MBBR Fluidized Bed Bio Media (K1/K2/K3) – For Sewage Treatment & Aquarium Filters
Our company's biological media is a high-performance polymeric plastic biofilm carrier, scientifically designed and manufactured through a proprietary process. With a specific gravity of 0.97—slightly less than water—it becomes neutrally buoyant as biofilm develops, allowing it to remain suspended and freely moving within the treatment system.
This filler offers an exceptionally high surface area of over 500 m²/m³, providing ample space for microbial colonization. Although microorganisms grow attached to the media, the carriers fluidize like activated sludge, ensuring optimal contact and efficient treatment. Under suitable conditions, the volumetric load can reach up to 35 kg COD/m³·day.
The unique structural design enhances air retention in water, improving oxygen transfer efficiency, reducing energy consumption, and delivering direct economic benefits.
Key Features:
Easy to Use: Direct dosing without fixation; free-moving in aeration tanks or fish tanks with no dead zones.
Quick Biofilm Formation: High biofilm activity, resistant to clogging, no backwashing needed, and no sludge return required.
Durable & Long-Lasting: Made of stable polymer material for extended service life.
High Surface Area, Low Pressure Loss: Maximizes microbial growth while minimizing flow resistance.
Easy Installation & Maintenance: Simplified design for effortless setup, upkeep, and replacement.
Energy-Saving: High oxygen transfer efficiency reduces operational costs.
Broad Compatibility: Effective in aerobic, anoxic, and anaerobic environments.
Nutrient Removal: Supports nitrogen and phosphorus removal processes.
Strong Adaptability: Handles high organic and impact loads with operational flexibility.
