    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.

    Quality level of surface water at the control points of the western bug river (Lviv region)
    (Видавництво Львівської політехніки, 2020-02-24) Odnorih, Zoryana; Manko, Roman; Malovanyy, Myroslav; Soloviy, Christina; Lviv Polytechnic National University; Department of water cadaster and water monitoring Water basin management of the Western Bug and San rivers
    The article analyzes the negative impact of enterprises and public utilities on the surface water quality of the Western Bug River basin (within the Lviv region). The dynamics of changes of indicators of the main pollutants at six control points (2016–2018) and the assessment of surface water quality for 2018 are presented. It is proposed to replace the control units on the Western Bug River and its tributaries in order to obtain more accurate information and improve the work on the basin water management.
