  2. Moving bed biofilm reactor - Wikipedia

    en.wikipedia.org/wiki/Moving_Bed_Biofilm_Reactor

    Moving bed biofilm reactors can efficiently treat hospital wastewater and remove pharmaceutical micropollutants. A 2023 study has shown that a strictly anaerobic MBBR, combined with an aerobic biofilm reactor can achieve high removal rates of pharmaceuticals, such as metronidazole, trimethoprim, sulfamethoxazole, and valsartan.

  3. Application of biofilms in industry - Wikipedia

    en.wikipedia.org/wiki/Application_of_biofilms_in...

    While membrane bioreactors filter out flocs in activated sludge, membrane biofilm reactors feed gas —such as O 2, H 2, and CH 4 —to promote biofilm growth on the surface of hydrophobic membranes. The biofilm grows on a fixed surface rather than in a suspension. These reactors have the potential to efficiently remove micropollutants from ...

  4. Bioreactor - Wikipedia

    en.wikipedia.org/wiki/Bioreactor

    [4] [5] Immobilization is useful for continuously operated processes, since the organisms will not be removed with the reactor effluent, but is limited in scale because the microbes are only present on the surfaces of the vessel. Large scale immobilized cell bioreactors are: moving media, also known as moving bed biofilm reactor (MBBR) packed bed

  5. Bruce Rittmann - Wikipedia

    en.wikipedia.org/wiki/Bruce_Rittmann

    Membrane biofilm reactors [ edit ] Rittmann is the inventor of the Hydrogen -based Membrane Biofilm Reactor (MBfR), [ 3 ] which can be used to reduce and detoxify a wide range of oxidized pollutants commonly found in water: e.g., nitrate , perchlorate , chromate , selenate , trichloroethene , and uranyl .

  6. Secondary treatment - Wikipedia

    en.wikipedia.org/wiki/Secondary_treatment

    Fixed-film or attached growth secondary treatment bioreactors are similar to a plug flow reactor model circulating water over surfaces colonized by biofilm, while suspended-growth bioreactors resemble a continuous stirred-tank reactor keeping microorganisms suspended while water is being treated. Secondary treatment bioreactors may be followed ...

  7. Rotating biological contactor - Wikipedia

    en.wikipedia.org/wiki/Rotating_biological_contactor

    Biofilms, which are biological growths that become attached to the discs, assimilate the organic materials (measured as BOD5) in the wastewater. Aeration is provided by the rotating action, which exposes the media to the air after contacting them with the wastewater, facilitating the degradation of the pollutants being removed.

  9. Anammox - Wikipedia

    en.wikipedia.org/wiki/Anammox

    For the enrichment of the anammox organisms a granular biomass or biofilm system seems to be especially suited in which the necessary sludge age of more than 20 days can be ensured. Possible reactors are sequencing batch reactors (SBR), moving bed reactors or gas-lift-loop reactors. The cost reduction compared to conventional nitrogen removal ...
