Abstract
Methods and systems for treating cooling water of a retort are described. The methods and systems generate an aqueous ozone solution and combine the aqueous ozone solution with the cooling water. The methods and systems provide a safe, economical, easy to handle, and environmentally friendly solution for maintaining a retort cooling water system. The systems and methods herein remove contaminates from the cooling water, supply a continuous sanitizer created on-site, reduce the need for additional chemicals, and reduce the labor costs attributed to maintaining the retort cooling water system.

9. A method of maintaining a cooling a retort system, comprising:
-
forming an aqueous ozone solution; directing the aqueous ozone solution to a cold water holding tank, the cold water holding tank containing an amount of cold water; mixing the cold water with the aqueous ozone solution to form ozonated cold water; directing the ozonated cold water to a retort system; cooling cans with the ozonated cold water in the retort system, whereby the ozonated cold water is heated; directing the heated ozonated water to a hot water holding tank; directing the heated ozonated water from the hot water holding tank to a cooling tower for cooling; cooling the heated ozonated water; directing the cooled ozonated water to the cold water holding tank; and
,draining a portion of the cooled ozonated water from the cold water holding tank.
