In the BAF process, in order to provide the oxygen needed for the survival of microorganisms, the common biological filter generally adopts a vent at the lower part of the filter, which relies on natural ventilation for oxygen supply. In this way, it is easy to cause uneven distribution of air supply pressure, short flow and local air blockage. The natural ventilation and oxygen supply are controlled by the difference between the temperature and air temperature in the tank, the height of the filter, the gap between the filter materials and the wind force The BAF can not provide stable and even ventilation for the filter. The BAF can replace the natural ventilation and oxygen supply by forcing air into the filter material layer of the filter, so as to completely provide enough and stable oxygen for the metabolism of microorganisms living on the biofilm biofilter, so as to improve the overall effect of the BAF.


It is not controlled by the difference between the temperature in the tank and the air temperature, the height of the filter tank and the void ratio of the biofilm filter material. The bubble diameter is small, and the bubble distribution range is large. Because of the concave convex points at the outlet of the aerator, it is not easy to be blocked, and it is not afraid of the stack pressure of the biofilm filter material.


The ventilation branch pipe and branch pipe are made of abs-upvc plastic rigid pipe, which is composed of upper pipe clamp, lower pipe clamp, single hole membrane, ABS fixed adjustment bracket, etc.
