World industrial reception of micro seaweed Chlorella biomass increases every year and is estimated in thousand tons. The high production efficiency (end-product accumulation) and a unique set of natural useful components have defined wide application of chlorella in various spheres activity of the person for a long time. Chlorella is applied in agriculture, medicine (pharmacy), in the food-processing industry, perfumery, sewage treatment etc.
Micro seaweed Chlorella is grown and in open cultivators (systems) as well as in closed cultivators. The technology of a micro seaweed biomass production differs with observance of special parameters (cleanliness, high quality of initial components). Now a day there is enough wide spectrums of photoreactors. It is technological equipment for industrial production of micro seaweed. Photoreactors are closed systems of transparent capacities (pipes) in which the nutrient medium with culture of micro seaweed is circulated. Passing the whole way a like a coil, suspension reaches in special memory tank where the next portion of СО2 is received which is during the further movement intervals equally distributed on all biomass. In nutrient medium nitrogen, phosphorus, potassium, micro elements take part. In industrial production the light which is necessary for photosynthesis is provided with natural solar illumination. When the mass of weight Chlorella reaches a certain concentration, half of the volume with finished goods is merged (it occurs for time a day), the system is filled up with a fresh nutrient medium, and the cycle is repeated. The important detail is cleaning of the systems. As well as in the pool, micro seaweed can be besieged on the walls of pipes. In these cases special systems of cleaning (cleaning pistons) are applied. There is a simple and an effective decision: at the required moment a foam rubber ball the diameter of which is equal to the section of pipes is launched into the system. Moving ahead under the pressure like a coil, it clears everything that has been stuck to the walls, and after a while the system is again clean and transparent. The main advantage of closed glass piped reactors is the possibility of regulating the terms conditions of production of a micro seaweed biomass. It allows growing clean cultures that are to produce standard production. But the productivity of glass tubed photoreactors in certain cases is to 10 times above, than in pools.
