Abstract
A system, comprising: a chlorine source in form of an electrolysis unit to generate an insitu generated active chlorine; wherein a concentration of perchlorate is not more than half of a concentration of chlorate; and pH of a fluid containing in-situ generated active chlorine is more than 7.4; a buffer tank to store a concentrate of in-situ generated active chlorine as a free available chlorine (FAC); a fluid distribution system to supply FAC in form of an in-use fluid to the cabinet; wherein the system is configured to clean and disinfect an article with the fluid while complying with national and international standards for food safety, operator's safety and regulatory requirements regarding the use of biocides.
Claims16
A method comprising:
- a) feeding a chloride source into an electrolysis unit;
- b) operating the electrolysis unit to generate a solution having an in-situ active chlorine;
- c) allowing the solution to age in a tank for a time-period of about 5 hours to 120 hours after the solution has left the electrolysis unit, to form an aged-solution having the in-situ active chlorine comprising free available chlorine (FAC);
- wherein the aged-solution has:
- (i) a concentration of perchlorate not more than half of a concentration of chlorate;
- (ii) pH of about 7.5 to about 10;
- (iii) more than 50 Mol % of the FAC as hypochlorite ion;
- and
- (iv) a concentration range of the FAC calculated as the chlorine is more than 1 g/L to about 12 g/L in the aged-solution.
