MBBR Biofilm Carrier Media HDPE Bio Filter Media for Wastewater Treatment Plant 12x9mm K1 Type

MBBR Biofilm Carrier Media for Wastewater Treatment

Our MBBR Biofilm Carrier Media (Model BM-K5) is a premium HDPE biological filter media designed for Moving Bed Biofilm Reactor (MBBR) and Integrated Fixed-Film Activated Sludge (IFAS) systems. The 25*12mm cylindrical design with internal cross structure provides 800 m²/m³ of protected surface area for biofilm attachment, enabling high-rate BOD removal, nitrification, and denitrification in compact reactor volumes. Trusted by wastewater treatment plants across Brazil, Mexico, Chile, Colombia, Argentina, and Peru.

Key Features & Benefits

• High Protected Surface Area: 800 m²/m³ internal cross design shields biofilm from shear forces during aeration and mixing, ensuring stable biomass retention even under hydraulic shock loads.
• Virgin HDPE Material: Manufactured from 100% virgin high-density polyethylene with density 0.94-0.97 g/cm³, ensuring near-neutral buoyancy for easy fluidization with minimal aeration energy.
• Rapid Biofilm Colonization: Optimized surface roughness and hydrophilicity accelerate initial bacterial attachment, achieving full biofilm maturation in 2-4 weeks under typical municipal conditions.
• Wide Temperature Range: Stable performance from 5°C to 65°C, suitable for tropical Latin American climates as well as high-altitude Andean treatment plants.
• 15+ Year Service Life: UV-stabilized and chemical-resistant HDPE formulation resists degradation from chlorine, acids, and alkalis commonly encountered in wastewater treatment.
