Development of universal model of kinetics of bioremediation stationary process with substrate inhibition

Development of the mathematical model of the kinetics of the stationary process of bio-cleaning with substratic inhibition

“…Having transcribed expression (1) and replacing the variables, let's obtain a linear multiple regression equation, the determination of the coefficients of which is not difficult. The results of statistical processing prove that the proposed type of dependence for V adequately describes the experimental data [26]. The obtained regression formulas for all the studied processes of biochemical purification are statistically significant by the F-criterion and coefficient of determination R 2 .…”

“…The kinetics modeling technique is based on previously conducted experimental studies of stationary processes of biooxidation of gaseous harmful substances dissolved [15] and not soluble in water [16], as well as contaminations dissolved in water [17]. Equipment and experimental conditions are described in [14][15][16][17][18]. In these works, stationary processes of biochemical destruction were modeled without additional supply of the pollutant during the experiment (a bioreactor of periodic action).…”

Studying the influence of design and operation mode parameters on efficiency of the systems of biochemical purification of emissions

“…The advantages of the presented approach include simplicity of analysis and economic feasibility of the numerical experiment in comparison with the actual industrial experiments which require creation of a pilot facility and significant capital expenditures. Another advantage of the proposed method is that it is based on the mathematical models created with taking into account the results of real experimental data and the ideas of kinetics of methane, hydrogen sulfide and formaldehyde destruction elucidated in laboratory conditions and described earlier in [18][19][20][21][22].…”

“…The previously conducted experimental studies have made it possible to reveal regularities of the biological gas purification process and formulate ideas on the model of microkinetic process [18]. Mathematical models of the processes of biochemical destruction of gaseous soluble [19], insoluble [20] and dissolved in water [21] harmful substances were proposed and a universal model of kinetics of a stationary process of biological purification with a substrate inhibition was presented in [22]. Methods for calculating the design and operation parameters of the systems of biological purification of a corresponding type can be developed based on these models.…”

Development of the mathematical model of the biotreatment process of water-soluble gaseous emissions

“…According to the production data [16], the hydrogen sulfide removal kinetics have been determined. Mathematical descriptions of processes in the trickle-bed biofilter based on statistical evaluation of experimental data [17] and understanding of mass transfer [18] have been performed. The mathematical description of the laboratory stationary biodegradation process adequate for a wide class of pollutants has been proposed in the research [19].…”
