Dear Editor of Land Degradation & Development
Please consider our manuscript “Application of a Vertical “Electric Sieve” to Mitigate and Prevent Salinization in Coastal Soil ” for publication in the Land Degradation & Development.
Soil salinization is a key soil degradation factor in the worldwide, especially in the coastal areas. In coastal areas, landscaping is enormously restricted due to its higher soil salinity, and this low vegetation cover in coastal areas could lead to a fragile ecosystem for coastal saline land. Therefore, to find an effective and economic salt controlling technology for this kind soil with low permeability porous media is a challenge, where re-salinization is easily happened because of the continuous supplement of salts from the shallow saline phreatic water and sea.
In this study, a Vertical Electrokinetic system (V-EK) with multilayer electrodes was considered as an “Electric Sieve” were proposed to mitigate and prevent the surface soil salinization caused by salts rising from shallow groundwater in coastal area were explored. Different to the traditional perspective of saline soil restoration that used the horizontal electrical field configurations to transfer contaminants to both side of electrodes in combination with the saturated water conditions or irrigation, we focus on the mitigation and inhibition of the salt rising from shallow groundwater by the vertical EK system with multilayer electrodes, which could be considered as an “Electric Sieve”. The results showed that different salts rising from shallow groundwater were effective inhibited under the V-EK system. Moreover, it will be energy saved if the power was produced by solar.
