Systems and methods for producing aqueous solutions and gases having disinfecting properties and substantially eliminating impurities

A device for producing a vapor having disinfecting properties when exposed to ambient moisture, comprising:

• at least two outer membranes permeable to moisture and vapor;
• and
• at least one inner membrane sealed to the at least two outer membranes along at least two edges of the device,
• wherein the outer membranes and the inner membrane together form a first compartment and a second compartment separated by the inner membrane, wherein the first compartment is provided with a first dry reactant and the second compartment is provided with a second dry reactant, whereby the vapor having disinfecting properties is generated and released to the atmosphere from the device when the first dry reactant in the first compartment is hydrated by moisture penetrating the outer membranes, and the hydrated first dry reactant is transported across the inner membrane to contact the second dry reactant in the second compartment to generate the vapor having disinfecting properties.

A system for producing a disinfectant selected from the group consisting of:

• peracetic acid, chlorous acid, hydrogen peroxide, bromine, sulfur dioxide, and carbon dioxide, comprising:
• a disinfectant generating device comprising a membrane shell defining at least two compartments;
• a first reactant selected from the group consisting of:
• tetraacetylethylenediamine (TAED), sodium bromide, sodium bisulfite, sodium carbonate, and chlorite compounds;
• and
• a second reactant selected from the group consisting of:
• peroxygen compounds, sodium percarbonate, sodium perborate, urea hydrogen peroxide, potassium monopersulfate compounds, citric acid, fumaric acid, and other acid compounds.
