Application of Mineral Sorbents for Removal of Petroleum Substances: A Review

Environmental pollution with petroleum products has become a major problem worldwide, and is a consequence of industrial growth. The development of sustainable methods for the removal of petroleum substances and their derivatives from aquatic and terrestrial environments and from air has therefore become extremely important today. Advanced technologies and materials dedicated to this purpose are relatively expensive; sorption methods involving mineral sorbents are therefore popular and are widely described in the scientific literature. Mineral materials are easily available, low-cost, universal adsorbents and have a number of properties that make them suitable for the removal of petroleum substances. This review describes recent works on the use of natural, synthetic and modified mineral adsorbents for the removal of petroleum substances and their derivatives from roads, water and air.

“…The slow degradation rates may be attributed to oxygen and nutrient deficiency (no additional nutrients were added to balance the C:N:P-ratio after the addition of the carbon rich diesel). Chagas-Spinneli, Kato et al (2012) reported that aeration had a stronger effect on diesel PAH degradation in soil than addition of nutrients and microorganisms by the end of a 129-day experiment in a comparable tropical clay soil (oxisol). Deficient oxygen levels due to restricted diffusion of gases through soil pores in the dense clay soil may have been a contributing factor to the slow degradation rate together with nutrient deficiency.…”

“…Other reasons for the slow degradation rates may include reduced bioavailability of the diesel due to sorption of diesel fuel hydrocarbons to organic matter and especially clay particles in the soil matrix (Alexander, 1999;Chagas-Spinelli et al, 2012). Microcosm experiments showed Linnaeus ECO-TECH ´14 Kalmar, Sweden, November 24-26, 2014 that degradation of hexadecane (a typical diesel fuel hydrocarbon) was considerably slower in a loamy sand (silt and clay 18.6 %) compared to a sand (silt and clay 3.2 %) after treatment of the diesel fuel contaminated soils with fermented whey (Östberg, Jonsson, & Lundström, 2007).…”

“…The high yearly average soil temperatures in tropical regions makes implementation of in-situ soil bioremediation particularly interesting, especially in contaminated areas of little economic value where remediation would not be implemented with more expensive methods. One obstacle is that many tropical soils have a high clay content (Chagas-Spinelli, Kato, de Lima, & Gavazza, 2012) which might decrease the bioavailability of the pollutant and thus obstruct the degradation (Ferguson et al, 2003).…”

Organic by-products for sustainable soil remediation -the effect of 3 different amendments on the degradation of diesel fuel in a tropical ultisol

In many tropical developing countries, economic incentives are small for soil remediation to take place. Such locations demand special strategies that are energy-efficient, locally adapted and economic. In situ technologies are appealing where energy and material costs are more limiting than the time factor. One potentially sustainable and economic way to enhance the self-organizing capacity of soil ecosystems is by applications of locally available organic byproducts to stimulate the polluted ecosystem´s inherent capacity to heal by utilising the embodied energy of the organic pollutant itself, as an energy source for the necessary biochemical transformations. Tropical climate is favourable for biodegradation but many tropical soils are rich in clay which can inhibit the bioavailability of the pollutant and reduce biodegradation kinetics. A pilot scale experiment was performed in order to assess the capability of three amendments based on by-products; whey, pyroligneous acid and compost tea, to enhance degradation of diesel in ultisol. Biweekly applications of 6 mL whey kg -1 soil significantly increased the degradation rate but no positive effect on degradation was found of any of the other amendments.

“…Numerous bacterial strains capable of existing in soils contaminated with PAHs have been isolated and characterized (Zhang et al 2004;Abd-Elsalam et al 2009;Mao et al 2012;Muangchinda et al 2013). Several researchers have used the help of microbes to remediate diesel oil contaminated soil (Wang et al 1990;Penet et al 2004;Chagas-Spinelli et al 2012;Silva-Castro et al 2013;Vázquez et al 2013) and manufactured gas plant site soil (Hawthorne and Grabanski, 2000). Comparison of various field and laboratory methods in bioremediation process of PAHs-contaminated soil has also been carried out by many researchers (Lors et al 2012;Moscoso et al 2012;Lladó et al 2013).…”

The present study was carried out with the objective of integrating physical and biological methods for the treatment of polycyclic aromatic hydrocarbons (PAHs)-contaminated groundwater and to assess its efficiency. The aquifer in Kirchseeon region, Germany, is contaminated with PAHs due to product loss of tar oil which was used in large amounts for treating the railway sleepers produced in this area. Six pumping wells, two recharge wells and fifteen observation wells were installed for this study as a part of the ex situ biodegradation treatment plant. Zoogloea, Leptothrix, Sphingomonas, Novosphingobium and Comamonadaceae were the indigenous bacteria that facilitated degradation of the PAHs. In the bioreactors, 95 % of naphthalene and methylnaphthalene and 90 % of total PAHs were removed. During this remediation process, 700,000 m 3 of PAHs-contaminated groundwater was purified to almost drinking water quality. Also, 7,000 kg of dense non-aqueous phase liquid (DNAPL) and 950 kg of PAHs were removed from the pumped groundwater. The remediated groundwater is recharged back into the aquifer through two recharge wells located 600 m from the study site. The observation wells show a decrease in contamination of up to 95 %. Thus, this field scale study showed that using indigenous bacteria to remediate PAHs-contaminated groundwater is a viable option.
