KQ single hole film aerator
In biological aerated filter (BAF) process, in order to provide the oxygen for the survival of microorganisms, the common BAF generally uses the ventilation hole at the lower part of the filter, relying on the self-cleaning
The natural ventilation oxygen supply is controlled by the difference between the temperature in the pool and the air temperature,
It can not provide stable and uniform ventilation for the filter, and the biological aerated filter is replaced by forced air into the filter material layer
It can supply oxygen for natural ventilation, so as to provide sufficient and stable oxygen for the metabolism of microorganisms living on the biofilm filter material, so as to improve the aeration efficiency
The overall effect of the filter is good.
