Abstract

In recent times, massive cultivation of microalgae has been widespread for use in the national economy. In this plan, chlorella and spirulina are of greatest interest. Chlorella is a single-celled green algae, globular or elliptical in the size of 0.005-0.010 mm. The nutrient solution in which the seaweed develops has the form of a green slurry of cells that are invisible to the simple eye. Spirulina is a blue-green algae with a cell size of 15x60 nm, in which there is no solid shell. In nature, microalgae are very common, but their productivity is low. When creating optimal conditions for growing, they must produce high yields. Experiments have established that the main parameters that determine the intensity of growing algae are: the temperature of the suspension, the mode of irradiation, composition and concentration of the nutrient medium, the concentration of CO2 in the air bubbles. The estimation of the energy efficiency of the process of cultivation of microalgae on sewage, the study of temperature and irradiation regimes and their optimization was carried out in a cultivator of the deep type, the characteristic feature of which is the use of immersed mobile sources of optical radiation. For the purpose of studying the system of thermostabilization, the specific power of the system necessary to maintain a given slurry temperature was determined; the effect of the daily flow of suspension on the capacity of the flow water heater; the dependence of the duration of heating of the suspension of microalgae on the power of the heating elements of the flow water heater.
