Strong hang membrane filtering material
 Brief introduction

     Strong hang membrane filtering material is a high effective Strong hang membrane filtering material, . It has got broad applications:
    HB-I types can be used as filtering material of various filteration pool ;
    HB-II can be used as carrier of high loaded biological filtration pool, or applied in the biological filtration pool of tap-water, the coarse granulation materiaql of oil bearing water, ion exchange resin and drying storage of microorganism
    HB-III types can be used in the deep treatment of drinkable wate
     According to the different water quality, we develop special modified filteration material

 Application of Strong hang membrane filtering material in BAF craft

    It has both functions of biochemical degradation & adsorption filtration. It increase the sewage load greatly. It keeps the advantages of traditional ceramsite, and it has solved the problem of back flush.
