In Situ Mixed Region Vapor Stripping in Low-Permeability Media. 3. Modeling of Field Tests

Sustainable in-well vapor stripping: A design, analytical model, and pilot study for groundwater remediation

“…Similar to the thermal model developed by Gierke et al (1995) to simulate in-situ mixed region vapor stripping processes in a CMFR, the SIVS model accounts for and balances the potential disequilibrium in mass transfer during vapor stripping. Solute transport parameters in the SIVS model were calibrated to the results of a pilot study.…”

Chemically enhanced mixed region vapor stripping of TCE-contaminated saturated peat and silty clay soils

“…3) are described in detail, including a discussion of treatment mechanisms and how these are affected by the physical and chemical properties of the mixed soil (also in Sect. 3). The transferability of the laboratory test results to a full-scale application, as well as a projection of expected costs for achieving various remediation goals at the Michoud Rinsewater Impoundment, is presented (Sect.…”

“…Triplicate samples were collected at time 0 of vapor stripping, and single samples were collected for the rest of the time intervals. Afier it was determined that significant removals did not occur beyond 3 hours of vapor stripping, the remaining 5 of the 16 cores treated were vapor stripped for 180 min. Duplicate samples were taken at 0, 15, 30, 60, 120, and 180 rnin of vapor stripping.…”

In Situ Mixed Region Vapor Stripping in Low-Permeability Media. 1. Process Features and Laboratory Experiments

“…Several models for the transport of VOCs in unsaturated soil have been reported in the literature (1 [7][8][9][10][11][12][13][14][15][16][17][18][19][20] and have been used to model removal of VOCs in SVE systems (20).
