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.

1. A method of recycling water for use in an industrial process comprising the steps of: collecting a fluid used to rinse bottles, wherein the fluid comprises aluminum, residual solids, a colloid, dissolved matter, and a surfactant;reducing a temperature of the fluid to ambient temperature,adding an adsorbent to adsorb the surfactant in the fluid,precipitating the aluminum by reducing the pH to 6.5 to 7.5, wherein the reducing the pH is performed after adding the adsorbent,clarifying the fluid to remove precipitated solids,removing residual solids from the fluid by a method selected from the group consisting of: multi-media filter, microfiltration, centrifugation, and any combination thereof,removing the colloid from the fluid by ultrafiltration, andremoving dissolved matter from the fluid by a method selected from the group consisting of nanofiltration, reverse osmosis, and any combination thereof. 2. The method of claim 1, further comprising passing the fluid to an industrial process fluid stream selected from the group consisting of: clean in place, pasteurizing, cooling tower, boiler, crate washing, belt lube, vacuum pump sealing, floor washing, and any combination thereof, wherein passing the fluid to the industrial process is performed after completing the steps of claim 1. 3. The method of claim 1, further comprising adding fresh water to the fluid to be used in the industrial process, wherein the fresh water is added in an amount insufficient for the industrial process to be successfully completed but for the presence of the fluid. 4. The method of claim 1, wherein the aluminum is precipitated by reducing the pH to 6.5. 5. The method of claim 1, wherein the adsorbent is a natural or chemically modified clay, activated carbon, a polymeric adsorbent, modified silica, an inorganic-organic composite nanoparticle, or combination thereof.
