Structure and preparation requirements of sewage treatment air diffuser

- Jan 18, 2019 -

The sewage treatment air diffuser is used in the process of aerated biological filter for water treatment. In order to provide the oxygen required for the survival of microorganisms, the common biological filter generally adopts a ventilation hole in the lower part of the filter tank, and relies on natural ventilation to supply oxygen, which is easy to cause. The air supply pressure is unevenly distributed, and short-flow and local air-blocking phenomena occur. The natural ventilation oxygen supply is controlled by the difference among the temperature in the pool, the filter height, the filter material gap and the wind, and cannot provide stable and uniform ventilation to the filter.

The aerated biological filter replaces the natural ventilation and oxygen supply by forcing air into the filter layer of the filter to fully provide sufficient and stable oxygen for the microbial metabolism of the filter material to enhance the aeration to improve the overall effect of the biofilter.

Structure of sewage treatment air diffuser

The sewage treatment air diffuser is made of ABS and consists of an upper pipe clamp, a lower pipe clamp, a single-hole membrane (using EPDM rubber imported from Japan), and an ABS fixed adjustment bracket. The aerator is not affected by the difference between the temperature and the temperature in the pool, and is not affected by the height of the filter and the void ratio of the bioceramic filter material. The bubble diameter is small and the distribution range is large. The aerator outlet has a unique concave-convex structure and is not easy to be Blockage, not afraid of bioceramic filter material stacking pressure. Due to its special structure, it is necessary to operate according to relevant requirements during installation and use.
