A study of the application of electrokinetic (EK) remediation and Permeable Reactive Barriers (PRB) using recyclable Foods Scrap Ash (FSA) in multiple contaminated soils was carried out. An FSA was chosen as a PRB fill material due to its highly efficient capacity for contaminant removal. Acetic acid and Brij30 were used as enhancers on copper and phenanthrene, respectively, to improve EK remediation performance in removing the heavy metal and organic contaminants. Copper adsorption in PRB was so substantial that the confirmed removal efficiency was 83.86–90.17% and the remaining amount was 105–212 mg. While a high removal efficiency of acetic acid was observed on copper in multiple contamination soils; the removal of phenanthrene was hardly detected and the recovery rate of the contaminant was low during pretreatment. Therefore; an additional study of pretreatment on the phenanthrene-contaminated kaolinite needs to be performed.

This paper presents the development of a new remediation technology of contaminated soil and groundwater using humic acid (HA) in permeable reactive barrier (PRB) for pipeline leakage. The objective of this study was to use humic acid that could be medium within a PRB to filter complex contaminated soil and groundwater containing chromium. Leakage of pollutants (such as hydrocarbon、gasoline、oil、wastewater、heavy metal et al) has a large economic and environmental impact. When a pipeline leak is large or undiscovered for a longer period of time, substantial volumes of gases and liquids can leak into the soil and groundwater, which can develop into dangerous situations involving costly remediation works. Traditional methods for remedying contaminated soil and groundwater from pipeline leakage, such as drilling and geochemical analysis, are destructive, time consuming and expensive. A PRB was determined to be the best option for remedying groundwater that has become contaminated with a wide range of organic contaminants (i.e., benzene, toluene, methylbenzene, xylene and polyaromatic hydrocarbons), heavy metals (i.e., lead and arsenic). PRB is installed in or down gradient from the flow path of a contaminant plume. The contaminants in the plume react with the media inside the barrier to either break the compound down into harmless products or immobilize contaminants by precipitation or sorption. It is made up of humic acid that reduce contaminants. With the development of industry and agriculture, environmental contamination has become more and more serious, especially heavy metal pollution, have been a major environmental issue, drawing much scientific and public attention. Chromium is identified as “priority pollutant” by the United States Environment Protection Agency (US EPA). the measurements show a significant increase of the adsorption of Cr (VI) because of the complexion reaction between HA and Cr (VI) occurred under acidic condition. It could be concluded that HA could be used effectively on remediation of Cr (VI)-contaminated soil and groundwater in a wide range of pH, with or without sunlight.

Abstract Research on soil remediation continues to develop, one of which is electrokinetic remediation combined with a permeable reactive barrier as a medium to prevent the migration of metals removed from the anode and cathode spaces. Thus, it is hoped that there is no need for reprocessing the residue resulting from electrokinetic remediation. This study aims to conduct a bibliographical analysis related to electrokinetic remediation coupled by permeable reactive barriers for heavy metal contaminated soil and to examine the effect of using various types of reactive barrier materials and their placement on the pollutants removal in the soil. Based on the results of bibliographic analysis, 26 relevant scientific articles were obtained, and the most publications in 2020 with 27% additional article publications are found. China and Environmental Science and Pollutant Research are the countries and journals that contribute the most to publications related to EK-PRB on heavy metal polluted soils.

Electrokinetic remediation deserves particular attention in soil treatment due to its peculiar advantages, including the capability of treating fine and low permeability materials, and achieving consolidation, dewatering and removal of salts and inorganic contaminants like heavy metals in a single stage. In this study, the remediation of artificially lead (II) contaminated soil by electrokinetic process, coupled with Eggshell Inorganic Fraction Powder (EGGIF) permeable reactive barrier (PRB), was investigated. An electric field of 2 V cm-1was applied and was used an EGGIF/soil ratio of 30 g kg-1 of contaminated soil for the preparation of the permeable reactive barrier (PRB) in each test. It was obtained high removal rates of lead in both experiments, especially near the cathode. In the normalized distance to cathode of 0.2 it was achieved a maximum removal rate of lead (II) of 68, 78 and 83% in initial lead (II) concentration of 500 mg-1, 200 mg-1 and 100 mg-1, respectively. EGGIF (Eggshell Inorganic Fraction) proved that can be used as permeable reactive barrier (PRB) since in all the performed tests were achieved adsorptions yields higher than 90%.

Permeable reactive barriers were developed for phosphorus removal. The barrier consists in an organic-inorganic hybrid material, which allows water and others species to flow through it, while selectively removes the contaminants. Polyethylene oxide (POE) and aluminium oxide (Al2O3) were used as the organic and the inorganic parts, respectively. The hybrid material was obtained by sol-gel reaction, using aluminium isopropoxide as inorganic percursor in order to attain Al2O3. The hybrid material produced was characterized by FT-IR spectroscopy and thermogravimetry. The previous tests for phosphorus removal have shown the effectiveness capacity of the developed material to remove it.

It is an indisputable fact that any environmental clean-up technology generating certain kind of effective result would be easily supported. One of them includes Permeable reactive bio-barrier which is an innovative technology started from 90’s to treat a variety of contaminants along the natural gradient flow of groundwater through immobilization or transformation of pollutants into less toxic and harmful form. Despite of any broad acknowledgement, there are lesser known knowledge about use of microorganisms in permeable reactive barriers, mingling of microorganisms with other reactive media and their effect on each other’s reactivity. The current review deals with an overview of the types of reactive media used in Permeable Reactive Barriers (PRBs) as well as different bio-barriers (PRBBs) utilized for the treatment of various contaminants, long–term performance of permeable reactive barrier and combination of microorganism and reactive media to look forward for their symbiotic relationship in permeable reactive barrier for environmental remediation.

Reactive Barriers

As precipitation percolates through a landfill, it comes in contact with decomposing waste ranging from food wastes to factory wastes even to hazardous wastes. That water can then leach elements from the wastes and become contaminated forming what is typically called landfill leachate. Leachate has the potential to cause many health problems if allowed to reach the groundwater and every effort is made to slow and minimize its effect. The most common way of dealing with leachate is to pump it out of the base of the landfill with a series of pipes and pumps, but what about the treatment of the leachate in‐situ through the use of a permeable reactive barrier? Is it a viable solution?
