11 kinds of fillers Media used in sewage treatment-their use and performance comparison
Fillers are commonly used auxiliary materials in sewage treatment. They are generally divided into fillers for film-hanging, sedimentation, and blow-off. Because the fillers are cheap and effective, they will be used for some tight land or for upgrading. We also have natural fillings (i.e. quartz sand, zeolite and clay) also support microbial growth, but not as well.
However, due to some limitations of the fillers, Not every process is suitable. As a professional filler manufacturer, Hangzhou Aquasust plastic manufacture hopes to provide you with some useful information.

Classification and use of sewage treatment filler media
1. Moving bed bio reactor (MBBR)
Suitable for craft: freely placed in the pool
Installation method: Frame tied and suspended
Specific surface area: larger
Composition: HDPE
Scope of application: It is suitable for remote water treatment of tap water with good effect. It can also be used for anaerobic tanks, aeration tanks, and biological fluidized beds of sewage treatment plants. Higher cost and higher cost performance.
Fluidized packing is also called MBBR packing. The aerobic biological fluidized bed process adopts a three-dimensional hollow packing as an aerobic biological carrier. The packing is a hollow structure. It enters normally and the packing is suspended in water. The growth of anaerobic bacteria inside the filler, denitrification can be denitrification; external growth of aerobic bacteria, removal of organic matter, the entire process of simultaneous nitrification and denitrification process.
