“…This model with sorbed-phase biodegradation and the same Monod kinetic parameters, but unique mass transfer coefficients, provided good predictions for both fast and slow mass transfer regimes within 27.7% of relative error. Kosterin and Sofinskaya (2010) developed a mathematical model for the 1 wt% ntridecane degradation by using biostimulation strategy in an oil-polluted soil. This model includes equations for the diffusion transfer of hydrocarbons and microorganisms into the water phase and the Monod equation for the biodegradation process, and the model was expanded by the hypothesis that the hydrocarbon-oxidizing microorganisms, in the course of their life activity, excrete products whose specific concentrations inhibit the utilization of the hydrocarbon.…”

“…Only few mathematical models that couple mass transfer with Monod or first-order kinetics for hydrocarbon biodegradation are found in the literature (Kosterin and Sofinskaya, 2010;Wang and Vipulanandan, 2001;Woo et al, 2001;), and those models were validated for just one or two bioremediation methodologies; there is no concern about mass transfer of hydrocarbon between NAPL and the gas phases in those models.…”

“…The premise is that more soluble hydrocarbons move from polluted soils to water, leading to additional transport and bioremediation (Fernández et al., 2016; Geng et al., 2014; Nicol et al., 1994). Most models formulated for soils are suitable for ex‐situ bioremediation (Ebenhöh & Berthe‐Corti, 2001; Kosterin & Sofinskaya, 2010; Uzukwu & Dionisi, 2017). Further, several works emphasized mathematical approaches that include mass transfer with Monod or first‐order kinetics, concerning hydrocarbon breakdown, specifically those with relatively less solubility (Park et al., 2001; Woo et al., 2001).…”

In this preliminary research investigation, we introduce a multifactorial approach aimed at optimising the biochemical remediation of petroleum hydrocarbon (PH) polluted soil. The development of these optimisations was determined after solving the equation set. Moreover, we specified the quantitative correlation between the soil treatment aspects and remediation efficiency by the use of real‐world environmental data from the Klaipeda Oil Terminal, Lithuania. The reaction retention time (RTT) and aeration periodicity were the primary aspects affecting soil fertilisation and frequency of microbial addition. Over a two‐month period, remediation efficiency peaked at 99.99%. The study outcomes suggest that the recommended framework may be used to generalise more rapid biochemical degradation of PHs in polluted soil, moving from laboratory‐scale processes to the field (landfill polluted soil) at more than 95% process effectiveness. The accuracy of the formulated framework can be used to arrive at evidence‐based decisions concerning extensive landfill pollution management by estimating contaminant loads and soil‐related treatment aspects.

“…Based on the foregoing, in the present study, we considered kaolinite as a membrane model and tridecane as a model substance transported through this membrane. It should be noted that tridecane, as one of the major petroleum hydrocarbons, is present in wastewaters and soil [ 17 , 18 ] and its removal requires different methods, including membrane technology.…”

Features of Self-Diffusion of Tridecane Molecules in a Porous Medium of Kaolinite Used as a Model of a Chemically Inert Membrane

The present work focused on the experimental study of the specific features of self-diffusion of tridecane molecules in macroporous kaolinite, which is used as a raw material for the production of chemically inert membranes. The measurements of self-diffusion coefficients by pulsed magnetic field gradient nuclear magnetic resonance (PMFG NMR) revealed an increased translational mobility of tridecane molecules in kaolinite with incomplete filling of the pore space. This effect was accompanied by a sharp change in the slope of the Arrhenius plot of the self-diffusion coefficients of tridecane molecules in kaolinite. An analysis of the diffusion spin echo decay in the tridecane–kaolinite system revealed a discrepancy between the experimental data and the theoretical predictions, considering the effect of the geometry of porous space on molecular mobility. It was shown that the experimental results could be interpreted in terms of a model of two phases of tridecane molecules in the pores of kaolinite, in the gaseous and adsorbed state, coexisting under the fast-exchange conditions. Within the framework of the model, the activation energies of self-diffusion were calculated, which agreed satisfactorily with the experimental data. Additionally, the effects of the internal magnetic field gradients arising in a porous medium loaded with a gas or liquid on the data of the PFG NMR measurements were calculated. It was shown that the effect of magnetic field inhomogeneities on the measured self-diffusion coefficients of tridecane in kaolinite is small and could be neglected.
