How long does it take for MBBR Carrier to debug at low temperature in winter?

In one month, it can achieve the standard well.

If the film is hanging, it is actually a process. We divide the film into two angles. The first one is that our naked eyes can see obvious biofilm on the filler. This time is seven days;

The second is the time to reach the standard, this time is probably within a month in winter；

The third is the time for the biofilm to fully mature, which will be longer, because from a professional point of view, the biofilm fully matures at least through a winter and summer alternation before the colonies on it can finally achieve stability.
