    Features & Benefits

    • Smallest Footprint – saves on expensive space.

    • Lowest operating cost- Due to higher oxygen transfers, the total air requirement is lesser

    • Modular Expansion - The MBBR system allows gradual, multi-step, plant expansion, by gradual addition of biomass carriers.

    • More Stable Process - Toxic upsets and hydraulic 'wash out' events never affect the entire microbial population in the bio-film, thus process   recovery is fast and smooth.

    • Intensive Nitrification - The MBBR system enables quantitative nitrification even at a low sludge age of the activated sludge, by holding a       separate population on the biomass carriers.

    • Low Temperature Nitrification - A biofilm rich with autotrophs allows stable nitrification even at low temperatures.

    • Better Sludge Quality - Nitrification in the MBBR system occurs at low suspended-sludge age, resulting in better sludge settling properties.


    • Higher oxygen transfer; reduced operating cost due to smaller blower

    • Reduced maintenance; elimination of plugging; reduced cost

    • Allows for expansion / upgrade without additional increasing tank volume

    • Nitrogen removal without increased hydraulic retention time

    • Shock proof system: Fixed-film biomass is attached to carriers designed to remain in the aeration basin even under hydraulic upset               conditions; due to biofilm layers on the media, toxic upsets typically do not affect all active biomass and recovery is much quicker than with   suspended growth systems.
