reactor;

In the anaerobic reactor, the biological filler flows (or suspends) in the whole reactor with the water mass in the reactor;

Physical elements of process: tank body (various shapes and materials), filler, mixing facilities (aeration or diving mixing), water outlet device (various forms of screen).

                            Technology Parameter                       

                           Process advantages                            

(1) High volume load, compact land saving, especially for the upgrading of existing sewage treatment plants (facilities), the effect is significant. Without increasing the land area, only simple transformation of existing facilities is needed, the sewage treatment capacity can be increased by 2-3 times, and the effluent quality can be improved. The moving bed biofilm process covers an area of 20-30%.

(2) Strong impact resistance, stable performance and reliable operation. The effect of impact load and temperature change on moving bed process is far less than that on activated sludge process. When the composition of sewage changes or the toxicity of sewage increases, the biofilm has a strong stress on it.

(3) The mixing and aeration system is easy to operate and maintain. The aeration system adopts perforated aeration pipe system, which is not easy to block. The agitator adopts banana type agitating blade, with soft outline and without damaging the packing. The whole mixing and aeration system is easy to maintain and manage.

(4) There is no blockage in the biological pool, the volume of the biological pool is fully utilized, and there is no dead angle.. Because the packing and water flow can be mixed in the whole volume of the biological pool, the possibility of blockage of the biological pool is fundamentally eliminated, so the pool capacity is fully utilized.

(5) Flexible and convenient. The flexibility of the process is reflected in two aspects. On the one hand, all kinds of pool types (deep and shallow square circle) can be used without affecting the treatment effect of the process. On the other hand, it can be very flexible to choose different filler filling rates, so as to meet the requirements of both high efficiency and long-term expansion of treatment scale without increasing tank capacity. For the reconstruction and upgrading of the original activated sludge treatment plant, the fluidized bed biofilm process can be easily combined with the original process to form the integrated process of activated sludge biofilm or the combined process of fluidized bed activated sludge.

(6) Long service life. High quality and durable biological packing, aeration system and effluent device can ensure the long-term use of the whole system without replacement, and the depreciation rate is low.
