Volcanic biological filter material

    Volcanic biological filter material product introduction:
    Volcanic biological filter materials,was born earliest in the United States, China once rely on the import to achieve biological hang membrane technology, due to its high cost, the scientific research personnel to develop the biological taoli to replace. Now, our company scientific research personnel through research in domestic found for machining volcanic filter material, after the mineral dressing, crushing, screening, grinding and so on a series of crafts processing from the particulate filter material, its main ingredients for silicon, aluminum, magnesium, sodium, calcium, iron, manganese, titanium, nickel and cobalt and molybdenum kinds of minerals and trace elements, apparent for irregular particles, color is red brown and black, qualitative light, porous particle size produced according to different requirements.
    Physical structure characteristics:
    Volcanic biological filter material's appear in physical microstructure aspects is rough surface, more microporous, these characteristics particularly suitable for microbes in their surface growth, reproduction, forming a biological membrane. Volcanic filter material make biological aerated filters can not only, and can handle municipal wastewater biochemical organic industrial waste water, drainage, micro life waste water etc, also can be in water treatment replace quartz sand, activated carbon, such as the filter medium anthracite, and can also to have been sewage treatment plant secondary process of tail water depth processing, its treatment do water reaches back after water standard for water reuse.
    Chemical structure characteristics:
    Volcanic biological filter material's appear in chemical microstructure showed for:
    1,Microbial chemistry stability: volcanic biological filter materials have corrosion, inert, in the environment does not participate in biological membrane biological chemistry.
    2,Surface electrical and hydrophilic: biological filter material volcanic surface has positive charge, be helpful for microbial a solid growth, hydrophilic strong, possessed biofilm quantity is excesive and speed.
    3, In the aspect of biological membrane activity: as biofilm carrier, volcanic biological filter material is fixed by microorganisms without inhibitory effect, harmless, proved does not affect the activity of microorganism.
