FIELD: biotechnology.
SUBSTANCE: invention relates to systems and devices for contactless removal of hydrobionts and suspensions from the stream of water withdrawn from natural water sources. Water is taken from any horizons of the water source. System is placed on the water horizon by means of a float and includes a water intake with an inlet for a stream containing filtration objects – a water-fish mixture. System contains waterproof discs forming a flotation cell, the internal volume of which is divided into parts by a partition, connected to the air-lift section of the mine to increase the concentration of water-fish-air mixture. Flotation cell has an outlet for a stream containing filtering objects of increased concentration, and an outlet for a stream cleared of filtration objects.
EFFECT: exclusion of the death of hydrobionts is ensured at entering water consumer technological devices.
