The inventions of the present disclosure are directed to processes designed to recover water used in certain aspects of the processing of poultry, treat the recovered water to remove solids, fats, oils and greases, animal proteins and pathogenic organisms and to reuse the treated water for poultry processing operations. The processes described herein reduce bacteria and microorganisms associated with the poultry and reuse water. The present disclosure can be employed with an approach that includes unexpected positive results of reacting ozone and chlorine with water being treated for reuse to generate hypochlorous acid and/or other effective biocides. Ozone reacts with fats, oils, and greases, dissolved in the reuse water, to produce specific surface-active agents and surfactants which reduce the surface tension of the water which it is dissolved. The combination of these surface-active agents and surfactants and the biocides cause an extraordinary release and destruction of bacteria from the poultry carcass as well as the reuse water.

What is claimed is: 1. A method for recycling water used in the processing of poultry comprising the steps of: recovering a portion of water used in a non-chilling processing step of poultry processing, said step of recovering water includes passing said water through a recovery sump comprising a basin having a first compartment for receiving said recovered water and barrier in said basin forming a second compartment, said first compartment having a means for skimming solids from said recovered water leaving skimmed water that flows into said second compartment, said second compartment having means for allowing said skimmed water to exit said basin for further processing; treating said recovered water to reduce impurities and provide disinfection, said step of treating including reacting ozone with said recovered water to produce surfactants; and reusing said treated water in at least one other step of poultry processing. 2. The method according to claim 1, wherein said step of recovering water is from at least one step in said poultry processing selected from the group consisting of wash steps, non-final rinse steps, water sprays, flumes and final rinse step. 3. The method according to claim 1, wherein said step of treating water includes reacting ozone with said recovered water to produce surfactants and reduce the surface tension of said recovered water. 4. The method according to claim 1, wherein said step of treating includes removal of one or more contaminants selected from the group consisting of solid matter, floatable fats, oils, grease, lipids, blood proteins, carbohydrates, suspended and dissolved organic materials, animal parts and debris. 5. The method according to claim 1, wherein said treated water has a turbidity of less than or equal to 5 Nephelometric Turbidity Units (NTU). 6. The method of processing poultry according to claim 1, wherein said step of reusing said treated water includes introduction of said treated water into pores and membranes of poultry. 7. The method according to claim 1, wherein said recovery sump further comprises a filter for screening said recovered water prior to said recovered water being received by said first compartment, and said means for skimming solids communicates with a drain whereby the skimmed solids may be continuously removed from said recovered water. 8. The method according to claim 1, wherein said basin further comprises at least one drain outlet. 9. The method according to claim 1, wherein said basin comprises a plurality of compartments each, except said first compartment, in fluid communication with the preceding compartment, and each, except the last compartment having a means for skimming solids. 10. The method according to claim 1, wherein said step of treating further comprises the steps of: filtering said recovered water to remove non-dissolved components; and disinfecting said filtered water to limit its microbiological activity. 11. The method according to claim 1, further including a step of recovering a further portion of water used in a chilling processing step of poultry processing, whereby no more than approximately 40 percent of said recovered water originates in a chilling step. 12. A method for recycling water used in the processing of poultry comprising the steps of: recovering a portion of water used in a non-chilling processing step of poultry processing, said recovered water containing animal fats; treating said recovered water to reduce impurities and provide disinfection, said step of treating further including introducing ozone into said recovered water, wherein said introduction of said ozone saponifies said animal fats to produce a surfactant, introducing chlorine into said recovered water, and reacting said ozone and said chlorine with said recovered water to generate a biocide; and reusing said treated water in at least one other step of poultry processing. 13. A method for recycling water used in the processing of poultry comprising the steps of: recovering a portion of water used in a non-chilling processing step of poultry processing; treating said recovered water to reduce impurities and provide disinfection, said step of treating including introducing ozone and chlorine into said recovered water, said step of treating further including reacting said ozone and said chlorine with said recovered water to generate a biocide; and reusing said treated water in at least one other step of poultry processing. 14. The method of processing poultry according to claim 13, wherein said step of treating includes generating a chloramine via said reaction of said ozone and said chlorine with said recovered water. 15. The method of processing poultry according to claim 13, wherein said step of treating includes destroying bacteria and microorganisms from said recovered water. 16. The method of processing poultry according to claim 13, wherein said step of treating includes releasing and destroying bacteria and microorganisms from said poultry. 17. The method according to claim 13, wherein said treated water has a turbidity of less than or equal to 5 Nephelometric Turbidity Units (NTU). 18. The method according to claim 13, wherein said step of recovering water includes passing said water through a recovery sump comprising a basin having a first compartment for receiving said recovered water and barrier in said basin forming a second compartment, said first compartment having at least one weir pipe for skimming solids from the surface of said recovered water leaving skimmed water which, when said skimmed water reaches a level higher than said barrier, flows into said second compartment, and wherein said second compartment has an exit orifice in fluid communication therewith for allowing said skimmed water to exit said basin for further processing. 19. The method according to claim 18, wherein said recovery sump further comprises a filter for screening said recovered water prior to said recovered water being received by said first compartment, and said weir pipe communicates with a drain whereby the skimmed solids may be continuously removed from said recovered water. 20. A method of processing poultry comprising the steps of: recovering water used in at least one processing step associated with processing poultry; treating said recovered water to reduce microorganisms within said poultry, said step of treating including introducing ozone and chlorine into said recovered water, reacting ozone with said recovered water to produce surfactants such that the surface tension of said recovered water about said poultry is reduced, said step of treating further including reacting said ozone and said chlorine with said recovered water to generate a biocide such that bacteria and microorganisms are released from said poultry and destroyed; and reintroducing said treated water into any of said at least one processing step whereby said treated water is introduced into said poultry and said introduction reduces the level of microorganisms within said poultry.
