Manufacturer tell you :How to choose MBBR biofiller?

MBBR Material

The MBBR process is a new process of one-time dosing and does not need to replace the biological filler, so the requirements for the material are very high. Generally, the life of the biological filler made of high-purity HDPE material can reach more than 15 years. If inferior materials are used, it is easy to cause the biological filler to break and block the pipeline in the later use project.

Factory Production technology level

The structure of biological fillers is designed by fluid mechanics, which are generally round and porous. In the production process, the production process and technology of the producer are extremely demanding. From the development of the mold to the professional production machine and the temperature in the production process, Speed ​​tuning is important. For example, some biological fillers with uneven wall thickness are prone to insufficient toughness.

Specific surface area of biological filler

The specific surface area of ​​the biological filler directly affects the number of microorganisms cultivated in a unit cubic water body, and the more microorganisms cultivated, the stronger the ability to treat sewage. However, in the actual selection of fillers, not only the specific surface area of ​​biological fillers, but also the diameter and pore size of the fillers are also considered. The diameter of the filler is related to the pore size of the intercepting net. The pore size of the filler will not only affect the specific surface area, but also whether the aging biofilm is easy to fall off. At present, some MBBR biofillers on the market have a large specific surface area, but the pores are small, and the effect of pre-filming and post-treatment is very good. However, after one or two years of actual operation, the aging biofilm cannot fall off, resulting in the failure of water quality in the later stage. MBBR biological filler has the advantages of large specific surface area, good hydrophilicity, good fluidity, high biological activity, easy to hang film, good treatment effect and long service life, so MBBR process will be widely used in more sewage treatment projects.

Therefore, it is particularly important to choose a filler with good quality and satisfactory price.
