PLANT FOR CONTINUOUS GROWING PLANKTONIC ALGAE Russian patent published in 2015 - IPC C12M1/00 C12M3/02 A01G33/00 C12N1/12 

FIELD: biotechnology.

SUBSTANCE: device comprises two aquariums for the suspension, located on the frame, light fixtures, tanks for preparing the nutrient solution and for collection and storage of finished suspension, connected to the aquariums by pipelines. Two aquariums for the suspension of microalgae are mounted on the frame with the ability of changing the distance between them and are connected to each other in the lower part of the vertical walls by the pipeline to counterbalance the volume of the suspension in both aquariums. Each aquarium for the suspension has two discharge openings, one of which is made in the lower part of the side wall for discharging the finished suspension of chlorella and its removal through the pipeline to the tank for collecting and storing the suspension, and the second hole is formed in the lower plane. One of the aquariums for the suspension is made with the ability of growing the stock culture and ensuring the uniform biotechnological process. The light fixtures in each aquarium are arranged eccentrically with respect to its longitudinal axis. The light fixture located between the aquariums is mounted on a separate frame regardless of the frame and the aquariums with the possibility of free displacement and removal in transfer to sunlight. The tank for the nutrient solution is placed on a level above the aquariums, and has two holes made in the vertical side wall, the first of which is located at the level of 0.5 volume, and the second - in the bottom layer with the possibility of attachment to them of the pipelines to discharge the nutrient solution to the aquariums.

EFFECT: increased productivity of cultivation of chlorella, ease of use, and safety of operation.
