“…Contaminant removals observed in such a short remediation time are hardly achievable by other treatments, especially if they are bioprocess-based. In this case, diesel removal values not higher than about 80% and remediation times of up to 300 days were observed by several authors (Fern andez et al, 2011;Łebkowska et al, 2011;Li et al, 2007;Liu et al, 2013). More recently, Szulc et al (2014), in a study focused on assessing the influence of bioaugmentation and the addition of rhamnolipids on contaminant biodegradation during field studies of extended length (365 days), reported a maximum diesel removal of about 85%.…”

Aquifer contamination with diesel fuel is a worldwide environmental problem, and related available remediation technologies may not be adequately efficient, especially for the simultaneous treatment of both solid and water phases. In this paper, a lab-scale 2.45 GHz microwave (MW) treatment of an artificially diesel-contaminated aquifer was applied to investigate the effects of operating power (160, 350 and 500 W) and time on temperature profiles and contaminant removal from both solid and water phases. Results suggest that in diesel-contaminated aquifer MW remediation, power significantly influences the final reachable temperature and, consequently, contaminant removal kinetics. A maximum temperature of about 120 °C was reached at 500 W. Observed temperature values depended on the simultaneous irradiation of both aquifer grains and groundwater. In this case, solid phase heating is limited by the maximum temperature that interstitial water can reach before evaporation. A minimal residual diesel concentration of about 100 mg kg(-1) or 100 mg L(-1) was achieved by applying a power of 500 W for a time of 60 min for the solid or water phase, respectively. Measured residual TPH fractions showed that MW heating resulted in preferential effects of the removal of different TPH molecular weight fractions and that the evaporation-stripping phenomena plays a major role in final contaminant removal processes. The power low kinetic equation shows an excellent fit (r(2) > 0.993) with the solid phase residual concentration observed for all the powers investigated. A maximum diesel removal of 88 or 80% was observed for the MW treatment of the solid or water phase, respectively, highlighting the possibility to successfully and simultaneously remediate both the aquifer phases. Consequently, MW, compared to other biological or chemical-physical treatments, appears to be a better choice for the fast remediation of diesel-contaminated aquifers.

“…£ebkowska et al [38] found an 80% removal of TPH for a sandy soil polluted by diesel at 5300 mg kg −1 of TPH treated by ex situ biopile remediation for a period of about 2 months. Sprocati et al [39] carried out a study on bioaugmentation aimed at the remediation of a soil co-contaminated (spiked) with both diesel oil and heavy metals, using microcosms in different experimental conditions.…”

In this study, the remediation of diesel-polluted soils was investigated by simulating an ex situ microwave (MW) heating treatment under different conditions, including soil moisture, operating power and heating duration. Based on experimental data, a technical, energy and economic assessment for the optimization of full-scale remediation activities was carried out. Main results show that the operating power applied significantly influences the contaminant removal kinetics and the moisture content in soil has a major effect on the final temperature reachable during MW heating. The first-order kinetic model showed an excellent correlation (r2 > 0.976) with the experimental data for residual concentration at all operating powers and for all soil moistures tested. Excellent contaminant removal values up to 94.8% were observed for wet soils at power higher than 600 W for heating duration longer than 30 min. The use of MW heating with respect to a conventional ex situ thermal desorption treatment could significantly decrease the energy consumption needed for the removal of hydrocarbon contaminants from soils. Therefore, the MW treatment could represent a suitable cost-effective alternative to the conventional thermal treatment for the remediation of hydrocarbon-polluted soil.

“…In cases of accidental burst of the oil pipe, VOCs diffuse through the pore space of the soil into the atmosphere and cause both soil and air pollution. Research on soil pollution was proposed for identification of the hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) after pollution (Lebkowska et al, 2011;Sun et al, 2013;Yu et al, 2012). Besides, during the pollution process, the amount of VOCs adsorbed to soil and the rate of diffusion from soil into the atmosphere present an interesting subject, which may provide scientific evidence for remote detection of oil spills using adapted light detection and ranging (LIDAR) systems (Fix et al, 2004).…”
