  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. 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.

  4. Rotating biological contactor - Wikipedia

    en.wikipedia.org/wiki/Rotating_biological_contactor

    A rotating biological contactor is a type of secondary (biological) treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the wastewater. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes ...

  5. Activated sludge - Wikipedia

    en.wikipedia.org/wiki/Activated_sludge

    Activated sludge. Activated sludge tank at Beckton sewage treatment plant, UK. The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.

  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. Enhanced biological phosphorus removal - Wikipedia

    en.wikipedia.org/wiki/Enhanced_biological...

    Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. [1] The common element in EBPR implementations is the presence of an anaerobic tank ( nitrate and oxygen are absent) prior to the aeration tank. Under these conditions a group of heterotrophic ...

  8. Secondary treatment - Wikipedia

    en.wikipedia.org/wiki/Secondary_treatment

    Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [1] : 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.
