with inert gas or dosing liquid N2 was, in some audits, less effective at controlling HSO than the use of vacuum.
Therefore, these plants need to have FDA-compliant nitrogen sparging
and blanketing practices to ensure high purity demineralized water.
Dupont, Field monitoring and performance evaluation of an in situ air sparging
system at a gasolinecontaminated site.
Gold traps were analyzed for Hg(0) on board the ship immediately after sparging
The most widely used cleanup methods that take advantage of chemical volatility are air stripping, SVE and air sparging
is an in situ (in-place) remedial technology that reduces concentrations of chlorinated solvents adsorbed onto soils and dissolved in groundwater.
The objective of research at Oklahoma State University was to investigate the use of microbubble sparging
to improve oxygen transfer and product yield during xanthan gum fermentation.
Aqueous dilutions of these two volatiles were adjusted in sparging
bottles to levels previously determined by Bargmann, et al (7) to yield an approximate chemotaxis index with C.
Tests show MAG degassing rate constants nearly identical to traditional compressed air sparging
with gaseous nitrogen preserves taste for Italian winery.
is stopped when the run off concentration has reached a level where transfer to the wart kettle is no longer desirable.
These included soil vapor extraction, air sparging
, steam stripping, low-temperature thermal, bioremediation, and electrokinetic remediation.
engineers sank 31 vertical sparging
points throughout the plume of contamination at the Long Beach site.
The hydrocarbon contaminant released through a leak can be separated from soil and/or ground water by using air sparging
, bioventing or vapor extraction.
Examples of such metal handling are dipping of ladles, stirring, pouring, and even degassing - as bubbles of sparging
gas break the surface and momentarily expose unprotected aluminum to the atmosphere.
