  2. Effluent - Wikipedia

    en.wikipedia.org/wiki/Effluent

    An effluent sump pump, for instance, pumps waste from toilets installed below a main sewage line. In the context of waste water treatment plants, effluent that has been treated is sometimes called secondary effluent, or treated effluent. This cleaner effluent is then used to feed the bacteria in biofilters. [8]

  3. Effluent sewer - Wikipedia

    en.wikipedia.org/wiki/Effluent_sewer

    Effluent pumping sewers have small diameter pipes that follow the contour of the land and are only buried a metre or two underground. While an effluent sewer can use gravity to move waste, the ability to move waste with a pressure system can be a big advantage in places where a gravity system is impractical.

  4. Industrial wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_wastewater...

    Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.

    It thus converts it into an effluent that can be returned to the water cycle. 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.

  6. Sewage treatment - Wikipedia

    en.wikipedia.org/wiki/Sewage_treatment

    Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. [2]

  7. Septic drain field - Wikipedia

    en.wikipedia.org/wiki/Septic_drain_field

    A drain field may be designed to offer several separate disposal areas for effluent from a single septic tank. One area may be "rested" while effluent is routed to a different area. The nematode community in the resting drain field continues feeding on the accumulated biofilm and fats when the anaerobic septic tank effluent is no longer available.

  8. Effluent guidelines - Wikipedia

    en.wikipedia.org/wiki/Effluent_guidelines

    The United States Environmental Protection Agency (EPA) issues Effluent Guideline regulations for categories of industrial sources of water pollution under Title III of the Clean Water Act (CWA). [1] The standards are technology-based, i.e. they are based on the performance of treatment and control technologies (e.g., Best Available Technology ...

  9. Wastewater - Wikipedia

    en.wikipedia.org/wiki/Wastewater

    Wastewater (or waste water) is water generated after the use of freshwater, raw water, drinking water or saline water in a variety of deliberate applications or processes. [1]: 1 Another definition of wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration".
