  2. Extended aeration - Wikipedia

    en.wikipedia.org/wiki/Extended_aeration

    Extended aeration agitates all incoming waste in the sludge from a single clarifier. The combined sludge starts with a higher concentration of inert solids than typical secondary sludge and the longer mixing time required for digestion of primary solids in addition to dissolved organics produces aged sludge requiring greater mixing energy input per unit of waste oxidized.

  3. Fecal sludge management - Wikipedia

    en.wikipedia.org/wiki/Fecal_sludge_management

    Septage is periodically removed (with a frequency depending on tank capacity, system efficiency, and usage level, but typically less often than annually) from the septic tanks by specialized vehicles known as vacuum trucks. They pump the septage out of the tank, and transport it to a local fecal sludge treatment plant.

  4. Septic tank - Wikipedia

    en.wikipedia.org/wiki/Septic_tank

    A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]

  5. Onsite sewage facility - Wikipedia

    en.wikipedia.org/wiki/Onsite_sewage_facility

    A septic tank being installed. The next step is to plug it to the intake and outtake pipes and backfill it with soil. Engineered facilities that use water suspension to transport solids (private septic systems and municipal facilities) typically form a floating layer in their primary settling tank, consisting of low-density liquids such as oils ...

  6. Effluent sewer - Wikipedia

    en.wikipedia.org/wiki/Effluent_sewer

    If there is a suitable septic tank in place, pumping the effluent from the tank is the lowest cost option for initial costs. Whether the septic tank is the lowest cost option over time depends on the cost of electricity in the area, how often the tank must be emptied and how much it costs to have the solids pumped out of the tank.

  7. Sewage sludge treatment - Wikipedia

    en.wikipedia.org/wiki/Sewage_sludge_treatment

    "Biosolids" is a term often used in wastewater engineering publications and public relations efforts by local water authorities when they want to put the focus on reuse of sewage [7] sludge, after the sludge has undergone suitable treatment processes.
