Plume migration

BioSparge has the advantages of being relatively inexpensive, controlling plume migration, creating no air emissions and no waste disposal. 

The overall objective of this research was to evaluate the effects of cosolvent addition on the ability of an ethoxylated nonionic surfactant to recover PCE from a heterogeneous, 2-D system. The specific tasks of this work were to (a) quantify the PCE solubilization rate and capacity in the presence and absence of a representative cosolvent (EtOH) and (b) investigate the effects of EtOH addition on surfactant delivery, plume migration and PCE recovery in a 2-D, layered sand tank. A representative nonionic surfactant, polyoxyethylated (POE) (20) sorbitan monooleate (Tween 80), was selected for study because of its capacity to solubilize PCE ( 0.7 g PCE/g surf at 20°C) and relatively high interfacial tension with PCE (5 dynes/cm). EtOH was chosen as the representative cosolvent because of its relatively low density (p = 0.79 g/cm1) and regulatory acceptance.

The coupled reactive transport model is designed to simulate the acid plume migration under this cover and attenuate reclamation plan. An 800 m strip along cross-section A-A (Figure 6.2) was discretized into 200 cells (Figure 10.4). Each cell is 4 min length. The time step is 0.08 year.
