  2. Newtown Creek Wastewater Treatment Plant - Wikipedia

    The egg-shaped structures house the plant's sludge digesters. The digesters use a process called anaerobic digestion to transform the sewage plant sludge byproduct into a form which can be used as fertilizer. [7] The plant gives monthly public tours of the digester eggs, for which reservations are required.

  3. Wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Wastewater_treatment

    Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it. This process is called water reclamation. [1] The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant.

  4. Waste stabilization pond - Wikipedia

    en.wikipedia.org/wiki/Waste_stabilization_pond

    After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water) if the effluent meets the required effluent standards (e.g. sufficiently low levels of pathogens). Waste stabilization ponds involve natural treatment processes which take time because removal rates are slow.

  5. Secondary treatment - Wikipedia

    en.wikipedia.org/wiki/Secondary_treatment

    The purpose of tertiary treatment (also called advanced treatment) is to provide a final treatment stage to further improve the effluent quality before it is discharged to the receiving water body or reused. More than one tertiary treatment process may be used at any treatment plant. If disinfection is practiced, it is always the final process.

  6. Dissolved air flotation - Wikipedia

    en.wikipedia.org/wiki/Dissolved_air_flotation

    Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms ...

    Instead, the surrounding water assumes the role of the eggshell, exerting enough inward pressure on the egg (2.8 times atmospheric pressure, to be exact) to keep it intact.

  9. Mixed liquor suspended solids - Wikipedia

    en.wikipedia.org/wiki/Mixed_liquor_suspended_solids

    Mixed liquor suspended solids (MLSS) is the concentration of suspended solids, in an aeration tank during the activated sludge process, which occurs during the treatment of waste water. The units MLSS is primarily measured in milligram per litre (mg/L), but for activated sludge its mostly measured in gram per litre [g/L] which is equal to ...
