The bioreactor with use of impeller mixers for cultivation of biomass of microalgas

Бесплатный доступ

Cultivation of microalgas gains popularity in the different countries in recent years. As a result of such intensive development of production the extensive experience in constructioning of various types of bioreactors was gained. The bioreactor for cultivation of microalgas having the cylindrical housing divided by horizontal partitions into sections for input and output of cultural liquid and additional section with an internal specular surface, the bubble device and gate stirrers fixed on blades, the rigidly bound to shaft is developed. Planetary rotation of gate stirrers concerning a shaft creates additional turbulization of the environment, provides alignment of concentration of cells of biomass, prevents emergence of hold-up spots, a premature deposition of cages of culture on the bottom of the device and increases efficiency of cultivation of microalgas. In the main section suspension of a microalga is exposed to the uniform light energy by means of coaxially established filament lamp of a daylight and to reflection of light from an internal specular surface of a housing...
