MBBR Fish Pond Moving Bed Biofilm Reactor
Introduce：
The ideal requirements can be fulfilled by the use of thin, disc-shaped and porous carriers, whereas an optimal and active biofilm establishes inside of the pores and any excess sludge is removed by shear forces. The shear forces occur when the disc surfaces come into contact with each other due to the movement of the carriers in the wastewater (reaction tank).When using tubular carriers, it is not possible to benefit from the shear forces effect in the inner zones of the carriers, which has been proven to be a significant disadvantage. When using stable, porous, disc-shaped carriers with a thickness of 1.0 – 1.2 mm, the active biofilm can establish inside of the pores and so the supply with substrates can be effected from both sides of the carrier.Another requirement to be fulfilled is the maximum reduction of wear. In most cases, the reason for the occurrence of wear and abrasion of carriers is the kinetic energy, i.e. the energy which is required for slowing-down a body which is moved in the water. Any non-elastic, large and heavy tubular/hollow body carriers which possibly even contain a huge amount of dead biomass, exhibit a disadvantageous kinetic behaviour compared to lightweight, flexible disc-shaped carriers. Flexible "buffer zones" in the plastic material maximally reduce the wear. Additionally, the biofilm serves as a lubricant layer.MBBR Fish Pond Moving Bed Biofilm Reactor

MBBR Fish Pond Moving Bed Biofilm Reactor To summarize, it can be stated that the biological removal rate which is calculated by the respective manufacturer, and not solely the surface area, serves to determine the removal target. During the plant operation, an optimal carrier geometry is a vital requirement for appropriately meeting the biological demands and so ensuring the optimal development of the biofilm.
