    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.

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

    In moving-bed biofilm reactors, biofilms grow on small plastic or sponge-based carriers that circulate in the bioreactors using aeration or mechanical stirring. This allows for high contact between contaminants in the wastewater and adding more carriers can increase the rate of biodegradation .

    [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

  7. Fluidized bed reactor - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_reactor

    A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

  8. 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 ...

  9. Packed bed - Wikipedia

    en.wikipedia.org/wiki/Packed_bed

    Packed bed reactors are reactor vessels containing a fixed bed of catalytic material, they are widely used in the chemical process industry and find primary use in heterogeneous, gas-phase, catalytic reactions. The advantages of using a packed bed reactor include the high conversion of reactants per unit mass of catalyst, relatively low ...
