Porous spherical suspended packing
The porous spherical suspended packing is divided into two parts. The outer structure is two mesh spheres. The internal structure is a rotating fan or other special packing. It mainly acts as a biofilm carrier while intercepting suspended solids. At the same time, it has the function of suspending suspended solids. It has the characteristics of strong biological adhesion, high specific surface area, high porosity, good chemical and biological stability, durability, insoluble harmful substances, no secondary pollution, UV protection, anti-aging and strong hydrophilicity. In the process of use, microorganisms are easy to produce, easy to replace, acid and alkali resistant, anti-aging and not affected by water flow. It has the advantages of long service life, less sludge and convenient installation.
