LEVAPOR is a biological carrier used in Moving Bed Biofilm Reactors (MBBR) and Integrated Fixed-Film Activated Sludge (IFAS) systems.
It is a hydrophilic reticulated polyurethane (PU) foam impregnated with activated carbon. The foam provides a very large surface area, and the activated carbon improves adsorption of toxic or inhibitory compounds.
Microorganisms attach to the carrier and form a biofilm, enabling efficient biological treatment (e.g., reduction of BOD, COD, nitrification, denitrification) with higher performance and better stability than conventional suspended biomass systems.

Key Technical Properties
-
Very high specific surface area: In some references, >20,000 m²/m³, far higher than standard plastic carriers.
-
Porous internal structure: Typical pore size 450–750 µm, promoting biofilm growth and protecting biomass.
-
Activated carbon impregnation: Allows temporary adsorption of toxic shocks before biological degradation, increasing robustness.
-
Fast wetting and high hydrophilicity: Promotes rapid microbial colonization.
-
Low reactor filling ratio: Typically 10–15% thanks to the high surface area, reducing reactor volume or increasing treatment capacity.
Advantages
-
Higher biological efficiency: more active attached biomass, stronger nitrification/denitrification.
-
High stability against load variations or toxicity due to adsorption and biofilm protection.
-
Reduced sludge production compared to suspended biomass systems.
-
Useful for upgrading existing wastewater treatment installations.
Applications
-
Aquaculture systems, especially RAS (Recirculating Aquaculture Systems).
-
Upgrading activated sludge, SBR, MBBR, IFAS systems.
