Soil Clean-Up by Surfactant Washing. III. Design and Evaluation of the Integrated Pilot-Scale Surfactant Recycle System

Application of sieve‐tray air strippers to the treatment of surfactant‐containing wastewaters

“…related technologies such as vacuum stripping have been found to be very effective for treating contaminated surfactant solutions. Many studies reported to date have made use Ž of packed-tower strippers Clarke et al, 1993;Oma et al, to treatment of surfactant-containing wastewaters, and, if so, to develop a quantitative approach for designing tray airstripping systems for treating surfactant-containing wastewaters.…”

Remediation of soils contaminated by hydrophobic organic compounds: How to recover extracting agents from soil washing solutions?

“…However, surfactant-enhanced SW can be applied to soils contaminated with pollutants such as trichloroethylene, tetrachlorethylene or perchloroethylene. In such case, air stripping and related technologies are relevant for the removal of such compounds from SW solutions [41][42][43][44]. Air stripping is based on the formation of a large air-water interfacial area in order to improve the mass transfer of semi-volatile compounds from the aqueous phase to the gas phase.…”

Hazardous waste treatment technologies

“…Model simulations with calibrated parameters were in good agreement with the experimental data. Clarke et al (199 3b) and Oma et al (1993) designed and evaluated a pilot-scale surfactant recycle system for soil cleanup by surfactant washing. Ninety-nine percent of biphenyl and 98% of toluene were removed from soil using a solution containing 2.5% ofSDS.…”
