  2. Membrane bioreactor - Wikipedia

    en.wikipedia.org/wiki/Membrane_bioreactor

    Membrane bioreactors are combinations of membrane processes like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. These technologies are now widely used for municipal and industrial wastewater treatment. [1] The two basic membrane bioreactor configurations are the submerged ...

  3. Membrane reactor - Wikipedia

    en.wikipedia.org/wiki/Membrane_reactor

    A membrane reactor is a physical device that combines a chemical conversion process with a membrane separation process to add reactants or remove products of the reaction. [ 1 ] Chemical reactors making use of membranes are usually referred to as membrane reactors. The membrane can be used for different tasks: [ 2 ] Separation.

  4. Secondary treatment - Wikipedia

    en.wikipedia.org/wiki/Secondary_treatment

    Membrane bioreactors (MBR) are activated sludge systems using a membrane liquid-solid phase separation process. The membrane component uses low pressure microfiltration or ultrafiltration membranes and eliminates the need for a secondary clarifier or filtration. The membranes are typically immersed in the aeration tank; however, some ...

  5. Bioreactor - Wikipedia

    en.wikipedia.org/wiki/Bioreactor

    Bioreactor. A bioreactor is any manufactured device or system that supports a biologically active environment. [ 1 ] In one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms. This process can either be aerobic or anaerobic.

  6. Anaerobic membrane bioreactor - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_membrane_bioreactor

    Anaerobic membrane bioreactor or AnMBR is the name of a technology utilized in wastewater treatment. It is a technology in membrane filtration for biomass retention. AnMBR works by using a membrane bioreactor (MBR) in a anaerobic environment. Anaerobic bacteria ( Mesophile or Thermophile) and archaea convert organic materials into carbon ...

  7. Hollow fiber bioreactor - Wikipedia

    en.wikipedia.org/wiki/Hollow_fiber_bioreactor

    From Wikipedia, the free encyclopedia. A Hollow fiber bioreactoris a 3 dimensional cell culturingsystem based on hollow fibers, which are small, semi-permeable capillarymembranesarranged in parallel array with a typical molecular weightcut-off (MWCO) range of 10-30 kDa. These hollow fiber membranesare often bundled and housed within tubular ...

  8. Moving bed biofilm reactor - Wikipedia

    en.wikipedia.org/wiki/Moving_Bed_Biofilm_Reactor

    Moving bed biofilm reactor. Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process that was first invented by Professor Hallvard Ødegaard at Norwegian University of Science and Technology in the late 1980s. [1] The process takes place in an aeration tank with plastic carriers that a biofilm can grow on.

  9. Membrane technology - Wikipedia

    en.wikipedia.org/wiki/Membrane_technology

    Membrane technology encompasses the scientific processes used in the construction and application of membranes. Membranes are used to facilitate the transport or rejection of substances between mediums, and the mechanical separation of gas and liquid streams. In the simplest case, filtration is achieved when the pores of the membrane are ...
