● Product Introduction
Fluidized bed packing, also known as MBBR packing, is used in aerobic biological fluidized bed processes. The fluidized bed packing (MBBR) adopts a three-dimensional hollow structure as the aerobic biological carrier, and the packing is suspended in water during normal operation. Anaerobic bacteria grow inside the packing material, producing denitrification to remove nitrogen; Aerobic bacteria grow externally to remove organic matter, and both nitrification and denitrification processes occur during the entire treatment process. The fluidized bed packing (MBBR) process technology has the characteristic of high volumetric load, so the fluidized bed packing (MBBR) process can reduce the pool volume.
● Product features
1) The biological formation time is 3-15 days, and there is no need to culture bacteria beforehand.
2) Special surface treatment: rough inner surface, enhanced adhesion of micro cells and rapid formation of biofilm
3) Good hydrophilicity - adding hydrophilic groups to improve biofilm formation and biomass
4) Our MBBR filler has surface charge modification, which is suitable for the growth of most microorganisms.
5) Biomass 10-20 (g/m2)
6) Can remove BOD5, COD, TSS, etc
