  • 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. desander removes the abrasive solids from.

  • silt fence

    sand and silt tends to clog the fabric, and then the sediments settle in the temporary pond.: p.6–9: p.7–46. super silt fence. some government jurisdictions in the united states recommend or require the use of a reinforced fence, sometimes called a 'super' silt fence or an enhanced silt fence, on some construction sites.

  • wastewater

    wastewater or waste water is any water that has been contaminated by human use. wastewater is 'used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration'. therefore, wastewater is a byproduct of domestic, industrial, commercial or agricultural activities.

  • culvert

    a culvert is a structure that allows water to flow under a road, railroad, trail, or similar obstruction from one side to the other. typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material. in the united kingdom, the word can also be used for a longer artificially buried watercourse. .

  • tailings

    during extraction of the oil from oil sand, tailings consisting of water, silt, clays and other solvents are also created. this solid will become mature fine tailings by gravity. foght et al 1985 estimated that there are 10 3 anaerobic heterotrophs and 10 4 sulfate-reducing prokaryotes per milliliter in the tailings pond, based on conventional most probable number methods.

  • septic drain field

    coarse soils – sand and gravel – can transmit wastewater away from the drain field before pathogens are destroyed. silt and clay effectively filter out pathogens but allow very limited wastewater flow rates. percolation tests measure the rate at which clean water disperses through a disposal trench into the soil.

  • sump

    a sump american english and some parts of canada: oil pan is a low space that collects often undesirable liquids such as water or chemicals.a sump can also be an infiltration basin used to manage surface runoff water and recharge underground aquifers. sump can also refer to an area in a cave where an underground flow of water exits the cave into the earth.

  • soil liquefaction

    quicksand forms when water saturates an area of loose sand and the sand is agitated. when the water trapped in the batch of sand cannot escape, it creates liquefied soil that can no longer resist force. quicksand can be formed by standing or upwards flowing underground water as from an underground spring , or by earthquakes.

  • sand separator

    a sand separator is a device that separates sand or other solids from water. one version of sand separator utilizes centrifugal force to separate sand or other heavy particles out of the water. the separated material drops down into a tank or reservoir where it can be removed later or in the case of in-well separators, the separated sand drops into the bottom of the well .

  • manhole

    in australia, manhole also commonly refers to an access hatch used to get access from a room or hallway into the ceiling cavity of a building. these manholes are typically around 450 mm square.
