The technological process of processing blue-green algae of freshwater reservoirs into biogas has been improved. To increase the productivity of the biogas fermentation process, a new design of vibration-resonant cavitator was created. Productivity of the developed cavitator reaches 0,75–1,0 m3/h. with a cross section of the working chamber of 10 inches. The use of the cavitation treatment of algae suspension at the stage of preparation of the algae suspension allows to increase the fermentation of biogas from biomass by 25 ÷ 30 %. The aim of the work is to improve the technological process of fermentation of biogas from blue-green algae, as well as to develop a suitable design of the vibrocavitator. The main objectives of the study are to develop the design of vibrocavitators with electromagnetic drive and study the effectiveness of their use for homogenization of blue-green algae in the process of their processing into biogas.
The results of the study allow to increase the productivity of the technology of algae processing into biogas, as well as to improve the ecological condition of water bodies and the environment by removing harmful blue-green algae from the water.
