The Advance MBBR Media Model PP 1225 is an engineered bio filter media designed specifically for Moving Bed Biofilm Reactor (MBBR) wastewater treatment systems. Made from virgin HDPE/PE material with UV stabilization, this bio media offers exceptional durability and longevity with a lifespan exceeding 20 years. The media features a cylindrical structure with external fins, 19 holes per unit, a diameter of 25 mm, and a height of 12 mm, optimizing surface area and biofilm growth. With an effective specific surface area of 500 m²/m³, the media ensures superior biofilm adhesion and microbial activity for efficient organic load removal. It is characterized by high voidage (>97%) and a PSA/TSA ratio of over 90%, facilitating ideal oxygen transfer and biomass retention. Operating effectively within a temperature range of 5-45°C, the media supports a BOD5 loading of 1500-2000 g/m³/day and COD loading of 2000-15000 g/m³/day. The low specific gravity (0.90–0.95 g/cm³) allows excellent hydraulic movement and contact within the reactor. This advanced MBBR media is essential for advanced wastewater treatment plants seeking robust, long-lasting, and highly efficient biofilm carriers to enhance microbial degradation and biomass retention in diverse industrial and municipal applications.

The media is designed to operate continuously at temperatures ranging from 5°C to 45°C, ensuring reliable performance in various wastewater conditions.
With a PSA/TSA ratio over 90%, the media offers an optimal proportion of protected specific area (PSA) to total specific area (TSA), facilitating better biofilm protection and enhanced microbial activity for efficient organic matter breakdown.
The media fill rate ranges from 25% to 55% of the reactor volume, which balances media movement with biofilm density for optimum treatment efficiency.
Biofilm membrane formation typically occurs within 3 to 15 days after initiation, enabling quick start-up and effective biomass development.
Constructed from virgin HDPE with UV stabilization, the media has a lifespan of over 20 years under normal operating conditions, ensuring long-term reliability and minimal replacement costs.
