Kinetic Modelling and Half Life Study of Adsorptive Bioremediation of Soil Artificially Contaminated With Bonny Light Crude Oil

Statistical optimization and kinetic studies of enhanced bioremediation of crude oil - contaminated marine water using combined adsorption-biostimulation strategy

“…This observation indicates that the presence of commercial activated carbon enhanced the TPH reduction in crude oil-contaminated marine water. Similar observations have been reported for the use of activated carbon/activated charcoal in the bioremediation of soil and sediment contaminated with petroleum hydrocarbon/crude oil (Semenyuk et al, 2014;Agarry et al, 2015). The observed enhancement may be as a result of the fact that the applied activated carbon performed the task of adsorbing oil as well as providing a matrix for oildegrading microorganisms while at the same time improved the oxygen, nutrient and hydrocarbon mass transfer in the marine water (Gertler et al, 2009).…”

“…However, combined method of adsorption and bioremediation is in recent time gaining attention as a means of remediation referred to as adsorptive bioremediation . The addition of activated carbon (AC) as well as biochar is currently being investigated as an in situ technology to remediate contaminated soil and sediments (Ghosh et al, 2011;Meynet et al, 2012;Agarry et al, 2015). Nevertheless, information on the effective use of nutrients, surfactants and adsorbent as amendment agents in the remediation of oil-contaminated marine/seawater (open systems) is still very scanty and the literature is still inconclusive on the amendment agents' conditions that are sufficient for different environment.…”

Evaluation of the effects of inorganic and organic fertilizers and activated carbon on bioremediation of soil contaminated with weathered crude oil

“…At 5% (w/w) WECO concentrations, run numbers 2 and 4, and runs number 11 and 12 had same remediation condition with different dosage of activated carbon; results shows that addition of activated carbon can enhance crude oil removal. Similar observations have been reported for the use of activated carbon in the remediation of environment contaminated with herbicide propanil (3',4'-dichloropropionanilide) in the Krasnodar region of Russia, 3,4-dichloroaniline, polychlorinated biphenyls (PCB), 2,4,6-trinitrotoluene (TNT) (Vasilyeva et al, 2010), anthracene (Owabor and Aluyor, 2008), diesel fuel (Semenyuk et al, 2014) and crude oil (Agarry et al, 2015). Effect of different amount of organic fertilizer (cattle dung + pig dung+ poultry droppings) on TPH biodegradation were investigated at the same condition of inorganic NPK fertilizer and activated carbon (run numbers 6 and 8, and run numbers 10 and 12) and the results showed that addition of organic fertilizer (cattle dung + pig dung + poultry droppings) can enhance the bioremediation process of soil contaminated with crude oil.…”

“…This problem often restricts its use for highly contaminated soils (Vasilyeva et al, 2010, Meynet et al, 2012Agarry et al, 2015). Activated or non-activated charcoals have been shown to reduce contaminant uptake from soil by plants (Vasilyeva et al, 2010;Jakob et al, 2012).…”

Biodegradation of total petroleum hydrocarbons from acidic sludge produced by re-refinery industries of waste oil using in-vessel composting

“…In this study kinetic analysis as an important factor for degradation of TPH removal is based on first and second orders were studied. In the previous studies kinetic modeling for hydrocarbon biodegradation has been described [ 49 – 53 ]. The information on kinetic of TPH biodegradation by in-vessel composting is so important because the remaining concentration of contaminant can be identified at any time and on the other hand prediction of the process would be done with kinetic analysis.…”
