Product Description Product DescriptionMbbr Bio Film CarrierIn the aerobic biological fluidized bed process, three-dimensional hollow packing serves as the aerobic biological carrier. The packing features a hollow structure and remains suspended in water during normal operation. Anaerobic bacteria grow inside the packing, enabling denitrification for nitrogen removal, while aerobic bacteria on the surface decompose organic matter. Both nitrification and denitrification processes occur simultaneously throughout the treatment.Advantages:High-Quality Materials: Made from premium copolymer materials, it does not degrade in wastewater and is non-toxic to microorganisms, superior to materials like PVC.Unique Structure: The hollow packing has a three-layered circular design with 1 internal rib and 36 external ribs, developed through extensive research and formed in one piece.Large Specific Surface Area: Offering a specific surface area of up to 600 m2/m3 (double-layered: over 860 m2/m3), significantly higher than traditional microbial carriers (90-180 m2/m3). This allows high biomass concentration per unit volume, reducing hydraulic retention time.High Microbial Activity: The biofilm on the packing surface remains in the logarithmic growth phase due to collisions and aeration scouring, ensuring efficient treatment.Floating Design: Easy to replace and long-lasting.Strong Nitrogen & Organic Removal: Effectively removes nitrogen and decomposes organic matter.Detailed Photos WorkshopProduct ParametersModel DiameterSpecific Surface AreaNumber of Packings per Unit VolumeBOD Oxidation EfficiencyCOD Oxidation Efficiency Nitrification EfficiencyBiofilm Formation TimePorosity Dosage Rate Φ1010*10>800>6300002000-100002000-15000400-12003-15days>8515-67Φ1515*10>1000>260000>85Φ2525*10>500>97000>90Key Features1.Premium Copolymer Material: Made from long-lasting copolymer (non-degradable in wastewater, non-toxic to microorganisms), superior to materials like PVC.2.Patented Three-Layer Design: Innovatively engineered with 3 hollow concentric layers (1 rib per inner layer, 36 ribs on the outer layer), formed in one seamless molding process.3.Ultra-High Specific Surface Area:Standard microbial carrier: 90-180 m2/m3This packing: 600 m2/m3 (dual-layer: 860+ m2/m3)4.High biomass per unit volume allows short hydraulic retention time.Hyperactive Microbial Film: Constant fluidization collisions and aeration scouring keep biofilms in the logarithmic growth phase, maximizing treatment efficiency.5.Floatable & Durable: Easy to replace, with a service life of ≥5 years (no sedimentation, no clogging).6.Strong Nitrogen/Organic Removal: Achieves nitrogen removal through integrated denitrification and organic decomposition. Usage and CasesIndustrial Wastewater Treatment:Usage Method:In a biological fluidized bed system for industrial effluent, polyurethane (PU) or polypropylene (PP) carriers of 5-15 mm diameter are used with a bed depth of 0.8-1.2 m; aeration intensity is maintained at 0.05-0.15 m3/(m2·h) and hydraulic retention time of 6-8 h to ensure complete degradation and nitrification-denitrificationCase:A seafood processing plant in Shandong used K3 cubic PU carriers (1×1×1 cm) in a 10 m3/h fluidized bed + secondary clarifier system, achieving 92% COD removal and 85% ammonia removalAnaerobic Digestion TankUsage Method:In an anaerobic fluidized bed reactor (AFBR), inorganic carriers (e.g., expanded clay or activated carbon) of 1-3 mm are used; operating temperature is 35-37 °C, HRT is 8-12 h, and superficial gas-solid velocity is kept at 0.5-1.0 m/h to maintain biofilm integrityCase:A Turkish winery upgraded its UASB to an anaerobic fluidized bed treating grape marc wastewater (COD 8 000 mg/L). With activated carbon packing, effluent COD dropped below 500 mg/L and methane yield reached 0.30 m3/kg COD_removed Company Profile
