CLARIFYING, FILTERING AND DISINFECTING PROCESSING WATER FOR REUSE
First Claim
1. A method of treating and reusing wastewater for food processing, the method comprising:
- (a) conducting a coarse particle separation on the wastewater to create first stage water;
(b) separating large and small particles in the first stage water in a liquid waste separator to create a second stage water;
(c) directing the second stage water to a flocculation settling tank to aggregate remaining solids, and removing the remaining solids to create a third stage water; and
(d) treating the third stage water with at least one of UV light and chemical antimicrobials to create reusable water.

Abstract
Wastewater may be reconditioned for re-use in a food processing line. The wastewater is subjected to coarse particle separation on the wastewater to create first stage water, after which large and small particles in the first stage water are separated in a liquid waste separator to create a second stage water. The second stage water is directed to a flocculation settling tank to aggregate remaining solids, and the remaining solids are removed to create a third stage water. Finally, the third stage water is treated with at least one of UV light and chemical antimicrobials to create reusable water. The reusable water is delivered upstream to reduce fresh water requirements. Ferrate (IV) is an exemplary antimicrobial that has broad applications in the food processing line.

11. A method of processing poultry and of treating and reusing wastewater from poultry processing, the method comprising:
-
(a) immersing the poultry in a scald tank; (b) removing feathers of the poultry in a picker; (c) cleaning and processing the poultry; (d) immersing the poultry in a chill tank; and (e) further processing the poultry for packaging, wherein wastewater from at least one of steps (a), (c), (d) and (e) is treated by; (i) conducting a coarse particle separation on the wastewater to create first stage water, (ii) separating large and small particles in the first stage water in a liquid waste separator to create a second stage water, (iii) directing the second stage water to a flocculation settling tank to aggregate remaining solids, and removing the remaining solids to create a third stage water, and (iv) treating the third stage water with at least one of UV light and chemical antimicrobials to create reusable water, and wherein the reusable water is recirculated for use in at least one of steps (a), (c), (d) and (e). - View Dependent Claims (15, 16)
