Abstract: A device for generating a disinfectant solution based on metal and water atoms , including at least one sealable enclosure, where at least one electrode is installed. The sealable enclosure further includes an inlet and an outlet. The device also includes an energy source that may be in contact with the fluid, or may be insulated from the fluid. Thus, the energy source may be made available inside the sealable enclosure or on the outside the sealable enclosure, or both. The device enables the rapid production of a disinfectant solution based on a mixture of fluid such as water and biocidal metal atoms such as silver atoms with increased antibacterial, virucidal and fungicidal properties.
