Bio Media

1.How long will it take for packing to hang biofilm during low temperature in winter?

In a month can be a good one to achieve the standard. If the membrane hanging is actually a process, we divide the membrane hanging into two angles, the first is that our naked eyes can see obvious biofilm on the filler, this time is seven days; The second is the standard time, this time in winter is about within a month; The third is the time for the biofilm to fully mature, which will be longer, because from a professional perspective, the full maturity of the biofilm should go through at least one alternate winter and summer, so that the colony on it can finally achieve stability. In conclusion, although from an academic point of view, our stability is probably after a winter and summer, from the point of view of our effect, the water can reach the standard within 30 days, and from the point of view of visual recognition, it is about seven days.

2.What is the core technology for MBBR media?

One is packing, the other is fluidization, packing as a carrier, there isn't an unified research shows that its performance have big influence, but the shape convection is influential, so the most widely used shape from the domestic and international application is oblate column packing, you can try different fillers and see what works best. However, from the perspective of engineering, the dimensions to be evaluated include performance, film hanging speed, final stability effect, life, wear resistance and so on. Therefore, from the point of view , the core of suspension carrier is still on fluidization.

3.Is the filler prone to sludge bulking?

The main cause of sludge bulking is filamentous bacteria, so reports from abroad show that the filler helps to weaken sludge bulking, because it can break the "long" filamentous bacteria in the sludge system. If it is normal sludge floc, and the size of the sludge floc is much smaller than the size of the filler, it will not break the sludge. Therefore, MBBR is beneficial to improve the sludge settling ability from foreign studies, and from our engineering practice, we have not found that the system using MBBR has obvious characteristics of sludge bulking.

4.Does MBRB media need a denitrifying wash?

Compared with traditional bioflms, the biggest advantage of MBBR is it doesn't need backwashing, because the biofilm automatically falls off. What we found from our research is that when you have a more active biofilm, it has more exudates of extracellular polymers, and it has a higher viscosity. So when it ages, its extracellular secretions decrease, its viscosity decreases, it automatically falls off in the fluidization process, and then new biofilms grow up, so it doesn't need to be washed.
