    Efficiency of application of the microbiological method of waste water treatment to remove hexamethylendiamine
    (Видавництво Львівської політехніки, 2021-03-03) Lytvynenko, Valeriia; Dychko, Alina; National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”
    Wastewater contaminated with hexamethylenediamine (HMD), which is discharged into natural reservoirs, causes damage and loss of hydrobionts, worsens the quality of water which becomes unsuitable for use. For wastewater treatment from HMD, the possibility of applying bacterial cultures- destructors which use the HMD as a nutrition source is considered.

    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.
