  2. Waste management - Wikipedia

    en.wikipedia.org/wiki/Waste_management

    Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. [1] This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.

  3. Clarifier - Wikipedia

    en.wikipedia.org/wiki/Clarifier

    To further discourage the overt mixing within the clarifier and increase the retention time allowed for the particles to settle, the inlet flow should also be distributed evenly across the entire cross section of the settling zone inside the clarifier, where the volume is maintained at 37.7 percent capacity.

  4. Effluent - Wikipedia

    en.wikipedia.org/wiki/Effluent

    Wastewater percolated or injected into groundwater may not be described as effluent if soil is assumed to perform treatment by filtration or ion exchange; [4] although concealed flow through fractured bedrock, lava tubes, limestone caves, [5] or gravel in ancient stream channels [6] may allow relatively untreated wastewater to emerge as springs ...

  5. Rotating biological contactor - Wikipedia

    en.wikipedia.org/wiki/Rotating_biological_contactor

    The shaft is aligned with the flow of wastewater so that the discs rotate at right angles to the flow, with several packs usually combined to make up a treatment train. About 40% of the disc area is immersed in the wastewater. [8]: Ch 2 Biological growth is attached to the surface of the disc and forms a slime layer.

  6. Wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Wastewater_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. [5]

  8. Flow control structure - Wikipedia

    en.wikipedia.org/wiki/Flow_control_structure

    A flow control structure is a device that alters the flow of water in a stream, drainage channel or pipe. As a group these are passive structures since they operate without intervention under different amounts of water flow and their impact changes based on the quantity of water available.

  9. Waste minimisation - Wikipedia

    en.wikipedia.org/wiki/Waste_minimisation

    Management and control measures at hospital level. Centralized purchasing of hazardous chemicals. Monitoring the flow of chemicals within the health care facility from receipt as a raw material to disposal as a hazardous waste. The careful separation of waste matter to help minimise the quantities of hazardous waste and disposal.
