air sparging

GBK English to Romanian Tech/Engineering 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 sentences:
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)

barbotarea cu aer

constă în injectarea unui gaz (de cele mai<br />multe ori aer) sub presiune sub partea superioară a<br />pânzei freatice. Aerul care se propagă prin zona saturată<br />și urcă către suprafață creează canale de aer care intră<br />în contact cu poluanții dizolvați sau adsorbiți, ceea ce<br />permite volatilizarea acestora. Aerul se încarcă astfel<br />cu poluanți și este evacuat prin puțuri de extracție<br />poziționate alternativ cu puțurile de injecție către<br />sistemul de tratare a gazelor (venting). Această
Example sentences:
Barbotarea in situ (sau injecție și aerarea in situ) (Depoluarea siturilor contaminate)
barbotarea cu aer, injectarea aerului în scopul de a determina antrenarea compuşilor chimici poluanţi şi transportul lor la suprafaţă (Metode de remediere in-situ)
barbotage n. m. Technique de décontamination de l'eau souterraine et des sols, qui consiste à injecter de l'air dans la zone saturée d'eau afin de favoriser le déplacement des contaminants volatils vers la zone non saturée d'eau, d'où ils sont la plupart du temps aspirés vers la surface à l'aide d'un système de ventilation pour être traités.
