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

αεροδιασπορά

Definition:
Μια από τις κυριότερες μεθόδους απορρύπανσης του εδάφους.
Κατά την αεροδιασπορά ο ρυπαντής εξαερώνεται µετά από διαβίβαση αέρα από αεροσυµπιεστή. Η διαβίβαση αέρα γίνεται µέσα από κατακόρυφο σωλήνα στην κορεσµένη και ακόρεστη ζώνη. Πλεονέκτηµα της µεθόδου είναι η ταυτόχρονη απορρύπανση
κορεσµένης και ακόρεστης ζώνης.
