1. A system, comprising:
(a) a reservoir of a chlorine source,
(b) an electrolysis unit,
(c) a storage tank, and
(d) a fluid distribution system,
wherein the chlorine source is configured to be fed into the electrolysis unit to generate a solution having an in-situ active chlorine comprising free available chlorine (FAC),
wherein the storage tank is configured to store the solution,
wherein the fluid distribution system is configured to distribute the solution to a point of use;
wherein the solution at the point of use has:
(i) a concentration of perchlorate not more than half of a concentration of chlorate;
(ii) pH about 7.5 to about 8.5;
(iii) more than 50 Mol % of the FAC as hypochlorite ion;
(iv) a concentration range of the FAC more than 1 g/L to about 10 g/L; and
(v) less than 1 Mol % of the FAC as hypochlorous acid;
wherein the system is configured to: a) reduce a microbial contaminant from an article exposed to the solution at the point of use for a particular time having temperature between about 30° C. to about 60° C., such that the microbial contaminant remaining after treatment is less than that of the microbial contaminant remaining on the article after being exposed to a hot water basin system for the same particular time and having temperature of a fluid in the hot water basin system between about 80° C. to about 100° C.; and b) avoid cross contamination between items cut using the article sterilized by the solution at the point of use.
