“…Lanthier et al ( 2000 ) had reported augmentation of dehalorespiring strains ( Desulfi tobacterium dehalogenans and Desulfi tobacterium frappieri ) that used organo-chlorinated materials as electron acceptors in slurry bioreactors. Nano et al ( 2003 ) recommended the combined application of slurry and solid phase bioreactor systems to remediate diesel-contaminated soils along with the use of soil additives, sand and surfactants for rapid TPH degradation (>95 %) in a week. estimated the effect of co-substrates (molasses and starch) in anaerobic slurry-phase biological degradation of TNT and reported 87-97 % degradation, which was 50-60 % higher than contaminant degradation without co-substrate addition.…”

Pollution and the global health impacts from toxic environmental pollutants are presently of great concern. At present, more than 100 million people are at risk from exposure to a plethora of toxic organic and inorganic pollutants. This review is an exploration of the ex-situ technologies for cleaning-up the contaminated soil, groundwater and air emissions, highlighting their principles, advantages, deficiencies and the knowledge gaps. Challenges and strategies for removing different types of contaminants, mainly heavy metals and priority organic pollutants, are also described.

Partly due to the complex and variable composition of oily sludge generated by the petroleum industry, cost-effective treatment and proper disposal pose considerable challenges worldwide. In this study, an extended component-based analysis of the oily sludge from a fl occulation-fl otation unit of a wastewater treatment system in a refi nery in Sweden was carried out over 1 year. The heterogeneity of the oily sludge is illustrated by the wide ranges of concentrations found for different chemical components, particularly metals. Among the petroleum hydrocarbons, the most abundant compounds were nonpolar aliphatic hydrocarbons (63.7 ± 16.7 g kg −1 ); from the benzene, toluene, ethylbenzene, and xylene group, xylenes (91-240 mg kg −1 ) were most abundant; and among polycyclic aromatic hydrocarbons, naphthalene (25.7 ± 21.4), fl uorene (27.25 ± 10.0), and phenanthrene (43.8 ± 18.4 mg kg −1 ) were most abundant (all results in terms of dry matter). Based on the EU guidelines and the mean concentration values for metals found in the oily sludge, e.g., Pb (135.4 ± 125.8), Cu (105.2 ± 79.1), Hg (42.8 ± 31.3), Ni (320 ± 267.4), and Zn (1321.7 ± 529.9 mg kg −1 ), disposal of oily sludge even in landfi lls for hazardous waste is not allowed. The organic content of the sludge can be reduced through biotreatment, but not the metal content. A multistep component-based treatment scheme is therefore needed.The oily sludge generated at fl occulation-fl otation units (FFU sludge) of wastewater treatment plants contains J Mater Cycles Waste Manag (2008) 10:79-86
