  2. Silt fence - Wikipedia

    en.wikipedia.org/wiki/Silt_fence

    A silt fence, sometimes (misleadingly) called a "filter fence," [ 1 ] is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in stormwater runoff. Silt fences are widely used on construction sites in North America and elsewhere, due to their ...

  3. Airlift pump - Wikipedia

    en.wikipedia.org/wiki/Airlift_pump

    G: Gravel or solids. An airlift pump is a pump that has low suction and moderate discharge of liquid and entrained solids. The pump injects compressed air at the bottom of the discharge pipe which is immersed in the liquid. The compressed air mixes with the liquid causing the air-water mixture to be less dense than the rest of the liquid around ...

  4. Desander - Wikipedia

    en.wikipedia.org/wiki/Desander

    Desander. Desanders and desilters are solid control equipment with a set of hydrocyclones that separate sand and silt from the drilling fluids in drilling rigs. Desanders are installed on top of the mud tank following the shale shaker and the degasser, but before the desilter. The desander removes the abrasive solids from the drilling fluids ...

    Pumps being used to dewater a spillway at Baldhill Dam. Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from a location. This may be done by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.

  8. Sedimentation (water treatment) - Wikipedia

    en.wikipedia.org/wiki/Sedimentation_(water...

    The physical process of sedimentation (the act of depositing sediment) has applications in water treatment, whereby gravity acts to remove suspended solids from water. [ 1 ] Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans.

  9. Settling basin - Wikipedia

    en.wikipedia.org/wiki/Settling_basin

    A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater. The basins are used to control water pollution in diverse industries such as agriculture, [1] aquaculture, [2] and mining. [3][4] Turbidity is an optical property of water caused by ...
