Warden Biomedia

- Model Biotube - Tube Shaped Biological Filter Media


Spoke design biological filter media with internal and external fins and surface area of 1000m²/m³. The Biotube is designed to provide a large protected surface area for the biofilm and optimal conditions for the bacteria culture when the media are suspended in water. A durable, rugged and highly efficient media for moving bed biological reactors (MBBR) and integrated fixed film activated sludge (IFAS) systems.

Its innovative design creates a high percentage of protected surface area for microorganisms to adhere. In turn, this increases the overall biomass concentration and can reduce the tank volume required for wastewater treatment. Large openings allow for the wastewater to freely pass through the media which helps maintain a healthy and thin biofilm.

Warden's biological filter media is feasible for both industrial and municipal wastewater and is used for organic removal, nitrification and denitrification.
