MBBR Polyurethane Biofilter Media K1 K3 K5

MBBR polyurethane K1/K3/K5 biofilter media enhances treatment efficiency and reduces sludge return for Sewage Treatment Equipment by promoting rapid biofilm growth and high contaminant degradation. Manufactured as hydrophilic porous polyurethane pellets (10 ± 1 mm after expansion) with >2000 m2/m3 specific surface area, 98% voidage and ~12.5 kg/m3 dry density, it ensures fast microbial attachment, excellent BOD/COD/NH3 removal and a service life beyond 10 years. Packaged in standard export cartons with 3–20 day delivery windows and easy retrofit compatibility, this wear‑resistant media lowers energy and maintenance costs while simplifying installation and handling.

High Surface Area Media

The MBBR polyurethane biofilter media (K1, K3, K5) is a hydrophilic porous gel carrier with a unique wall structure, >2000 m2/m3 specific surface area, ~98% voidage and high elasticity that promotes durable microbial attachment and a service life beyond 10 years. In Sewage Treatment Equipment it functions as a fluidized aerobic carrier where rapid biofilm formation and mass transfer enable high nitrification and BOD/COD oxidation rates while reducing fan energy and sludge return. With wide pH and temperature tolerance, easy integration into MBBR systems, and high biological attachment density, the media delivers efficient contaminant removal, lower operating costs and stable, low‑maintenance performance for municipal and industrial wastewater treatment.

The K1/K3/K5 MBBR polyurethane biofilter media is a hydrophilic porous PPC carrier with a unique wall structure that provides a very high specific surface area (>2000 m2/m3), excellent elasticity, and long service life to support aerobic biofilm growth. Kept fluidized by aeration, the carriers promote rapid microbial attachment and efficient pollutant removal with high nitrification and BOD/COD oxidation capacities while reducing sludge return and fan energy consumption. Suitable for MBBR systems, municipal and industrial wastewater treatment, and integrated Sewage Treatment Equipment, these carriers work across a wide pH and temperature range and last more than 10 years.
