In the modern world, water filtration is performed to improve its quality. The most commonly used minerals are zeolite and shungite, as well as filters with nano-sized pores. Due to processes in boundary environments, the resulting waters before and after filtration possess specific properties. Studies after filtration show the structuring of clusters of water molecules. The most stable clusters comprise of two, four, and six water molecules. Hexagonal structures with six water molecules form the basis for the symmetry in the formation of snowflakes. Oleg Mosin at Moscow State University of Applied Biotechnology conducted research on the modeling of water clusters before and after filtration. Since 2020, the author's team has been studying structuring water clusters using patented Swiss systems called EVOdrop. A program for training students by Mario Iliev is being developed. The students participate in experiments involving the research of Non-equilibrium energy spectrum (NES), Differential non-equilibrium energy spectrum (DNES), pH, oxidation-reduction potential (ORP), and Nuclear Magnetic Resonance (NMR). The knowledge acquired after training is applicable in medical biophysics and nanotechnologies. The effects of water restructuring and changes in its physicochemical parameters are analyzed in applied medicine.
