Product Introduction
　　Combination filler is developed based on soft and semi-soft fillers, combining the advantages of both. Its structure replaces plastic discs with double-ring large plastic rings, pressing aldehyde fibers or polyester filaments onto the ring loops to ensure uniform distribution of fiber bundles; the inner ring consists of snowflake-shaped plastic branches, which not only support biofilm growth but also effectively cut bubbles, enhancing oxygen transfer rate and utilization. This allows full exchange of water, air, and biofilm, enabling efficient treatment of organic matter in water.

Application Scope
　　Widely used in wastewater treatment for printing and dyeing, silk and wool spinning, food, pharmaceuticals, petrochemicals, papermaking, cyanide-containing effluents, etc., making it highly popular among users.

Product Features
　　Advantages include large specific surface area, high oxygen utilization, variable porosity, no clogging, and broad applicability.
