    To the problems of wastewater treatment from mineral pollutants with the use of microalgae
    (Видавництво Львівської політехніки, 2021-03-03) Dyachok, Vasil; Mandryk, Solomiia; Huhlych, Serhiy; Lviv Polytechnic National University
    This article presents the results of experimental studies on the use of Chlorella microalgae for wastewater treatment from the most common mineral pollutants. The influence of the mineral pollutants, namely anions HSO , NO , H PO on the dynamics of wastewater treatment has been established. Analytical dependences of microalgae biomass growth rate depending on pollutant concentration HSO , NO and H PO are obtained. The values of biomass growth coefficients at the corresponding pollutant concentrations are determined. Based on the obtained experimental research results, mathematical models have been constructed that allow predicting the maximum values of mineral pollutants concentrations at which effective wastewater treatment by chlorophyllsynthesizing microalgae is possible. The technological scheme of wastewater treatment from mineral pollutants and the mechanism of the obtained application biomass are proposed.

    Activator of carbon dioxide absorption by chlorophyll-synthesizing microalgae
    (Lviv Politechnic Publishing House, 2019-02-26) Dyachok, Vasil; Mandryk, Solomiia; Huhlych, Serhiy; Lviv Polytechnic National University
    The influence of nitrogen oxides on the СО2 uptake rate by chlorophyll-producing microalgae of Chlorella type was investigated. Experimental dependences of microalgae concentration growth over time under certain values of nitrogen oxides concentration in the culture medium were obtained. The mathematical model of microalgae biomass growth depending on nitrogen oxides concentration was developed. Based on the solution of the mathematical model and the obtained experimental data, the concentration of nitrogen oxides for the maximal microalgae growth was determined.
