In the aerated biological filter process, in order to provide the oxygen needed for the survival of microorganisms, ordinary biological filters generally use ventilation holes in the lower part of the filter and rely on natural ventilation to supply oxygen. This can easily cause uneven distribution of air supply pressure, resulting in Due to the phenomenon of short flow and local air blockage, the natural ventilation oxygen supply is controlled by the difference between the temperature in the pool and the air temperature, the height of the filter, the gap of the filter material and the wind force. It cannot provide stable and uniform ventilation to the filter. The aerated biological filter passes to Air is forced into the filter material layer of the filter to replace natural ventilation and oxygen supply, so as to fully provide sufficient and stable oxygen required for the metabolism of microorganisms living on the bio-ceramic filter material to improve aeration biological filtration. The overall effect of the pool.
Features
Subject to the difference between the temperature in the pool and the air temperature, and not controlled by the height of the filter and the porosity of the film-bearing bioceramsite filter material, the bubble diameter is small and the bubble distribution range is large, because the aerator outlet has The concave and convex sections are not easily clogged, and there is no fear of accumulation of film-forming bioceramsite filter media.
Structure
The gas distribution pipe and branch pipe are made of
plastic hard pipe, made of
, consisting of upper pipe clamp, lower pipe clamp, single-hole membrane,
Composed of fixed adjustment brackets, etc.
