    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 ...

    Most onsite wastewater treatment systems are of the conventional type, consisting of a septic tank and a subsurface wastewater infiltration system (SWIS). Site limitations and more stringent performance requirements have led to significant improvements in the design of wastewater treatment systems and how they are managed.

    Typically, waste is pumped uphill under low pressure to the main sewer line in such situations, either after it has been through a septic tank or after it has been ground up into a slurry by a grinder. Grinding can be done when the waste of many homes or businesses is combined or smaller grinders can be installed at each home or business.

  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]

    The discs consist of plastic sheets ranging from 2 to 4 m in diameter and are up to 10 mm thick. Several modules may be arranged in parallel and/or in series to meet the flow and treatment requirements. The discs are submerged in waste water to about 40% of their diameter.

  7. 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.
