Optimization of 2-D Electrode Configuration for Electrokinetic Remediation

The use of 2D non-uniform electric field to enhance in situ bioremediation of 2,4-dichlorophenol-contaminated soil

“…Generally, electrode pairs are adopted to generate 1D electric field, while the configurations of regular polygons are used to produce 2D electric field. In theoretical modeling study, the distribution of 1D and 2D electric field is usually simplified to be linear and radial, respectively, despite more complicated distribution under practical conditions [23]. Previous studies had demonstrated that 1D non-uniform electrical field could effectively enhance the biodegradation of phenolic organics in unsaturated soil [21].…”

Removal of heavy metals from kaolin using an upward electrokinetic soil remedial (UESR) technology

“…There were limited studies where non-uniform electric field was used [16,17]. For example, two-dimensional electric field was proposed for transport across inhomogeneous charged porous media [18].…”

Electrokinetic Remediation

“…This model used the data of Yeung (1990) and it was found that the ®nite element model validated Yeung's experimental data. There are many models formulated, but these are speci®c, e.g., the optimization of 2-D electrode con®guration (Alshawakbeh et al, 1999), ion velocity in soil solution , and modeling of decontamination rate (Baraud, F., et al, 1997). There is a need to work on further quanti®cation and more detailed modeling in electrokinetic remediation with emphasis on electro-osmosis.…”
