    Qualitative and quantitative characteristics of biogas of cyanea organic mass
    (Publishing House of Lviv Polytechnic National University, 2016) Digtiar, Sergy
    The article discusses the results of studies of the methane production from cyan biomass based on the data obtained in the course of a laboratory experiments. The yield of biogas was calculated from the substrate per unit volume, and its energy properties were determined. Experimental data indicates the feasibility and economic viability of this biotechnology.

    Reduction of the environmental threat from uncontrolled development of cyanobacteria in the waters of the Dnieper reservoirs
    (Publishing House of Lviv Polytechnic National University, 2016) Malovanyy, Myroslav; Nykyforov, Volodymyr; Kharlamova, Olena; Synelnikov, Alexander; Dereyko, Khrystyna
    We have analyzed the ecological hazard that has emerged as a result of the construction of hydropower plants on the Dnieper, which became the cause of uncontrolled development of cyanobacteria. The environmental risks that are caused by the uncontrolled development of cyanobacteria and their biodegradability were studied. The efficiency of application of the known methods of suppression of mass development of the blue-green algae was analyzed. The amount of biogas that can be synthesized from cyanobacteria biomass of Kremenchug reservoir was estimated. The strategy of avoiding the ecological disaster from the uncontrolled development of cyanobacteria and its negative impact on the environment was suggested.
