“…Similar trends have been observed in previous studies reported by Klouche et al (2020) and Bessaim, Missoum, Bendani, and Laredj (2019). After applying EK technology, initial periods of desorption and mobilization of ions from the soil in the aqueous mediums released free charged ionic species.…”

“…By using EK, Kim et al (2013) observed that the removed cations from saline soils (EC = 13.7 dS m −1 ) including Ca 2+ , Mg 2+ , K + , and Na + amounted to 19.5%, 34.4%, 58.9%, and 89.6%, respectively; removed anions including Cl − , NO 3 − , and SO 4 2− amounted to 47.9%, 91.5%, and 67.6%, respectively. Klouche et al (2020) achieved removal rates of 83% and 58% for sodium and calcium ions, respectively, after 15 days of EK treatment. Generally, the EK removal rate of Na + , NO 3 − , and Cl − removal was high compared to the EK removal of Ca 2+ , Mg 2+ , and SO 4 2− (Abou‐Shady, 2016; Choi et al, 2012; Kim et al, 2012; Kim et al, 2013).…”

“…Saline soil can be found on continents including Africa, Asia, Europe, Australia, and the United States of America (Litalien & Zeeb, 2020; Yan et al, 2013). General statistics estimates that globally, 7% of the Earth's land surface area (Cho et al, 2010; Rengasamy, 2006), about 20% of arable soils and half of the uncultivated soils are impacted by salts (Cho et al, 2010; Klouche et al, 2020; Long et al, 2016; Nouri et al, 2017; Scudiero et al, 2016). Coastal lands are one of the main areas affected by soil salinity due to the comprehensive action of human and natural factors, such as marine and terrestrial sedimentation and seawater intrusion (He et al, 2015; Li et al, 2014).…”

This study explored the applications of a vertical electrokinetic system (V-EK), which consists of multilayer electrodes positioned in shallow soil to form an 'electric sieve' to mitigate and prevent soil salinization caused by salts rising from saline groundwater in coastal areas. The experiments were conducted in column reactors in the laboratory. Compared to the control column, the level of ions in the surface soil was significantly reduced after the V-EK treatment, particularly for the column with voltages at 10 V and 20 V. At a voltage of 20 V, Na + was detected at a range of 0.06-0.08 mg g À1 in the surface soil; this is a >99% reduction compared to the controls. Similar efficacy was observed for Cl À in the V-EK column. The concentrations of Cl À were detected with a range of 0.01-0.02 mg g À1 and 0.02-0.06 mg g À1 at the surface soil with a voltage of 20 V and 10 V, respectively, compared to the Cl À concentrations at 0.84-2.70 mg g À1 in the control. After the application of the vertical 'electric sieve', the total salt content of surface soil could be controlled at a low value (<0.25‰) at voltages of 10 V and 20 V, compared to that in the control column (4.86‰). Finally, rising of salts from the artificial saline groundwater was effectively mitigated under voltages of 10 V and 20 V. Results from this work have demonstrated that the 'electric sieve' can effectively mitigate and prevent salts from rising in shallow groundwater to surface soil and reduce soil salinity.

Soil salinity has become one of the environmental issues around the world. The most typical example in Turkey was the soil salinization in Harran and Akçakale Plains in recent years. Especially the Harran Plain has the big potential of water and land resources. Irrigated farming is common in the plain. Excessive and uncontrolled irrigation contributed to the high groundwater level and soil salinity in the region. The deficiency of the drainage network in the farmlands was the most important factor in the salinity. In-field drainage systems are newly established. In some areas, irrigation is conducted through the main drainage channel with high salt content (13.5 dS/m). On the other hand, pumping irrigation waters in Akçakale region have high salt content. This problem has grown especially when dealing with low-permeable soils where conventional remedial techniques are inadequate and often ineffective. Electrokinetic treatment is an innovative and clean technology for the restoration of saline soils. This process has proven to be the most effective, promising technique for the optimal and sustainable improvement of salt-affected soils.
