    Abstract [en]

    A wide diversity of physical and chemical processes control the distribution of species in waters in the vadose zone above the water table, and in the saturated zone below. The mineralogical composition of rocks or sediments, chemical reactions between solid, aqueous and gas phases, and oxidation/reduction (redox) processes are principal factors that influence the chemical composition of vadose-zone, ground-and surface waters, and the concentrations and mobilities of individual species.

    Coupling geothermal direct heat with agriculture2018Ingår i: Geothermal Water Management, CRC Press, 2018, s. 277-300Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    In the agriculture and agri-food chain industries there is a strong nexus between food, energy and water as it consumes about one-third of the global energy and 80-90% of the world’s freshwater production; freshwater production consumes about 15% of the global energy production (FAO, 2011a, 2011b; Hoff, 2011; IEA, 2012; IRENA, 2015). Therefore, the agri-food chain should be made independent from the use of fossil fuels, which have decreasing and fluctuating reserves but increasing long-term trend in cost, by coupling it to renewable energies such as geothermal. Geothermal water can not only provide energy, but at the same time a source of freshwater (possibly requiring prior treatment, that can, in turn, be done using geothermal heat as the energy source) thereby providing secure, accessible and environmentally sustainable supplies for both of these commodities. It can therefore play a significant role in contributing to future global food security and climate protection as well as other aspects of the Sustainable Development Goals (SDGs). The benefits of using geothermal energy are often underestimated, despite it being a limitless, sustainable and constant heat source, available 24 hours a day, 365 days a year. This makes its use technically simple, which contrasts with other renewables such as solar energy. Development and commercialization of geothermal water as energy and freshwater sources could have a significant contribution in the reduction of costs in the agro-food sector. However, much work remains to be done to make better use of geothermal energy.

    Geochemical modeling of groundwater, vadose and geothermal systems2011Bok (Övrigt vetenskapligt)
    Abstract [en]

    Geochemical modeling is an important tool in environmental studies, and in the areas of subsurface and surface hydrology, pedology, water resources management, mining geology, geothermal resources, hydrocarbon geology, and related areas dealing with the exploration and extraction of natural resources. The book fills a gap in the literature through its discussion of geochemical modeling, which simulates the chemical and physical processes affecting the distribution of chemical species in liquid, gas, and solid phases. Geochemical modeling applies to a diversity of subsurface environments, from the vadose zone close to the Earth's surface, down to deep-seated geothermal reservoirs. This book provides the fundamental thermodynamic concepts of liquid-gas-solid phase systems. It introduces the principal types of geochemical models, such as speciation, reaction-path or forward, inverse- and reactive-transport models, together with examples of the most common codes and the best-practices for constructing geochemical models. The physical laws describing homogeneous and heterogeneous chemical reactions, their kinetics, and the transport of reactive solutes are presented. The partial differential or algebraic equations representing these laws, and the principal numerical methods that allow approximate solutions of these equations that can provide useful solutions to model different geochemical processes, are discussed in detail. Case studies applying geochemical models in different scientific areas and environmental settings, conclude the book. The book is addressed to students, teachers, other professionals, and to the institutions involved in water, geothermal and hydrocarbon resources, mining, and environmental management. The book should prove useful to undergraduate and graduate students, postgraduates, professional geologists and geophysicists, engineers, environmental scientists, soil scientists, hydrochemists, and others interested in water and geochemistry.

    Desalination of salty water using vacuum spray dryer driven by solar energy2017Ingår i: Desalination, ISSN 0011-9164, E-ISSN 1873-4464, Vol. 404, s. 182-191Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper addresses evaporation under vacuum condition with the aid from solar energy and the recovered waste heat from the vacuum pump. It is a preliminary attempt to design an innovative solar-based evaporation system under vacuum. The design details, equipment required, theoretical background and work methodology are covered in this article. Theoretically, based on the energy provided by the sun during the day, the production rate of pure water can be around 15 kg/m2/day. Assumptions were made for the worst case scenario where only 30% of the latent heat of evaporation is recycled and the ability of the dark droplet to absorb sun energy is around 50%. Both the waste heat from the pump and the heat collected from the photovoltaic (PV) panels are proposed to raise the temperature of the inlet water to the system to its boiling point at the selected reduced pressure.

    Arsenic removal by small-scale reverse osmosis units2010Ingår i: The Global Arsenic Problem: Challenges for Safe Water Production, CRC Press , 2010, s. 147-156Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    Over the past three decades, the occurrence of high concentrations of arsenic (As) in drinking water has been recognized as a severe global public-health concern (Bhattacharya et al. 2002, Mandal and Suzuki 2002, Ng et al. 2003). The global As-contamination scenario has changed considerably in recent years, with the discovery of new As affected sites. The delayed health effects of exposure to As, the lack of common definitions and of local awareness, as well as poor reporting in affected areas are all major problems in determining the extent of the arsenic-in-drinking-water problem (WHO 2008).

    The Taiwan crisis: A showcase of the global arsenic problem2010Bok (Övrigt vetenskapligt)
    Abstract [en]

    In the 1950s, the residents of the southwestern coastal areas of Taiwan suffered greatly from Blackfoot disease (BFD) due to the consumption of arsenic-contaminated groundwater. Groundwater with high levels of arsenic in southwestern and northeastern Taiwan received much attention. After arsenic-safe tap water was utilized for drinking instead of groundwater in the 1970s, BFD cases decreased greatly. After 1990, no new BFD cases were reported, and as a consequence, BFD problems disregarded. However, arsenic is still present in the groundwater.This book will improve the knowledge and understanding of the occurrence and genesis of arsenic-rich groundwaters in Taiwan. It deals with constraints on the mobility of arsenic in groundwater, its uptake from soil and water by plants, arsenic-propagation through the food chain, human health impacts, and arsenic-removal technologies. Taiwan case experiences are described in this book and can be applied worldwide. This book is a state-of-the-art overview of research on arsenic in Taiwan and is designed to: • create interest in regions within Taiwan that are affected by the presence of arseniferous aquifers; • draw attention from the international scientific community; • increase awareness among researchers, administrators, policy makers, and company executives; • improve the international cooperation on arsenic problems worldwide.

    A critical overview of renewable energy technologies for desalination2017Ingår i: Renewable Energy Technologies for Water Desalination, CRC Press , 2017, s. 1-12Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    Rapid population growth and industrialization as well as climatic change have placed increasing strains on global potable water supplies (Caldera et al., 2016; Goosen et al., 2016; Sahin et al., 2016). In particular, the demand for this limited renewable resource is anticipated to intensify due to the requirements of the agricultural, manufacturing and urban sectors. The United Nations World Water Assessment Programme estimates that by 2030 only 60% of the worldwide water needs can be met (Connor, 2015). Additionally, while economic development opens up and advances economies, and creates new wealth, it can be argued that millions of people do not benefit directly from this financial progress (Goosen, 2013; Gottinger and Goosen, 2012). This poses new challenges to the effective governance of potable water resource systems.

    Removal of fluoride from water through bacterial-surfactin mediated novel hydroxyapatite nanoparticle and its efficiency assessment: Adsorption isotherm, adsorption kinetic and adsorption Thermodynamics2018Ingår i: Environmental Nanotechnology, Monitoring and Management, ISSN 2215-1532, Vol. 9, s. 18-28Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Fluoride contamination in water due to natural and anthropogenic activities has been documented as serious problems worldwide commanding a major threat to the environment. Present study focuses to synthesis bacterial-surfactin (Bacillus subtilis) mediated nano-hydroxyapatite (HAp), novel adsorbents for defluoridation. HAp particle size and morphology were controlled by varying temperature of 90–150 °C and pH of 7–11, respectively. The TEM and SEM micrographs reveal that the short-rod particle is observed 20–30 nm at 90 °C and pH 11. The ratio between the length (nm) and width (nm) of nanoparticle are decreased from 4.17 to 1.65 with increasing pH (7–11). The selected area diffraction (SAD) of particles are indicated uniform rod-like monocrystals. The XRD and FTIR observations were indicated the synthesized HAp nanoparticles were well-crystallized with purity phase and high quality. The study reflected that the fluoride removal from contaminated water by HAp was increased significantly (R2 = 99) with the increasing adsorbent concentration, temperature and time, with two-step adsorption process as the first portion a rapid adsorption occurs during first 90 min after which equilibrium is slowly achieved. The adsorption process is closer to Freundlich isotherm (R2 > 98) than to Langmuir isotherm (R2 ≈ 92), indicating HAp as a good adsorbent (n > 3). Above 97% of fluoride removal were noticed at a HAp dose of 0.06 g/10 mL. The adsorption kinetics more fit with pseudo-second-order (R2= 99) in compare to pseudo-first-order (R2 ≈ 91). The slope and intercept of Arrhenius equation indicated the activation/adsorption energy (Ea) of 3.199 kJ/mol and frequency factor (A) of 1.78 1/s. Adsorption thermodynamic parameters (free energy (ΔG < 0), enthalpy (ΔH > 0) and entropy (ΔS > 0)) indicates the spontaneous and endothermic reactions of the adsorption process. Thus, newly synthesized HAp nanoparticles exhibit as a good adsorbent for fluoride removal, theoretically and experimentally being applicable for environmental pollution control.

    Microalgae for third generation biofuel production, mitigation of greenhouse gas emissions and wastewater treatment: Present and future perspectives - A mini review2014Ingår i: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 78, s. 104-113Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The extensive use of fossil fuels is increasingly recognized as unsustainable as a consequence of depletion of supplies and the contribution of these fuels to climate change by GHG (greenhouse gas) emissions into the atmosphere. Microalgae indicate alternative renewable sustainable energy sources as they have a high potential for producing large amounts of biomass which in turn can be used for production of different third-generation biofuels at large scale. Microalgae transform the solar energy into the carbon storage products, leads to lipid accumulation, including TAG (triacylglycerols), which then can be transformed into biodiesel, bioethanol and biomethanol. This paper reviews the selection, production and accumulation of target bioenergy carrier's strains and their advantages as well as the technological development for oil, biodiesel, ethanol, methanol, biogas production and GHG mitigation. The feedstock of promising algal strain exhibits the suitable biofuel production. The current progress of hybrid-technologies (biomass production, wastewater treatment, GHG mitigation) for production of prime-products as biofuels offer atmospheric pollution control such as the reduction of GHG (CO2 fixation) coupling wastewater treatment with microalgae growth. The selection of efficient strain, microbial metabolism, cultivation systems, biomass production are key parameters of viable technology for microalgae-based biodiesel-production.

    Geothermal arsenic in Taiwan: Geochemistry and microbial diversity2012Ingår i: UNDERSTANDING THE GEOLOGICAL AND MEDICAL INTERFACE OF ARSENIC, AS 2012 / [ed] Ng, JC Noller, BN Naidu, R Bundschuh, J Bhattacharya, P, CRC PRESS-TAYLOR & FRANCIS GROUP , 2012, s. 483-485Konferensbidrag (Refereegranskat)
    Abstract [en]

    This study describes the fluid chemical compositions and related microbial diversity in geothermal systems of Taiwan. The fluid samples were collected from several geothermal springs located in northern and southern Taiwan. The pH values of the fluids showed diverse character of the geothermal systems, some are acidic in nature while few showed alkaline in nature. The fluids also contain high arsenic concentrations with As(III) as the dominant species. Yang-Ming-Shan and Beitou hot springs in northern Taiwan were characterized by sulfur spring type (contains H-SO4). The 16S rRNA gene sequence of microbial community indicated the presence of thiosulfate-oxidizing, alkaliphilic, psychrotolerant and chemo-organoheterotrophy bacterium such as Limnobacter thiooxidans, Clostridium sulfidigenes and Desulfovibrio psychrotolerans, respectively.

    Photocatalytic activity and synthesis procedures of TiO2 nanoparticles for potential applications in membranes2017Ingår i: Application of Nanotechnology in Membranes for Water Treatment, CRC Press , 2017, s. 127-146Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    Heterogeneous photocatalysis based on oxide semiconductors is a promising technique for the prevention of microbial proliferation and to limit the growth of microorganisms. Among the studied photocatalysts, titanium dioxide (TiO2) represents one of the most interesting materials, due to its low cost, biocompatibility, chemical and thermal stability, and notable optical and dielectric properties. It exists in three polymorphic forms: rutile, which is the most stable form, anatase and brookite, both of which are metastable and convert into rutile upon heating. TiO2 nanoparticles can be efficiently obtained via different synthesis techniques, such as sol-gel, sol, hydrothermal, solvothermal, direct oxidation, chemical or physical vapor deposition, microwave, and reverse micelle methods, which offer the possibility to obtain well-controlled nanoparticle size and morphology. In the different TiO2 applications, its antimicrobial action has attracted a lot of attention in the last few decades. Particularly promising are the hybrid or mixed matrix TiO2- polymeric membranes, which allow separation and simultaneous photocatalytic reaction, without requiring any catalyst recovery operation. Several works have been published on the efficiency of the hybrid inorganic-organic membranes as antimicrobial systems, for bacteria, viruses, fungi and algae disruption. The TiO2 incorporation in/on the polymeric membrane also allows the reduction of fouling and at the same time highly improves water permeability and self-cleaning ability.

    Arbuscular mycorrhizal fungi-assisted phytoremediation of a lead-contaminated site2016Ingår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 572, s. 86-97Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Knowledge of the behavior of plant species associated with arbuscular mycorrhizal fungi (AMF) and the ability of such plants to grow on metal-contaminated soils is important to phytoremediation. Here, we evaluate the occurrence and diversity of AMF and plant species as well as their interactions in soil contaminated with lead (Pb) from the recycling of automotive batteries. The experimental area was divided into three locations: a non-contaminated native area, a coarse rejects deposition area, and an area receiving particulate material from the chimneys during the Pb melting process. Thirty-nine AMF species from six families and 10 genera were identified. The Acaulospora and Glomus genera exhibited the highest occurrences both in the bulk (10 and 6) and in the rhizosphere soils (9 and 6). All of the herbaceous species presented mycorrhizal colonization. The highest Pb concentrations (mg kg− 1) in roots and shoots, respectively, were observed in Vetiveria zizanoides (15,433 and 934), Pteris vitata (9343 and 865), Pteridim aquilinun (1433 and 733), and Ricinus communis (1106 and 625). The diversity of AMF seems to be related to the area heterogeneity; the structure communities of AMF are correlated with the soil Pb concentration. We found that plant diversity was significantly correlated with AMF diversity (r = 0.645; P > 0.05) in areas with high Pb soil concentrations. A better understanding of AMF communities in the presence of Pb stress may shed light on the interactions between fungi and metals taking place in contaminated sites. Such knowledge can aid in developing soil phytoremediation techniques such as phytostabilization.

    Potential of different AM fungi (native from As-contaminated and uncontaminated soils) for supporting Leucaena leucocephala growth in As-contaminated soil2017Ingår i: Environmental Pollution, ISSN 0269-7491, E-ISSN 1873-6424, Vol. 224, s. 125-135Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Arbuscular mycorrhizal (AM) fungi inoculation is considered a potential biotechnological tool for an eco-friendly remediation of hazardous contaminants. However, the mechanisms explaining how AM fungi attenuate the phytotoxicity of metal(oid)s, in particular arsenic (As), are still not fully understood. The influence of As on plant growth and the antioxidant system was studied in Leucaena leucocephala plants inoculated with different isolates of AM fungi and exposed to increasing concentrations of As (0, 35, and 75 mg dm−3) in a Typic Quartzipsamment soil. The study was conducted under greenhouse conditions using isolates of AM fungi selected from uncontaminated soils (Acaulospora morrowiae, Rhizophagus clarus, Gigaspora albida; and a mixed inoculum derived from combining these isolates, named AMF Mix) as well as a mix of three isolates from an As-contaminated soil (A. morrowiae, R. clarus, and Paraglomus occultum). After 21 weeks, the activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR) were determined in the shoots in addition to measuring plant height and mineral contents. In general, AM fungi have shown multiple beneficial effects on L. leucocephala growth. Although the activity of most of the stress-related enzymes increased in plants associated with AM fungi, the percentage increase caused by adding As to the soil was even greater for non-mycorrhizal plants when compared to AM-fungi inoculated ones, which highlights the phytoprotective effect provided by the AM symbiosis. The highest P/As ratio observed in AM-fungi plants, compared to non-mycorrhizal ones, can be considered a good indicator that the AM fungi alter the pattern of As(V) uptake from As-contaminated soil. Our results underline the role of AM fungi in increasing the tolerance of L. leucocephala to As stress and emphasize the potential of the symbiosis L. leucocephala-R. clarus for As-phytostabilization at moderately As-contaminated soils.

    Abstract [en]

    The paper presents an innovative approach to freshwater production using geothermal aquifers as a water and energy source. The main parameters which can potentially influence the results of the analysis were selected to investigate their effect on the proposed schemes, e.g. feed water quality, quality of the geothermal resource, concentrate utilisation and cost of freshwater production. A technical and economic feasibility study demonstrates that effective use of geothermal resources can include direct utilisation of geothermal energy in the heating system and the use of the cooled water as a source of freshwater obtained in a desalination unit. The comparison of the costs of freshwater from current freshwater resources in Poland (groundwater and surface water) with those calculated for the geothermal option showed that the costs of the latter are equal to the former. The treatment of geothermal water can bring an improved water balance for drinking purposes. In areas of high water deficit, the solution presented is a good example of the rational management of geothermal resources.
