Soil flushing of residual transmission fluid: application of colloidal gas aphron suspensions and conventional surfactant solutions
D Roy, RR Kommalapati, KT Valsaraj, WD Constant - Water Research, 1995 - Elsevier
An innovative technology using Colloidal Gas Aphrons (CGAs) is applied in this study to
flush residual levels of a light non-aqueous phase liquid (LNAPL) such as automatic
transmission fluid (ATF) from a Superfund site soil. Performance of CGA suspensions is
compared with that of conventional aqueous anionic surfactant solutions under both gravity
stable (downflow) and gravity unstable (upflow) conditions. CGA suspensions were found to
be more effective in washing ATF under both downflow and upflow modes. The …
