Main selection factors for MBBR carrier media
- Oct 18, 2018 -

At present, the MBBR carrier medium treatment process has received more and more attention, especially in the field of scale expansion and small integrated equipment of sewage plants. The MBBR carrier medium treatment process is playing an increasingly important role in wastewater treatment in China due to its low cost and high efficiency.


In fact, the MBBR carrier medium is the core of the process, and its quality will directly affect the processing effect of the processing system. There are many kinds of MBBR carriers, the specifications are different, and the actual effect is quite different, so it is very important to choose a suitable carrier medium. First of all, considering the long-term operation, the carrier material must have the characteristics of anti-wear, anti-corrosion and non-deformation.


The second choice is the specific surface area, since the amount of biomass that can be attached to the MBBR carrier medium depends primarily on the specific surface area. Generally, the larger the specific surface area, the larger the carrier attachable biomass, the smaller the amount of carrier to be added, the smaller the requirement for fluidization, and the lower the energy consumption. In addition, factors such as the hydraulic properties of the MBBR carrier medium should be considered.
