Abstract
This paper introduces a novel method for controlling of the cyanobacteria concentration in open water reservoirs during periods of global warming. The technology is based on usage of nanophotocatalysts made from nanocarbon-metal composition with titanium as the metal. Under the natural ultraviolet radiation, the nanophotocatalysts form OH-radicals in water that destroy cyanobacteria. Field tests in natural water revealed it to be efficient with low consumption of nanocompositions (about 10 g/ha or 50 l of aqueous solution of the nanocomposition with the concentration of 200 mg/l), OH-radicals formed only in the upper water layers where cyanobacteria grow, and nanocompositions coagulate and precipitate harmless water-insoluble particles within the first day.
