sedimentation is a physical water treatment process using gravity to remove suspended solids from water. solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation.
the rapid sand filter or rapid gravity filter is a type of filter used in water purification and is commonly used in municipal drinking water facilities as part of a multiple-stage treatment system.. rapid sand filters were first developed in the 1890s, and improved designs were developed by the 1920s. the first modern rapid sand filtration plant was designed and built by george w. fuller in .
a pallet jack, also known as a pallet truck, pallet pump, pump truck, scooter, dog, or jigger is a tool used to lift and move pallets.pallet jacks are the most basic form of a forklift and are intended to move pallets within a warehouse.
thin layer extraction is a time-periodic reactive liquid extraction process that provides excellent mass transfer while maintaining phase separation. it is performed via a periodic batch production process that controls the time of each chemical reaction
electroextraction ee is a sample enrichment technique that focuses charged analytes from a large volume of one phase into a small volume of aqueous phase through the application of an electric current. the technique was originally developed as a separation technique for chemical engineering, but has since been coupled to capillary electrophoresis and liquid chromatography–mass spectrometry .
gravity plate separator a gravity plate separator contains a series of plates through which the contaminated water flows. the objective of the design is to allow oil droplets in the water to coalesce on the underside of the plate eventually forming larger oil droplets which floats off the plates and accumulates at the top of the chamber.
this glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields.astronomy is concerned with the study of celestial objects and phenomena that originate outside the atmosphere of earth.the field of astronomy features an extensive vocabulary and a significant amount of jargon.
an oily water separator ows marine is a piece of equipment specific to the shipping or marine industry.it is used to separate oil and water mixtures into their separate components. this page refers exclusively to oily water separators aboard marine vessels.
the water can be separated from the oil in a three-phase separator by use of chemicals and gravity separation. if the three-phase separator is not large enough to separate the water adequately, it can be separated in a free-water knockout vessel installed upstream or downstream of the separators. secondary functions of oil and gas separators
the equipment is a separate flow-through electrostatic treatment section installed upstream of a gravity separator to improve the performance. by keeping the treatment and settling sections separate, a compact electrostatic coalescer can be obtained that can also be retrofitted.
