A floating boom is turned on the water surface to form a continuous barrier for biofouling and impurities rising to the surface, which are then collected in form of dirty foam. A mobile system equipped with acoustic radiators is used to forcefully move the aggregation of fish - natural predators for biofouling, from a remote part of a water body to a region adjacent to a supply channel by continuously emitting energy, information, high-gradient and bioresonance signals. Simultaneously, a second acoustic module and a second acoustic-bubble module are used to form an acoustic barrier for fish - natural predators of biofouling, as well as an acoustic-bubble shield in the narrowest part of the water body. Recycled water being cooled in the water body is further purified from biofouling and impurities and fish are not released from this part of the water body. Simultaneously, a third acoustic module and a third acoustic-bubble module are used to form an acoustic barrier for juvenile fish- natural predators of biofouling, as well as an acoustic-bubble shield at the input of the supply channel of the facility of the power system. As a result, recycled water cooled in the water body is further purified from biofouling and impurities. Simultaneously, intense ultrasonic waves and low-frequency electromagnetic waves act on the biofouling at the input of a water-intake window, with simultaneous removal of biofouling from the mechanical protective screen, and at the output of the inlet pipe of the underwater structure. Simultaneously, an acoustic filter mounted at the input of the equipment of the facility of the power system performs fine purification of water from biofouling, as well as biological and mechanical impurities.
