  2. Metabolic waste - Wikipedia

    en.wikipedia.org/wiki/Metabolic_waste

    It is a very toxic substance to tissues and extremely soluble in water. Only one nitrogen atom is removed with it. A lot of water is needed for the excretion of ammonia, about 0.5 L of water is needed per 1 g of nitrogen to maintain ammonia levels in the excretory fluid below the level in body fluids to prevent toxicity.

  3. Reuse of human excreta - Wikipedia

    en.wikipedia.org/wiki/Reuse_of_human_excreta

    This also applies to excreta-based fertilizer since it also contains nitrogen. Excessive nitrogen which is not taken up by plants is transformed into nitrate which is easily leached. [47] High application rates combined with the high water-solubility of nitrate leads to increased runoff into surface water as well as leaching into groundwater.

  4. Anaerobic lagoon - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_lagoon

    In order to manage their waste, CAFOs have developed agricultural wastewater treatment plans. To save on manual labor, many CAFOs handle manure waste as a liquid. [7] In this system, the animals are kept in pens with grated floors so the waste and spray water can be drained from underfloor gutters and piped to storage tanks or anaerobic lagoons ...

  5. Nitrogen cycle - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_cycle

    The nitrogen cycle is an important process in the ocean as well. While the overall cycle is similar, there are different players [40] and modes of transfer for nitrogen in the ocean. Nitrogen enters the water through the precipitation, runoff, or as N 2 from the atmosphere. Nitrogen cannot be utilized by phytoplankton as N

  6. Anammox for wastewater treatment - Wikipedia

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

    The struvite crystals contain nutrients essential to plant growth that are easy to use and transport. This process also helps to recover nitrogen and phosphorus from wastewater, [9] helping to improve surface water quality as these are two of the primary elements that can cause eutrophication. If eutrophication occurs, an anammox cycle can take ...

  7. Fecal sludge management - Wikipedia

    en.wikipedia.org/wiki/Fecal_sludge_management

    Fecal sludge is defined very broadly as what accumulates in onsite sanitation technologies and specifically is not transported through a sewer.It is composed of human excreta, but also anything else that may go into an onsite containment technology, such as flushwater, cleansing materials and menstrual hygiene products, grey water (i.e. bathing or kitchen water, including fats, oils and grease ...

  8. Agricultural wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Agricultural_wastewater...

    Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...

  9. 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 ...
