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

Injecció d'aire


Definition from Termcat:
Tècnica de tractament del sòl que consisteix en la introducció d'aire al subsòl de manera que es formin unes bombolles que arrosseguen els contaminants volàtils dissolts i es capturin a la superfície per un sistema d'extracció de gas.

Example sentence(s):
  • El disseny d’una actuació de bioremediació, doncs, haurà d’avaluar les necessitats d’oxigen per a dur a terme la degradació i determinar-ne el tipus de subministrament: per injecció d’aire, injecció d’oxigen pur o ús d’alliberadors i productors d’oxigen (vegeu apartat 7.5). - Agència Catalana de l'Aigua  
  • Dessorratge-desgreixatge: en aquest tanc, l’aigua es remou i s’hi injecta aire a pressió. Els greixos suren i es recullen a la superfície. Les sorres cauen al fons i també es recullen. La injecció d’aire accelera aquests dos processos. - Fòrum de la Sostenibilitat  
  • L'aireació (també anomenada air sparging) és una tècnica que es basa en la injecció d'aire o oxigen a l'interior del medi contaminat. - UAB
