Unlike traditional fixed packing that suffers from uneven biofilm distribution, easy clogging, and difficult maintenance, our Suspended Ball Filler solves these industry pain points through its unique floating design. The hollow spherical structure allows it to suspend freely in the treatment tank, moving with aeration and water flow to ensure full contact between the packing, water, and gas. The porous inner core (filled with fiber bundles or porous ceramic particles) provides a large specific surface area for microbial attachment, while the permeable outer shell protects the biofilm from shear damage and promotes uniform mass transfer. This design eliminates dead zones, avoids clogging, and simplifies maintenance, making it an ideal choice for efficient, low-maintenance water treatment systems globally.

Product Feature
Core Working Principle
Our Suspended Ball Filleroperates based on the MBBR (Moving Bed Biofilm Reactor) principle, relying on its unique floating structure and porous design to realize efficient biofilm growth and pollutant degradation. It integrates seamlessly with various water treatment processes, achieving optimal solid-liquid-gas mass transfer and microbial metabolism:
1.Free Suspension & Fluidization: The hollow spherical structure (with a specific gravity slightly less than water, 0.90–0.98 g/cm³) enables the packing to suspend freely in the treatment tank. Under the action of aeration or water flow, it achieves full fluidization, moving uniformly throughout the tank and ensuring no local dead zones. This maximizes the contact area between the packing, wastewater, and air, laying a foundation for efficient biofilm growth and pollutant degradation.
2.Microbial Attachment & Biofilm Formation: The porous inner core (filled with hydrophilic fiber bundles or porous ceramic particles) has a large specific surface area (300–1200 m²/m³ depending on specifications), providing ample attachment sites for microorganisms. The hydrophilic surface of the inner core accelerates microbial colonization, enabling stable biofilm formation in 5–7 days. The permeable outer shell (with uniform pores of 2–5mm) protects the biofilm from shear damage caused by strong aeration or water flow, ensuring the biofilm remains intact and active.
3.Pollutant Degradation & Mass Transfer: As the suspension ball moves freely in the tank, the biofilm on the inner core fully contacts the pollutants in the wastewater. Aerobic microorganisms on the outer layer of the biofilm decompose organic matter, ammonia nitrogen, and phosphorus into harmless substances (CO₂, H₂O, nitrogen gas), while anaerobic microorganisms in the inner layer complete denitrification, improving nitrogen removal efficiency . The fluidization of the packing enhances gas-liquid mass transfer, increasing oxygen utilization rate by 25–35%, and promoting efficient biochemical reactions.
4.Biofilm Renewal & Anti-Clogging: During fluidization, the suspension balls collide and rub against each other, which automatically peels off aged, inactive biofilm—ensuring the biofilm remains active and efficient. The hollow structure and permeable outer shell prevent sludge accumulation and clogging, even in wastewater with high suspended solids (SS) content. This reduces manual cleaning frequency and ensures stable long-term operation.
Key Product Advantages
1.Efficient Fluidization & No Dead Zones: The hollow spherical design with optimized specific gravity enables free suspension and uniform fluidization in water, ensuring the packing moves throughout the treatment tank without local dead zones. This maximizes the contact efficiency between biofilm, wastewater, and air, significantly improving pollutant degradation efficiency.
2.Rapid Biofilm Formation & High Microbial Biomass: The porous inner core with a large specific surface area (300–1200 m²/m³) and hydrophilic surface accelerates microbial colonization, with stable biofilm formation in 5–7 days. The biofilm weight can reach 60–90 kg/m³, significantly increasing microbial biomass and enhancing the degradation efficiency of COD, ammonia nitrogen, and phosphorus.
3.Anti-Clogging & Self-Renewing: The fluidization and mutual collision of the suspension balls realize automatic biofilm renewal, avoiding aged biofilm accumulation. The permeable outer shell and hollow structure prevent sludge clogging, reducing manual cleaning frequency and maintenance workload. It is suitable for wastewater with high SS content (≤500 mg/L).
4.Strong Corrosion Resistance & Durability: Made of high-quality engineering plastics (PP, PE) or modified PVC, mixed with anti-aging, anti-oxidation, and hydrophilic additives. It can withstand long-term operation in acidic, alkaline, and high-salt wastewater (pH 2–12) and has a service life of 3–6 years, which is longer than ordinary biofilm carriers. The outer shell is impact-resistant, not easy to break during fluidization and transportation.
5.Energy-Saving & Cost-Effective: The light weight and smooth surface of the suspension ball reduce water flow and aeration resistance, lowering fan energy consumption by 15–20%. The self-cleaning function and long service life reduce maintenance and replacement costs, while the high treatment efficiency shortens the retention time, reducing the tank volume and civil engineering investment.
6.Flexible Specifications & Customization: Available in standard specifications (diameter 50mm, 80mm, 100mm, 120mm) with different inner core materials (fiber bundles, porous ceramic, activated carbon). We provide customized solutions (size, specific gravity, inner core material) according to the treatment process (MBBR, biological contact oxidation), water quality, and tank size, ensuring perfect adaptation to different project needs.
7.Easy Installation & Maintenance: No fixed brackets or installation structures are required—just add the packing directly into the treatment tank, reducing installation time and labor costs. The floating design allows for easy inspection and replacement; when maintenance is needed, the packing can be fished out with a net without stopping production.
8.Wide Adaptability & Versatility: Suitable for various water treatment processes, including MBBR, biological contact oxidation, hydrolysis acidification, and aquaculture water purification. It can adapt to fluctuations in wastewater quality (COD 200–6000 mg/L) and flow, with strong impact load resistance, making it ideal for municipal sewage and industrial wastewater (printing and dyeing, papermaking, pharmaceutical, food, petrochemical) treatment.
9.Global Compliance & Environmental Friendliness: The raw materials are non-toxic, non-polluting, and comply with ISO 14001:2015 environmental standards. The product fully meets international water treatment standards and regional regulations (EU, US EPA), helping customers smoothly pass environmental inspections and meet sustainable development goals.
