Crude Oil Degradation on the Influence of Palm oil-Fermented Wastewater Used as Biostimulant
Abstract: *Author for CorrespondenceUkpaka Chukwuemeka Peter E-mail: [email protected] The total petroleum hydrocarbon (TPH) degradation was monitored in a batch reactor with the addition of biostimulants like palm oil processed wastewater (POPWW) acting as nutrients, to effectively enhance high efficiency in contaminants remediation in clay soil. The kinetic components were evaluated in terms of specific rates of petroleum hydrocarbon degradation, maximum specific rate of total petroleum hydrocarbon degradation as well as the …

Evaluation of Treatment Performance in TPH Removal from Soil: A Comparative Study of Baobab and Neem Treatments
Abstract: This study evaluates the effectiveness of Baobab (Adansonia) and Neem (Azadirachta indica) in powdered form, combined with yeast and NPK fertilizer, for the bioremediation of Total Petroleum Hydrocarbons (TPH) in polluted swampy and clay soils. Over an 84-day period, both treatments significantly enhanced TPH degradation, with Neem showing slightly better performance overall. In swampy soil, TPH removal ranged from 97.78% (Baobab) to 98.50% (Neem), while in clay soil, it ranged …

Modeling the Biokinetic of Crude Oil Degradation inLoamy Soil Using the Citrus Sinensis of Flavedo Part
Abstract: The biokinetic parameters of crude oil degradation using Citrus sinensis of flavedo part was investigated in loamy soil environment. Mathematical models were developed for the purpose of determining the biokinetic parameters of the k1 (Total Petroleum Hydrocarbon), maximum specific rate of TPH remediation and dissociation constant of the TPH remediation on the effect of remediant dosage on the polluted loamy soil environment. The effect of the remediants were monitored for …

Investigation on the Characteristics of Chromolaena Odorata (Awolowo leaf) in Petroleum Hydrocarbon Degradation in Loamy Soil Environment
Abstract: The application of Chromolaena odorata (Awolowo leaf), processed into powder form, was used as a biostimulant for petroleum hydrocarbon degradation and mitigation in a loamy soil environment. In this investigation, the physicochemical and microbial characteristics of the sample were determined, as presented in this research, including pH, electrical conductivity (EC), total nitrogen (T.N), total phosphorus (T.P), potassium (K), total organic carbon, and P. fluorescence. Corynebacterium sp., Arthrobacter, Bacillus, Acinetobacter iwoffi, …

Computation of Biokinetic Parameters of Total Petroleum Hydrocarbon Degradation using Vernonia amygdalina Stem
Abstract: This investigation showcases the computation of biokinetic parameters of total petroleum hydrocarbon degradation using Vernonia amygalina stem as bio-stimulant for the remediation of contaminants in loamy soil environment. The research revealed decrease in TPH degradation with increase in contact time and the percentage reduction was computed. The result shows TPH (100 dosage) > TPH (75g dosage) > TPH (50g dosage) > TPH (25g dosage) > TPH (control sample) and the …

Experimental Study on Effect of Momentum Transfer Hydrocarbon Degradation in Stream System
Abstract: This research work demonstrates the significance of individual hydrocarbon degradation in a flowing stream system and the effect of the momentum transfer on the concentration of the individual hydrocarbon was examined on the influence of period of exposure (time) on the environment as well as the distance of dispersion. The substrate concentration variation was monitored with respect to time and distance as well as reciprocal of the substrate established by …
