1.Designed according to fluid mechanics, enhanced surface adhesion, specially designed geometry, with a large effective specific surface area;
2.The filler is made of macromolecular material, which is modified and has strong impact resistance;
3.Advanced surface treatment technology is more conducive to the adhesion growth of microorganisms;
4.The special structure and geometric size of packing improve the mass transfer efficiency of the system.
5.The packing has large specific surface area, large adhesion biomass and high abundance
6.With a large specific surface area, providing support for a large number of microbial attachment growth

7.It is beneficial to the growth of various microorganisms, not only provides space for the growth of heterotrophic bacteria, but also creates conditions for the growth of autotrophic bacteria, laying a solid foundation for biological nitrogen and phosphorus removal.

8.No need for brackets, easy fluidization, energy saving proper weight(0.97～0.98 before hanging membrane,1 after hanging membrane),the filler is in a floating state when the gas is stopped, and is in a suspended fluidized state under aeration to minimize the energy consumption;
9.The fluidization of the filler increases the impact and cutting of the bubbles, improves the utilization of oxygen, and reduces the energy consumption of the aeration. Under the same conditions, the aeration can be reduced by more than 10%.
10.Save space, increase processing capacity and effect by increasing filling rate, no need to add new structures.
