Item Analysis of process parameters of wastewater treatment of edible oils production(Видавництво Львівської політехніки, 2017-12-23) Dyachok, Vasyl; Marakhovska, Anastasia; Lviv Polytechnic National UniversityInvestigated the liquid extraction method for possibility to sewage treatment of oils production plants. The mixture of organic solvent (extractant) for selective removal of the main pollutants of wastewater was selected. The resulting equilibrium line and operating line process was obtained. Established transfer steps number. The mathematical model of liquid-extraction wastewater treatment was built. The solution of model allows to predict the kinetics of wastewater extraction for implementing the technology in practice. The equipment to design the flowsheet of liquid extraction method for wastewater treatment of food oils production was matched.Item About problem of absorption of greenhouse gas by chlorophyilsynthesizing microalgae in the presence of sulfur dioxide(Видавництво Львівської політехніки, 2017-12-23) Dyachok, Vasyl; Katysheva, Viktoriia; Lviv Polytechnic National UniversityThe presence of non-competitive reverse inhibition by sulfur dioxide in the process of photosynthesis based on the Lineweaver-Burk theory was theoretically justified and experimentally proved. The mathematical description of the growth of the cells of the microalgae is given and as a result of processing experimental data the growth rates of the algae at certain values of inhibitor concentration was defined. Based on the obtained values the analytical dependence of growth rate of biomass from the substance of inhibitor was redused. The maximum value of concentration of sulphur dioxide which may occur photosynthesis and biomass growth of microalgae was set.
