  2. Maceration (sewage) - Wikipedia

    en.wikipedia.org/wiki/Maceration_(sewage)

    Maceration can be achieved by using a chopper pump in the sewage lift station or at the wastewater treatment plant. [1] When the flush is triggered, wastewater flows into the macerator, and when the water level rises, pressure activates the unit, causing the stainless steel blades to rotate at 3,600 rpm, pulverizing the wastewater into fine ...

    en.wikipedia.org/wiki/Onsite_sewage_facility

    Post-tank treatment can include aerobic (with oxygen) or anaerobic (with no or low oxygen) biological treatment in suspended or fixed-film reactors, physical/chemical treatment, soil infiltration, fixed-media filtration, and/or disinfection. The application and sizing of treatment units based on these technologies are defined by performance ...

  4. 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.

  5. 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]

  6. Vacuum sewer - Wikipedia

    en.wikipedia.org/wiki/Vacuum_sewer

    Once the wastewater arrives in the vacuum collection tank at the vacuum station, it is pumped to the discharge point, which could be either a gravity sewer or the treatment station. As the dwell time of the wastewater inside the system is very short and the wastewater is continuously mixed with air, the sewage is kept fresh and any fouling ...

  7. Grinder pump - Wikipedia

    en.wikipedia.org/wiki/Grinder_pump

    The grinder pump “station” consists of the pump, a tank, and an alarm panel. A pump for household use is usually 1 hp, 1.5 hp or 2 hp. A cutting mechanism macerates waste and grinds items that are not normally found in sewage, but may get flushed down the toilet. The pump has a level sensor either built into the pump, called “sensing ...
