Upstream hydrogen peroxide nebulizing sanitation system

A method of treating a flow of an airstream, the method comprising:

• collecting an airstream at an inlet of a plenum having the inlet and an outlet;
• providing an chemical intervention solution in the form of a aerosol to the airstream at least partially in the plenum;
• routing the airstream to a desiccant subsystem;
• applying ultraviolet (UV) radiation to the desiccant, wherein the UV radiation has a sufficiently low wavelength to cause water from the airstream captured by the desiccant or the aerosol captured by the desiccant to react with a catalyst to form one or more reactive oxygen species;
• and
• emitting the airstream, including the generated one or more reactive oxygen species, at the outlet.

A method of treating a food product, the method comprising:

• providing an air sanitation system in a facility containing food products, the air sanitation system comprising:
• a housing defining a plenum having an inlet and an outlet;
• an ultraviolet (UV) light source arranged within the plenum and configured to provide UV light to an area of the plenum between the inlet and the outlet;
• a nebulizer arranged between the inlet and the UV light source;
• and
• a hydrated quad-metallic compound comprising a desiccant material and a catalyzing agent, disposed in the area;
• collecting an airstream at the inlet;
• providing a nebulized agent in the form of an aerosol, mist, vapor or fog to the airstream by the nebulizer;
• routing the airstream to the hydrated quad-metallic compound;
• applying the UV light to the hydrated quad-metallic compound to generate one or more reactive oxygen species from water captured by the desiccant or the chemical intervention solution;
• and
• emitting the airstream, including the generated one or more reactive oxygen species, at the outlet.
