“…After this change, RE ranged between 97.7% and 99.9% and desorption was no longer observable. Figure 5 shows the comparison of toluene EC versus toluene IL obtained in this study and some data close to indoor air conditions from the literature (Moe and Li, 2005;Ondarts et al, 2010a;Tang and Hwang, 1997;Abumaizar et al, 1996;Mathur et al, 2007;Oh et al, 2009;Eldon et al, 2005;Delhoménie et al, 2002;Alvarez-Hornos et al, 2008;Lebrero et al, 2012;Gallastegui et al, 2013).…”

Bioprocesses, such as biofiltration, are commonly used to treat industrial effluents containing volatile organic compounds (VOCs) at low concentrations. Nevertheless, the use of biofiltration for indoor air pollution (IAP) treatment requires adjustments depending on specific indoor environments. Therefore, this study focuses on the convenience of a hybrid biological process for IAP treatment. A biofiltration reactor using a green waste compost was combined with an adsorption column filled with activated carbon (AC). This system treated a toluene-micropolluted effluent (concentration between 17 and 52 µg/m 3 ), exhibiting concentration peaks close to 733 µg/m 3 for a few hours per day. High removal efficiency was obtained despite changes in toluene inlet load (from 4.2 × 10 −3 to 0.20 g/m 3 /hr), which proves the hybrid system's effectiveness. In fact, during unexpected concentration changes, the efficiency of the biofilter is greatly decreased, but the adsorption column maintains the high efficiency of the entire process (removal efficiency [RE] close to 100%). Moreover, the adsorption column after biofiltration is able to deal with the problem of the emission of particles and/or microorganisms from the biofilter.Implications: Indoor air pollution is nowadays recognized as a major environmental and health issue. This original study investigates the performance of a hybrid biological process combining a biofilter and an adsorption column for removal of indoor VOCs, specifically toluene.

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

et al. 2017

View full text Add to dashboard Cite

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.

“…Several treatment methods have been developed to remove those contaminants from industrial wastewater, including ion-exchange, filtration, adsorption and the use of various types of sorbents (Kibazohi et al 2004;Mathur et al 2007;Aivaliotiet al 2012;Almeida et al 2012). Research conducted by scientists around the world on the sorption properties of organo-minerals has proved that zeolites may be an appropriate substance to aid in the sorption of organic compounds (Zhao, Vance 1998;Meininghaus, Prins 2000;Lee, Tiwari 2012;Xie et al 2013;Szala et al 2015;Muir et al 2016a;Bandura et al 2017a).…”

Abstract. The use of zeolites as sorbents has been investigated as a replacement for existing costly methods of removing organic contaminants from water solutions. Zeolites can be modified by inorganic salts, organic surfactants, metals or metal oxides in order to increase their adsorption capacity. The unique ion exchange and adsorption properties of zeolites make them very suitable for application in the removal of organic compounds such as volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), phenols and other complex petrochemicals. Many different studies have demonstrated their effectiveness in reducing the concentrations of organic contaminants as well as petroleum derivatives in water, which has been summarized in this paper.
