Claim Text:
1. A method for reducing population of a microbe on an object, comprising: delivering a liquid composition of carboxylic acid and delivering a liquid composition of an oxidizing agent to a site at which a peroxycarboxylic acid composition will be made and used wherein the liquid compositions are substantially free of a chelating agent; pretreating the liquid compositions with at least one pretreatment column to remove metal before mixing the liquid composition of carboxylic acid and the liquid composition of an oxidizing agent to form a mixed composition, wherein the pretreatment column is substantially free of chelating agent; reacting the pretreated liquid compositions in the presence of a reaction catalyst that can be physically removed from reaction mixture to produce the peroxycarboxylic acid composition; recovering the peroxycarboxylic acid composition, wherein the peroxycarboxylic acid composition is substantially free of chelating agent; and applying the peroxycarboxylic acid composition to an object to reduce the population of microbe on the object.
