Introduction:
     In the biological aerated filter process, to provide the oxygen required for microbial survival, ordinary biological filters typically use ventilation holes at the bottom of the filter, relying on natural ventilation for oxygen supply. This can easily lead to uneven distribution of air pressure, short-circuiting, and local air blockage. Natural ventilation oxygen supply is controlled by the temperature difference between the pool and the air, the height of the filter, the void space of the filter media, and wind conditions, and cannot provide stable and uniform ventilation to the filter. The biological aerated filter replaces natural ventilation by forcibly introducing air into the filter media layer to fully supply sufficient and stable oxygen for the metabolism of microorganisms living on the biofilm-coated ceramic filter media, thereby improving the overall efficiency of the biological aerated filter.
Features:
    Not affected by the temperature difference between the pool and the air, nor by the height of the filter or the voidage of the biofilm-coated ceramic filter media. The bubble diameter is small, and the bubble distribution range is wide. The aerator outlet has a concave-convex design that is not easily clogged and is resistant to pressure from the biofilm-coated ceramic filter media.
Structure:
    The air distribution and branch pipes are made of ABS-UPVC plastic hard pipes. The aerator is made of ABS and consists of an upper pipe clamp, lower pipe clamp, single orifice membrane, ABS fixed adjustment bracket, and other components.
