Patent number: 9850154Abstract: The invention provides methods and compositions for reducing the amount of water required in an industrial process, especially a bottling process such as beer or beverage manufacturing. The method comprising the steps of: collecting water used to rinse cleaned and/or dirty recycled bottles, spraying the collected water at a food contacting piece of equipment as part of a CIP rinse, and passing the CIP second rinse water into a cooling tower as make-up water. The method allows for the re-use of water already in the system but by being careful where each water stream goes the water does not accumulate contaminants that would damage the cooling tower or foul the bottled product or vessel that is cleaned by CIP method.Type: GrantFiled: December 30, 2013Date of Patent: December 26, 2017Assignee: ECOLAB USA INC.Inventors: Deepak A.
