Description
The DC PU foam MBBR media is a high-performance, industry-standard biofilm carrier designed to optimize biological treatment efficiency in water and wastewater management systems. Fabricated from premium polyurethane (PU) and engineered into a uniform cubic shape, this carrier is purpose-built for deployment in Moving Bed Biofilm Reactor (MBBR) systems, where it serves as a stable, protected substrate for microbial colonization and proliferation.
With a specific surface area exceeding 1200 m²/m³ and a precisely controlled pore size of 20–25 ppi, the media provides an expansive and sheltered internal environment that supports robust biofilm formation. This protected pore structure is a key technical advantage: it shields the immobilized microorganisms from hydrodynamic shear forces and mechanical agitation, minimizing biofilm detachment and ensuring stable biomass retention even under dynamic operational conditions. The material’s mechanical properties—including a tensile strength of 0.05 Mpa, tear strength of 1.8 N/cm, and rebound coefficient of 25%—further enhance its durability, enabling long-term resistance to wear and deformation within continuous-flow systems.
The carrier’s optimized density of 0.95±0.02 g/cm³ ensures ideal fluidization in MBBR reactors, promoting uniform mixing and consistent contact between the biofilm and wastewater. This, combined with a service life of over 15 years and reliable performance across an operating temperature range of 5–60°C, delivers sustained biological treatment efficiency, reduces operational downtime, and lowers lifecycle costs. By facilitating the stable growth of pollutant-degrading biofilms, the DC PU foam MBBR media plays a critical role in enhancing the removal of organic matter, nitrogen, and other contaminants, making it a dependable choice for advanced water treatment infrastructure.
