A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.

An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

A method for filling a container (2) with a filling product, comprising the steps of: positioning the container (2) in a filling station (1) so that its mouth (2b) is below the filling valve (9); separating a treatment volume (40) of the neck (2a) comprised between the filling valve (9) and at least one part of the neck (2a) of the container (2) from an external environment (6) containing the body (2d) of the container (2); dispensing plasma into the treatment volume (40) so that it flows over the neck (2a) of the container (2); enabling the filling valve (9) to dispense the filling product into the container (2).

A plasma generating method, used in a plasma generating apparatus which includes a container, a first electrode, and a second electrode, includes: supplying a liquid in the container so that the second electrode is in contact with the liquid; in a first period, generating first plasma in a bubble generated in the liquid by applying a first voltage between the first electrode and the second electrode; supplying a first gas in the liquid in a second period after the first period; and generating second plasma in the first gas by applying a second voltage between the first electrode and the second electrode. In generating the first plasma, the first gas is not supplied in the liquid. The bubble contains a second gas.
