The basic electro-kinetic process is defined by forced/induced movement of target pollutants in soil/sand medium under applied electric field low strength between electrodes of opposite polarities. There are several specific mechanisms that contribute to this movement of pollutants. However, one study suggested that the most important ones are electro-osmosis, electro migration, and electrophor...

among the most common types of problematic soils, are probably the expansive ones. one of the modern methods of strengthening and improving the soil in place is the use of electro-osmotic improving treatment. this paper presents the design of an apparatus suitable for electro-osmotic treatment. a soil sample of a high expansive potential was compacted and the effect of electro-osmotic treatment...

Abstract Remediation of contaminated soil and sediment is important for improving the eco-environmental quality. Electro-kinetic remediation (EKR) an environmentally friendly technology to migrate remove pollutants from matrix. This paper analyses mechanism performance EKR heavy metals, organic pollutants, compound pollutants. Moreover, effect optimizing individual through pre-treatment (adding...

Background & Aims of the Study: Azo dyes utilized in industrial processes, such as the textile manufacturing, lead to the creation of huge amounts of colored wastewaters that contain non-organic and organic constituents. Therefore, it is necessary to search for remedies in this regard. This study investigated the degradation and mineralization of Acid red 14 (AR14), which is a mono Azo dye gene...

Millions of people in rural South Asia are exposed to high levels of arsenic through groundwater used for drinking. Many deployed arsenic remediation technologies quickly fail because they are not maintained, repaired, accepted, or affordable. It is therefore imperative that arsenic remediation technologies be evaluated for their ability to perform within a sustainable and scalable business mod...

In recent year large amount of water and wastewater generated from various industries and produce organic matters and contaminated the water, this organic this organic compound in water poses serious problems to public health as well as environment. The advanced oxidation process (AOPs) is one of the advanced treatment method for wastewater remediation. In AOPs, ElectroFenton process (EFP) is o...

Electrokinetically enhanced remediation is an innovative technology that has the potential to remediate hydrophobic organic compound (HOC) contamination in soils and groundwater. A surfactant/cosolvent is used to increase HOC desorption and solubilization, and an applied electric potential facilitates contaminant transport primarily by electroosmosis and/or electrophoresis. Electroosmotic flow ...

In this study, Chemical Oxygen Demand (COD) from a pharmaceutical wastewater (PhW) was reduced by several techniques such as electro-Fenton (EF), photo electro-Fenton (PEF) and activated sludge (AS) processes and the obtained data were compared with each other. The effects of several parameters such as pH, current density, H2O2/Fe2+ molar ratio, volume ratio of ...

Surfactant-enhanced aquifer remediation (SEAR) is widely considered a promising technique to remediate dense nonaqueous phase liquid (DNAPL) contaminations in-situ. The costs of a SEAR remediation are important and depend mostly on the setup of the remediation. Costs can be associated with the installation of injection and extraction wells, the required time of the remediation (and thus labor c...
