English term or phrase: air sparging
Definition from United States Department of Agriculture:
Air sparging is an in situ remedial technology that reduces concentrations of volatile constituents in petroleum products that are adsorbed to soils and dissolved in groundwater. It involves the injection of contaminant-free air into the subsurface saturated zone, enabling a phase transfer of hydrocarbons from a dissolved state to a vapor phase. The air is then vented through the unsaturated zone.

Example sentence(s):
  • The air sparging system is incorporated as an annular header surrounding a portion of the body of the hydrocyclone with a porous wall providing the necessary passageway for air dispersion into the hydrocyclone. Free Patents Online
  • An air sparging system can use either vertical or horizontal sparge wells. Well orientation should be based on site-specific needs and conditions. United States EPA
  • From the latter we can estimate the maximum radius of influence of air sparging, as a function of the physical parameters. ScienceDirect

persluchtinjectie


Definition from RIVM:
Persluchtinjectie. Hierbij wordt lucht onder de grondwaterspiegel geïnjecteerd (‘Sparging’) zodat vervluchtiging van vluchtige stoffen optreedt vanuit het grondwater naar de onverzadigde zone (‘Stoomstrippen’).

Example sentence(s):
  • Persluchtinjectie wordt, als Air Sparging / Stripping toegepast voor vluchtige verbindingen met een dampspanning van tenminste 100 N/m2, of een Henry Coëfficiënt van 0,01 zoals olieverontreinigingen met een ketenlengte korter dan C12, aromaten en chloorethenen of in de vorm van Biosparging op andere aëroob afbreekbare organische stoffen. - Soilection.nl  
  • Dit Handboek (Technical Guide) is het resultaat van een vierjarig onderzoek naar ontwerp, dimensionering en uitvoering van persluchtinjectie als techniek voor sanering van verontreinigde bodem en grondwater. - Soilpedia.nl  
  • ersluchtinjectie wordt ingezet ter vervluchtiging van verontreiniging uit het grondwater (in-situ strippen) en voor het inbrengen van zuurstof in het verontreinigde grondwater. Dit stimuleert de natuurlijke en aërobe afbraak. Persluchtinjectie wordt ook vaak ingezet bij chemisch oxidatieve projecten. Door de perslucht verspreidt de oxidant zich beter door het bodempakket. - Oranjewoud
