Combination packing is developed on the basis of soft and semi-soft packing materials, combining the advantages of both. Its structure involves replacing the plastic disc buckle with a double-ring large plastic ring, pressing aldehyde-treated fibers or polyester filaments onto the ring loops to ensure uniform distribution of the 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 for full exchange of water, air, and biofilm, enabling efficient treatment of organic matter in water.
Application: 
        Used in sewage and wastewater treatment projects, paired with equipment such as contact oxidation towers, oxidation ponds, and oxidation tanks, serving as a biological carrier for wastewater treatment via biological contact oxidation and anaerobic fermentation methods.
Performance Characteristics: 
        Features high heat dissipation, low resistance, excellent water and air distribution, easy biofilm formation, and bubble-cutting effects.
Specifications: 
        Unit diameters: Φ150mm, Φ180mm, Φ200mm, with spacing options of 80mm and 100mm. Central ropes are available in plastic and fiber materials.
Ordering Information: 
        When ordering, please specify the required length, cubic volume, spacing, etc., of the combination packing.
