  2. SHARON Wastewater Treatment - Wikipedia

    en.wikipedia.org/wiki/SHARON_Wastewater_Treatment

    The SHARON (Single reactor system for High activity Ammonium Removal Over Nitrite) wastewater treatment process is a combination of two already used nitrogen removing reactions. One process utilizes fast growing nitrifiers utilizing nitrification of ammonia to nitrite and Anammox which is the denitrification of nitrite to atmospheric nitrogen ...

  3. Nitrification - Wikipedia

    en.wikipedia.org/wiki/Nitrification

    Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. ... but most wastewater treatment plants discharge to surface water.

  4. Comammox - Wikipedia

    en.wikipedia.org/wiki/Comammox

    Comammox have been found in many engineered systems including aquaculture biofiltration units, drinking water treatment and distribution systems, and wastewater treatment plants. [ 3 ] [ 6 ] The growth of comammox in these engineered ecosystems co-occur with ammonia-oxidizing bacteria and/or archaea, and in some cases outnumber other ammonia ...

  5. Rotating biological contactor - Wikipedia

    en.wikipedia.org/wiki/Rotating_biological_contactor

    The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.

  6. Nitrifying bacteria - Wikipedia

    en.wikipedia.org/wiki/Nitrifying_bacteria

    [12] [13] Complete nitrification, the conversion of ammonia to nitrate in a single step known as comammox, has an energy yield (∆G°′) of −349 kJ mol −1 NH 3, while the energy yields for the ammonia-oxidation and nitrite-oxidation steps of the observed two-step reaction are −275 kJ mol −1 NH 3, and −74 kJ mol −1 NO 2 − ...

  7. Simultaneous nitrification–denitrification - Wikipedia

    en.wikipedia.org/wiki/Simultaneous_nitrification...

    Simultaneous nitrification–denitrification (SNdN) is a wastewater treatment process. Microbial simultaneous nitrification - denitrification is the conversion of the ammonium ion to nitrogen gas in a single bioreactor .

  8. Anammox for wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Anammox_for_wastewater...

    The two main chemicals needed for the metabolism of anammox bacteria to function are ammonia and nitrite. Nitrate and nitrite are produced by microorganisms within wastewater treatment facilities as a result of sewage treatment. The chemical compound ammonia monooxygenase converts ammonia in wastewater into nitrite during the nitrification process.

  9. Anammox - Wikipedia

    en.wikipedia.org/wiki/Anammox

    The application of the anammox process lies in the removal of ammonium in the wastewater treatment and consists of two separate processes. The first step is the partial nitrification (nitritation) of half of the ammonium to nitrite by ammonia oxidizing bacteria: 2 NH + 4 + 3 O 2 → 2 NO − 2 + 4 H + + 2 H 2 O
