Abstract:
High energy input and chemicals additions are typically needed to deal with persistent pollutants, organic and inorganic, and organometallic complexes in wastewater. Particularly, organometallic complexes decrease the removal efficiency for other pollutants being treated with conventional technologies, which can lead to high operational costs and residues formation. The improperly treated wastewater contains nutrients (nitrogen and phosphorus), heavy metals, and persistent organics, which should be removed or recovered before discharging. Electrochemical technologies can achieve concomitant removal of persistent pollutants and resource recovery from wastewater, with the benefits of low chemical input, cost-effectiveness and reduced water consumption. In this review, we provide an overview of electrochemical technologies for the separation of organics and inorganics and their subsequent recovery. The focus is placed into electrodeposition, electrodialysis, membrane electrolysis, electrochemical oxidation, capacitive deionization, and bioelectrochemical systems. The main challenges considered at present are i) the cost and longevity of the materials, ii) the process efficiency and selectivity and iii) the complexity of the wastewater matrices. In this review it is projected that in the near future, the electrochemical separation and recovery of organics and inorganics will be preferred, as electrochemical cells powered by renewable energy can serve for decentralized and off-grid treatment approaches.

Abstract:
The concentrations of pollutants in soil samples collected in and around a dumpsite in Heze, Shandong, China, were investigated, and the potential ecological and health risks of these pollutants were assessed. Seventeen soil samples from five different locations were analysed for pollution characteristics, and the target pollutants included inorganic pollutants and heavy metals as well as volatile organic compounds/semivolatile organic compounds (VOCs/SVOCs). Results showed that the mean concentration level of each pollutant from the interior area was relatively higher than that from the boundary area of the dumpsite. Inorganic pollutants and heavy metals were detected in all of the soil samples. According to potential ecological risk assessment with environmental background values of Shandong as screening values, heavy metals in majority of the samples pose low ecological risk to the ecosystem except Hg. Hg poses a considerable or very high risk because of its high levels of accumulation. In consideration of future land use pattern, human health risks derived from environmental exposure to heavy metals were assessed. Carcinogenic risk and noncarcinogenic hazards for adults are acceptable, while noncarcinogenic hazards for children exceed the safety threshold. The health risks are primarily attributed to oral exposure to As and Cr.

Abstract:
The present review discusses various alginate hydrogel adsorbents with unique adsorption performance in environmental remediation. Novel alginate composites were developed with, high swelling capacity and capable of adsorbing toxic inorganic and organic pollutants. Alginate hydrogel adsorbents were developed with a single network and double network structure with excellent adsorption ability in removal of toxic inorganic and/or organic pollutants. Alginate with single or double network composite hydrogels were developed when alginate was combined with graphene/chitosan/polymer to get superior adsorbents in removal of toxic pollutants. Acrylic acid/alginate hydrogel in recent studies are efficient in the elimination of inorganic and organic contaminants. This review will generate interest to researchers to develop novel alginate composite hydrogels with unique properties in the adsorption of toxic inorganic, organic contaminants. This work provides a worthy challenge and the future possibility of designing novel alginate materials for various applications.

Abstract:
Abstract The degree of soil pollutants in the Dunaújváros area has been monitored regularly at 10 sampling points of the town from the upper 0–20 cm and lower 20–40 cm layers of the soils. The quantity of some organic (PAH, TPH) and inorganic (toxic metal) pollutants were determined by GC-MS and ICP analyzation. Microbial status, such as the total cultivable bacteria (CFU) and total catabolic enzyme activity, measured by fluorescein diacetate analysis (FDA) were also estimated. The area of the industrial town could be divided into more and less contaminated regions, although the measured pollutants were far below the estimated permissible limits. However, at some of the more polluted soils even triple amounts of contaminants could be measured compared to the lesscontaminated sites. Among inorganics the Zn microelement reached the highest levels (average is about 100 mg·kg−1 soil), which could be related to the heavy industrial activity. A positive correlation appeared among the organic and inorganic pollutants and also between the pollutants and the measured enzymatic values. The enhanced FDA activity was found at the most contaminated sites preceding the potential “loss of function” on a long-term basis. The fast and reliable microbial parameter could be suggested as further regular monitoring tool.

Abstract:
This paper describes a study of the treatment of 2,4-dichlorophenol (2,4-DCP) with an ethylenediamine-N,N′-disuccinic-acid (EDDS)-modified photo-Fenton system in ultrapure water and different natural waters. The results showed that the EDDS-modified photo-Fenton system is adequate for 2,4-DCP degradation. Compared with a medium containing a single organic pollutant, the removal of pollutants in a more complex medium consisting of two organic compounds is slower by around 25 to 50% as a function of the organic pollutant. Moreover, 2,4-DCP can be further effectively degraded in the presence of organic materials and various inorganic ions. However, the photodegradation of 2,4-DCP in different natural waters, including natural lake water, effluent from domestic sewage treatment plants, and secondary effluent from pulp and paper mill wastewaters, is inhibited. Chemical compounds present in natural waters have different influences on the degradation of 2,4-DCP by adopting the EDDS-modified photo-Fenton system. In any case, the results obtained in this work show that the EDDS-modified photo-Fenton system can effectively degrade pollutants in a natural water body, which makes it a promising technology for treating pollutants in natural water bodies.

Abstract:
Presently water pollution is the one of the major threats faced by living things all over the world. The main cause of water pollution is its effect on the life of aquatic animals. Organic, inorganic, microbial and other pollutants often mix with water bodies mainly due to human activities. Because of the presence of pollutants in water, the amount of dissolved oxygen level can be decreased which in turn affect the survival of aquatic life. The pollutant water may enter the agriculture fields and damage the plants extensively. The methods, such as, coagulation, adsorption, foam floating, electrodialysis, capacitive deionization, etc. are presently employed to treat the waste water. Among these methods, heterogeneous photocatalytic degradation is considered to be a good method because of its low cost and environmental friendliness. In this review, the decontamination of different kinds of organic, inorganic and microbial contaminants in water with different photocatalysts process is presented.

Abstract:
As water management is still a problem of international concern, scientists and practitioners are collaborating to develop new tools and methods to improve and help in the decision-making process. When addressing the priority pollutant monitoring and impact assessment, the ecotoxicity effects, carcinogenic and non-carcinogenic, should be considered together with the exposure factor and health hazards. The main goals of this study were to assess the ecological and health hazards and to apply integrated impact and risk assessment based on the ecotoxicity and exposure factors of each priority pollutant present in the aquatic ecosystem. This study used as a database the measured concentrations of 5 inorganic and 14 organic priority pollutants from the Siret river basin from NE Romania, from 18 river sections monitored in the period 2015–2020. The USEtox methodology and a new integrated index for environmental impact and risk assessment were developed and applied to evaluate the ecological and health hazards and environmental impacts and risks within the river basin. The total impact scores for heavy metals ranged from 2 × 103 to 2.25 × 109, and those for organic pollutants ranged from 2.72 × 10−1 to 2.95 × 106. The environmental risk in the case of inorganic priority pollutants ranged between 5.56 and 3136.35, and that in the case of organic pollutants was between 4.69 and 4059.17. The results revealed that there is a major to catastrophic environmental impact in almost all monitored river sections (10 out of 18), and the overall risk exposure was found to be at a significant to a major level. This study proved the harmful effects that the priority pollutants may have, even in very small concentrations, on non-target organisms and suggests that greater control over the pollution sources and mitigation of environmental impacts and risks should be applied.

Full text
Abstract:
Photodegradation is the chemical conversion of large, toxic, and complex molecules into non-toxic, simpler, and lower molecular weight species due to light exposure. Heterogeneous photocatalysis has sufficient potential to degrade toxic organic pollutants present in wastewater. As industries discharge their effluents containing organic pollutants into natural water bodies, which penetrate into the subsurface through connected pores it is necessary to study this process in natural or tap water. Tap water (TW) is mainly obtained from underground wells having inorganic salts in a minute quantity with a conductivity of 500 μS/cm. TW contains inorganic anions, which affect the photocatalytic activity and photocatalysis process. The aim of this review is to evaluate the effect of TW on the photo-degradation of organic pollutants such as dyes, pharmaceutical products, pesticides, etc., with the support of the literature. The TW had a diverse effect on the photodegradation of organic pollutants; either it may enhance or decrease the rate of pollutants’ photodegradation.

Abstract:
Pollution of fresh water with organic pollutants and heavy metals has an impact on the environment of the River Nile in Egypt. The environment has become increasingly contaminated by inorganic and organic pollutants which accumulate in the food chain and affect the human health. The pollution of the fresh water environment by heavy metals and organic pollutants is due to the increasing action of flowing out discharge from various industries. Three heavy metals; Cu, Pb, and Zn and organic pollutants as DDT, Chlordane, dieldrin and butylene were investigated in the present study in freshwater and sediment during the year (Autumn2016-summer2017) .The investigated samples were collected from Rashid, Egypt. The present study reported that the mean concentration level of both heavy metals and organic pollutants were correlated in the sediment and in the fresh water of Rashid at p< 0.001.

This work is the first one conducted in Veneto region, Italy with collaboration of ARPAV including important organic (OC/EC and PAHs) and inorganic pollutants (trace elements), which were characterized for longer period of time in order to quantify the source contributions of PM2.5 at regional scale (Veneto) using receptor modelling [Factor Analysis]. 360 samples were collected from six major cities located in 6 Provinces during April 2012- February 2013. The results show that OC, EC, PAHs and Trace elements exhibited higher concentration during winter month in all measurement sites, suggesting that the stable atmosphere and lower mixing layer play important role for the accumulation of pollutant. Meteorological parameters especially wind velocity and temperature play significant role in pollutant accumulation from local sources. Finally, possible sources of particulate matter have been characterized using Conditional Bivariate Probability Function, diagnostic ratios and Factor Analysis and results indicated that biomass burning for household heating and cooking, followed by vehicular traffic, oil combustion and crustal are the main sources of particulate matter in Veneto region.

Abstract:
This work explores the synthesis and photophysicochemical properties of zinc phthalocyanines when conjugated to cobalt ferrite magnetic nanoparticles. Phthalocyanines with amine and carboxylic acid functional groups were synthesised so as to covalently link them via amide bonds to cobalt ferrite magnetic nanoparticles with carboxylic acid and amine groups, respectively. Spectroscopic and microscopic studies confirmed the formation and purity of the phthalocyanine-cobalt ferrite magnetic nanoparticle conjugates which exhibited enhanced triplet and singlet quantum yields compared to the phthalocyanines alone. The studies showed that the presence of cobalt ferrite nanoparticles significantly lowered fluorescence quantum yields and lifetimes. The conjugates not only showed much higher singlet oxygen quantum yields compared to the phthalocyanines alone but were also attractive because of their magnetic regeneration and hence reusability properties, making them appealing for photocatalytic applications. The photocatalytic ability of some of the phthalocyanines and their conjugates were then tested based on their photooxidation and photoreduction abilities on Methyl Orange and hexavalent chromium, respectively. For catalyst support, some of the zinc phthalocyanines, cobalt ferrite magnetic nanoparticles and their respective conjugates were successfully incorporated into electrospun polystyrene and polyamide-6 fibers. Spectral characteristics of the functionalized electrospun fibers confirmed the incorporation of the photocatalysts and indicated that the phthalocyanines and their respective conjuagates remained intact with their integrity maintained within the polymeric fiber matrices. The photochemical properties of the complexes were equally maintained within the electrospun fibers hence they were applied in the photooxidation of azo dyes using Orange G and Methyl Orange as model organic compounds.

Abstract:
In recent years water contamination is reaching alarming levels, since the concentration of pollutants present in seas, lakes and streams has far exceeded water self-purifying capacity. The most widespread sources responsible for water pollution are urban and industrial dumps containing a vast range of dangerous substances. Despite wastewaters are always subjected to purification treatments, a complete remediation is not always possible. The most common pollutants are heavy metal ions and organic compounds such as phenolic compounds, polybrominated diphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), pesticides and synthetic dyes. All these substances are highly stable and can easily bioaccumulate in living organisms as xenobiotic molecules, causing chronic and acute toxicity or carcinogenic and mutagenic effects. Furthermore, substances as dyes can cause changes to the aquatic ecosystem as they absorb the sunlight limiting its penetration into deep waters, thus inhibiting the photosynthesis of aquatic plants and thus limiting the water re-oxygenation capacity. In such a scenario, in the last few decades the scientific community has put a great deal of effort into the improvement of wastewater remediation processes. Among the various treatments, adsorption is one of the most useful thanks to its simplicity and low cost. The great advancement in nanotechnology has paved the way for new highly effective nanostructured adsorbent materials. These generally porous nanoadsorbents are characterized by a high surface area and high surface/volume ratio, which greatly influence their adsorption capacity. The purpose of this thesis work was the development of new mesoporous adsorbents, namely functionalized ordered mesoporous silica (OMS) and metal organic frameworks (MOFs) for the removal of heavy metal ions and organic dyes two types of pollutants commonly present in wastewaters.. Both OMS and MOFs are characterized by high surface area, high surface/volume ratio, geometrical order, and easy synthesis or functionalization. SBA-15 OMS and Fe-BTC type MOF have been successfully synthesized and characterized by means of different techniques, such as small angle X rays scattering (SAXS), powder X-rays diffraction (XRD), N2 physisorption, transmission and scanning electron microscopy (TEM and SEM), thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FT-IR). SBA-15 was functionalized with two different organic ligands, namely triethylenetetramine (TETA) and 2,8-dithia-5-aza-2,6-pyridinophane macrocycle (PyNS2), to obtain two different adsorbents, named SBA-TETA and SBA-PyNS2 which have been tested against some heavy metal ions (Cu2+, Zn2+ and Cd2+). The Fe-BTC, without further modifications, was instead tested as an adsorbent of two highly toxic organic dyes, such as Alizarin red S (ARS) and Malachite Green (MG). All adsorption experiments were monitored using Inductive Coupled Plasma Optical Emission Spectroscopy (ICP-OES) or UV-Vis Spectroscopy. This allowed the experimental determination of the adsorption capacity q of the three adsorbents, their thermodynamic and kinetic parameters. In the case of SBA-15-based adsorbents, further investigations on their properties were carried out by means of potentiometric titrations.

Silver nanoparticle (AgNP) was synthesized using a medicinal plant Acalypha wilkesiana leaf extract through bottom-up approach. synthesis of nanoparticle via green route is simple, easy to handle and inexpensive in comparison of physical and chemical methods. Phytochemical screening of Acalypha wilkesiana determines the presence of coumarins, flavonoids, sterol, tannin, phenol and saponin. Synthesis of nanoparticle were detected at regular intervals with proper characterization technique majorly include UV-Vis spectroscopy. Further characterization involves the Scanning Electron Microscopy/ Transmission Electron Microscopy (SEM/TEM) which determines the size and shape of the nanoparticle. Fourier transform infrared spectroscopy helps in finding the biochemical function group of plant extract which serves as reducing and capping agent in nanoparticle synthesis. And crystal nature of nanoparticle was analysed via X-ray diffraction (XRD). Here we aimed the remediation of polluting aqueous solution via green route of silver nanoparticle synthesis and study the photocatalytic activity of organic dyes and ability to detect the toxic metal like Pb, As, Ni, Hg, Cr, Co, Fe, Mn, Pd and Se.

Philosophiae Doctor - PhD
Organic and inorganic pollutants are two broad classes of pollutants in the environment with their main sources from waste waters that are indiscriminately dumped from chemical related industries. Among the organic pollutants are dyes that come as effluents from the textile industries. Toxic metals are the main inorganic pollutants with their sources from industries such as mining, electroplating, batteries etc. The presence of both classes of pollutants in the aquatic environment poses a serious threat to aquatic organisms and humans who depend on these waters for domestic purpose. Therefore, this research focused on the fabrication of materials and designing of methods for removal of both classes of pollutants from their aqueous solutions.

Abstract:
Water pollution is one of the most serious environmental problems the world faces today. Due to a progressive change in environmental perception in developed countries, great attention is currently given to specific pollutants, both of natural and human origin, often labeled as organic and inorganic micropollutants. Micropollutants can have severe implications both on ecology and human health even in very low concentration in water, being potentially toxic and carcinogenic, and are included in the EU PP (Priority Pollutants) list. The current water purification treatments are affected by many limitations and do not significantly lower the concentration of micropollutants, unless the treatment is carried out, if technically possible, to such an extent to become not economically sustainable. In this context, the aim of this PhD thesis is the development and characterization of polymeric absorbing materials for the quantitative and reversible removal of organic and inorganic micro-pollutants from water. These materials are based on poly(amidoamine)s (PAAs), cyclodextrins and renewable resources such as guar gum and hemicelluloses. The synthetic procedures adopted are simple, eco-friendly and employ water as solvent. The materials proved able to absorb either inorganic (Cu(II), Co(II), Cd(II), Pb(II), Mn(II), Zn(II), Fe(II), Ni(II), Cr(VI)) or organic micropollutants (chloroform, halothane, tetrachloroethylene, o-toluidine) and were competitive with other sorbents reported in literature. They could also be regenerated and recycled without loss of absorption performance.

Abstract:
Graphitic carbon nitride (g-C3N4) heterojunction composites with the semiconducting metal oxides, CeO2, ZnO and TiO2 are prepared in situ by co-calcination of the precursor materials or by a solvothermal method. The structural, morphological and the optical properties of the prepared materials are studied using various microscopy and spectroscopy techniques. The synthesized composite materials, CeO2/g-C3N4, ZnO/g-C3N4 and TiO2/g-C3N4 are more efficient in the photocatalytic degradation of the water pollutants indigo carmine (IC) and atrazine than the pure metal oxide, g-C3N4, or their physical mixtures. The CeO2/g-C3N4 and ZnO/g-C3N4 composites also exhibit improved degradation efficiencies of atrazine as compared to the individual metal oxide or g-C3N4 materials. The improved photocatalytic activity of the composites are attributed to the effective electron-hole charge separation within composite heterojunction, resulting from the well matched energy levels of the metal oxide and g-C3N4. This strategy could be helpful for the synthesis of other metal oxide and g-C3N4 composites for photocatalytic applications.

Abstract:
Qatar sits in the middle of the world’s most important hydrocarbon producing areas where significant regional refining activity and shipping traffic take place. In addition to significant local coastline, development prominently along the eastern coast, has taken place over recent decades. Protecting Qatar’s marine ecosystems from the adverse effects of environmental contaminants is a core component of the Environmental Development pillar within the National Vision 2030. However, a limited number of studies have investigated contaminant concentrations in the coastal environment of Qatar. The accumulation of contaminants in aquatic environments can affect coastal and marine ecosystems, and cause adverse effect on marine organisms and human health. This study aims to determine contamination in Qatar’s coastal environment by measuring organic and inorganic contaminants, along with physiochemical parameters, at four sites located on the contrasting east and west coast of the country. The Pearl Oyster Pinctada radiata, which is considered an iconic organism in Qatar, was used to determine a baseline of contaminants in an aquatic organism. Surface seawater, surface sediment and oysters were collected four times over two years in different seasons from the four sites. In-situ parameters (temperature, pH, and salinity), and abiotic parameters (TOC and grain sizes) were measured for seawater and sediment. Organic (TPHs, PAHs) and inorganic contaminants (trace metals including: Cd, Cu, Cr, Ni, Pb and Zn, T-Hg) were measured in all samples. Overall, Al Wakra (higher in boat traffic and fueling activities) on the east coast reported the highest levels of contaminants. High PAHs were observed in oyster tissues, while high Pb was noted in seawater and high Zn was observed in sediment and oyster. Benzo (a) pyrene was the highest compound detected in oyster. However, high TPHs were also noted in oyster tissues from Simaisma. At Al Khor, also on the east coast, high level of TPHs were recorded in seawater, while high PAHs and TOC observed in surface sediment, which had a relatively higher clay and silt content than other sites. Umm Bab (with a desalination plant near the coast), the sole sample site on the west coast, showed the highest level of TOC in seawater and sediment, highest Ni in seawater and highest total mercury in oyster. Our results, in general, report lower levels in seawater and sediment compared to other studies in the region and more widely; however, in oysters most of the contaminants are higher when compared to international guideline values. These higher levels indicate the potential for these filter-feeding organisms to absorb contaminants into their tissues from the environment that surrounds them. Additionally, bioaccumulation can occur. This study provides background information for further investigation to understand the presence and distribution of organic and inorganic contaminants in Qatar’s rapidly changing coastal environment. It indicates the usefulness of applying a holistic view to environmental monitoring including the use of biomonitoring.

Abstract:
The study reveals the development of appropriate innovative sorbents based on clay material for arsenic and p-nitrophenol sorption using iron oxy-hydroxide and surfactant modification. Natural and manufactured clay were chosen for comparison of modification efficiency to obtain the best sorption results for As (V) and p-nitrophenol. Obtained results indicate that modification of clay with iron compounds and various surfactants significantly improve the sorption capacity of newly developed materials used for sorption of inorganic and organic compounds from aqueous solutions in landfill leachates.Natural clay minerals have received a lot of attention as potential sorbents, because of their abundance, cost-effectiveness, high sorption and ion-exchange properties [1]. Clay minerals can be modified using different approaches to obtain innovative materials for application as sorbents in the removal of inorganic and organic pollutants from leachates, wastewater, groundwater and soil [2, 3]. Modification with surfactants improves hydrophobization needed if interaction with low polarity organic molecules is necessary, but chemical modification with inorganic species, e.g., hydrated iron supports the physical improvement of sorption and ion exchange process in order to benefit the treatment of media from inorganic pollutants [4]. Materials achieved better properties for specific remedial applications regarding heavy metals and metalloids, prepared organoclays from hydrophilic montmorillonite by intercalating cationic or nonionic surfactants can interact with organic molecules of differing polarity and serve as immobilizers for organic molecules and toxicants, e.g., phenols and NOCs. Further studies will reveal improved properties to benefit landfill leachate treatment, wastewater engineering and environmental remediation industries.

Abstract:
Soil and groundwater as the leachate may contaminate surrounding watersheds, thus different pollutants from closed dumps and landfills pose significant risks to human health and ecology. Pollution may lead to soil and water degradation however it might be diminished through sustainable dump site closure projects and processual management. Several decades of clays and clay minerals studies lead to modified clay composites concept that is one of the potential promising solutions for building the landfill covering material and serve as capping biocover layer at the same time. As humic substances are constituents of soil organic matter, pollutants can be sorbed on the surfaces of complex molecules. This kind of humic acid-clay mineral composite materials thus might become as low cost building material component - covering material. Construction of such layer are to be performed as a combination of clay-humic composites and landfill mined fine fraction of waste with small amendment of natural soil. Several hypotheses that are already proven has to be mentioned: a) Clay minerals produce composites with humic substances; 2) Clay-humic complexes reduce through sorption both organic and inorganic pollutants; 3) Low risk of toxic byproducts from landfill mined waste fine fraction can be the problem; 4) Such composites mostly would trap toxic contaminants (e.g., pharmaceuticals) found in reworked fine fraction of waste. The aim of the work is to provide alternative solution for landfill closure by giving theoretical considerations from multidisciplinary knowledge of environmental engineering, chemistry and waste management.

Abstract:
The aim of this study was geochemical and mineralogical assessment of materials from two already closed pits. Total testing and leachate testing (Equilibrium Leach Test and Sequential Leach Test) of topsoil, waste stabilized with lime and underlying rock was performed on composite samples. Analysis of underground water from underlying rock was also accomplished. Major pollutants in stabilized waste from investigated locations differ. High total values of some heavy metals in stabilized waste from one of the investigated locations can probably be attributed to high barite content (mercury, zinc and cadmium) and pipe dope (lead). Mercury, zinc and cadmium are enriched in the organic-sulfide fraction that might indicate they are tied up as sulfide impurities in barite. In distilled water lecheate of stabilized waste from this location higher concentrations of Pb, Hg and TOC were observed. In the stabilized waste from the second location high total values of TPH, PAH and BTEX were detected, while distilled water lecheate is enriched in Hg, AOX, TOC and TPH. This investigation shows that stabilization with lime is not always suitable method for treatment of wastes from petroleum industry, particularly those that are contaminated with both organic and inorganic contaminants. Proper characterization of the waste material to be processed is needed in order to select the most appropriate method of treatment. Our ongoing research study uses different pretreatment techniques and different absorbents (organophilic clay, zeolite, calcined siliceous earth, etc.) to preferentially absorb organic contaminants that can be used before stabilization/solidification.

Abstract:
The produced water from natural gas production process in the North field offshore is considered as the largest wastewater volume in Qatar, which could be potentially used for clean water resources for the industry as well as for some other domestic uses, if it is treated properly. This research aims to study the physical and chemical characterizations of the produced water from the North field and examine the removal of major inorganic and organic pollutants and heavy metals from the PW by using different treatments method such as using the sand filtration, activated carbon filtration and modified activated carbon filtration. The physical and chemical characterization of produced water was examined followed by treatment through sand filtration coupled with activated carbon and microemulsion modified activated carbon techniques. The results of characterization showed that the produced water had high concentration of COD, TOC, BTEX and various metals. After sand filtration, considerable reduction in TSS and COD was achieved. Furthermore, BTEX were also removed by more than 93% except for toluene. However, sand filtration was not enough to remove most of the metals and ions. Therefore, further treatment was done through activated carbon and modified activated carbon and their treatment efficiency was compared. Both techniques were able to achieve higher removal efficiencies for BTEX, metals and ions. Thus, the treated water was free from all major pollutants of PW and can be considered suitable for reuse at industrial application. Further studies and applications could be applied on produced water such as studying the biological characterization and applying biological treatment processes.

Abstract:
Soil is a vital natural resource that regulates our environment sustainability and provide essential resources to humans and nature. Nowadays, with an increasingly populated and urbanized world, pollution is widely recognized as a significant challenge to soil and groundwater resources management. The most common chemicals found in soils and water plumb in a dissolved state and considered as potential pollutants are heavy metals, dyes, phenols, detergents, pesticides, polychlorinated biphenyls (PCBs), and others organic substances, such as organic matter. Unlike organic contaminants, heavy metals are not biodegradable and tend to accumulate in living organisms and many heavy metal ions are known to be toxic or carcinogenic. Toxic heavy metals of particular concern zinc, copper, nickel, mercury, cadmium, lead and chromium. 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 chromium 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−1 was 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. Results proved that the study of chromium mobility revealed the predominance in its transportation through the soil towards the anode, due essentially to the existence of chromium in the form of oxyanions (chromate and dichromate), which confers a negative charge to the molecule. Chromium removal by electrokinetic remediation was faster in low levels of concentration and the utilization of citric acid as buffer and complexing agent allowed to maintain pH of soil below the precipitation limit for this element. It was obtained high removal rates of chromium in both experiments, especially near the anode. In the normalized distance to cathode of 0.8 it was achieved a maximum removal rate of chromium of 55, 59 and 60% in initial chromium concentration of 500 mg kg−1, 250 mg kg−1 and 100 mg kg−1, respectively. The viability of the new coupling technology developed (electrokinetic with EGGIF permeable reactive barrier) to treat low-permeability polluted soils was demonstrated. Based on the proved efficiency, this remediation technique has to be optimized and applied to real soils in order to validate it as a large-scale solution.
