    The analysis of perspective collection and concentration technologies of excess biomass in the technologies of wastewater and surface water biological treatment with the use of aquatic organisms has been carried out. The scheme of a life cycle of the aquatic organisms in wastewater and surface water treatment technologies has been proposed. The analysis of technological approaches for biomass collection of three types: aquatic plants and macroalgae; aquatic plants with a developed root system and microalgae of aquatic organisms has been carried out. A strategy for concentrating microalgae has been proposed. The high efficiency of the coagulation-flocculation gravitational thickening method of freshwater microalgae suspensions of the Microcystis aeruginosa species has been confirmed in laboratory conditions.

    Handling the pharmaceutical industry waste in Ukraine and the UA
    (Видавництво Львівської політехніки, 2020-02-10) Popovych, Olena; Vronska, Nataliya; Yatchyshyn, Yuriy; Zaharko, Yaroslava; Lviv Polytechnic National University
    The prospects of the pharmaceutical industry development are closely connected with scientific and technological progress. In Ukraine, handling hazardous medical waste is an open question. The rapid development of pharmacy in recent years has created and increased the possibility of the generation and accumulation of pharmaceutical waste at the enterprises and in the environment. Only a few enterprises deal with medical waste disposal. Medical waste recycling requires an extremely high level of attention and carries great risks associated with handling this medical waste. When medical waste is burnt, strong pollutants are released into the atmosphere – carcinogens, furans and dioxins from chlorine halogen compounds, namely dumping of the hazardous material that contains heavy metals, and is likely to cause bioaccumulative hazardous substances to transfer to the environment.
