Synelnikov O. Ensuring ecological safety of reservoirsby using microalgae for production energy

The dissertation is devoted to the increase of ecological safety of Dnipro cascade reservoirs under uncontrolled outbreak of cyanobacteria by creation of scientific and technological organization of collection of algae and their usage as raw material for the production of energy. A scientific feasibility of obtaining biogas from cyanobacteria biomass cyanobacteria (chemical, microbiological and biochemical patterns of the process) was grounded. The analysis of the optimal conditions for the implementation of bio methane genesisin the system, which includes an organic substrate of blue-green algae, was conducted. The influence of various factors on the viability of differenttypes of bacteria and the progress of the biogas synthesis of blue-green algae was studied. Effectiveness of pre-treatment of blue-green algaebiomass in the field of hydrodynamic cavitation to increase completeness of decomposition of biomass was discovered. Flowchart of strategy to avoid environmental hazards from uncontrolled development of cyanobacteria and their impact on the environment was created.
