The structure of the packing is that the original plastic discs are changed into double-circle big plastic ring with the aldehyde fiber or polyester yarn pressed against the ring so that the fiber bundles will be evenly distributed; the inner ring of the packing is snowflake-shaped plastic branches, which can not only support the biological membrane, but can effectively cut the air bubble for purpose of increasing the oxygen transfer rate and utilization. In this way, the air-water will get full exchange on the biological membrane resulting in efficient treatment of the organics in water.
