The packing series is made of polypropylene material, which is divided into inner and outer double-layer spheres, the outer part is a hollow fish net-like sphere, and the inside is a rotating sphere. It mainly functions as a biofilm carrier and has the function of retaining suspended solids. It has strong bio-adhesion, large specific surface area, high porosity, good chemical and biological stability, durability, no harmful substances, no secondary damage. Pollution, UV protection, anti-aging, strong hydrophilic properties, etc., in the process of use, microorganisms are easy to generate, easy to replace, acid and alkali resistant, anti-aging, not affected by water flow, long service life, less residual sludge, easy to install .
1. Large specific surface area, high poriness
2. Strong ability of biological adhesion
3. Good hydrophilicity
4. Stable physical and chemical performance
5. No-harmful material, no second pollution
6. Long working life, protection from ultraviolet ray, resistance of aging
