ABF series air purification biological filter material universal type. This series of products adopts international patented technology, a layer of active adsorption material is compounded on the surface of natural or artificial inorganic filter material, and microorganisms are dissolved in promoting growth factors, making it easier for microorganisms to fix, grow, and adsorb in the air purification environment. Convert harmful components and improve the treatment range, work efficiency and efficiency of the biochemical treatment system.
This type of filter material has the characteristics of good hygroscopicity and permeability, easy to fix growth of microorganisms and not easy to block, strong adsorption and degradation ability of common pollutants in the air, and durability. It is suitable for deodorization of various sewage plants and sludge waste treatment facilities and VOC emission control of various factories and enterprises. It is used to remove H2S, sulfide, mercaptan, and various VOCs and other air pollution components.
A biofilm grows on the surface of ABF-C after hanging film in water for 30 days. However, the surface of abF-C is still clean after hanging film in water for 45 days without obvious biofilm growth
