Polypropylene (PP) plastic is made into a ball, which is composed oftwo hemispheres, each hemisphere has 8-12 semi-fan blades according to
the design needs, and the fan blades of both hemispheres are staggered with each other.The packing is characterized by a large specific surface
area and a high void ratio. However, due to the large number of blades, there is a shading effect between each other, which is not conducive to
liquid distribution and wetting; the liquidmostly accumulatesin the spherical hollow column, hindering the gasflow,so the resistance islarge.
This kind offilleris mostly used for waste gastreatment and watertreatment engineering
