Industrial waste water reclamation process

An improved water reclamation process for removing emulsified fats, oils, and greases, and particulates from an animal or food processing waste stream to produce water suitable for reuse in non-food processing industrial applications, consisting of the steps of:

• providing a storage reservoir having an inlet and an outlet;
• directing said animal or food processing, waste stream to the inlet of said storage reservoir;
• continuously monitoring the inlet of said storage reservoir for pH and turbidity of said waste stream, and continuously adjusting the pH when necessary to a desired value to aid in separation of said emulsified fats, oils, and greases from said waste stream;
• diverting the inlet waste stream away from said inlet of said storage reservoir if the turbidity exceeds a predetermined value;
• providing a first settling tank having a bottom mounted inlet and a centrally located outlet coupled in a series arrangement with said reservoir outlet;
• transferring the waste stream from said storage reservoir to an air sparging coil for injecting air into said waste stream to accelerate the separation of said emulsified fats, oils, and greases from said waste stream;
• discharging said waste stream into a first settling tank through a distribution header located in the lower portion of said first settling tank for reducing turbulence;
• providing a second settling tank having a centrally mounted inlet and a centrally located outlet;
• transferring the waste stream from said first settling tank to said second settling tank for separating said emulsified fats, oils, and greases, and particulates from said waste stream;
• skimming the separated fats, oils, and greases, and particulates from the waste stream in the second settling tank;
• providing a distribution tank having a centrally mounted inlet and a bottom located outlet;
• transferring the waste stream from said second settling tank through said centrally located outlet to said distribution tank;
• providing a plurality of pressurized polishing filters for removing particulates from the waste stream remaining after skimming;
• transferring the waste stream from said distribution tank to said polishing filters by means of a pump;
• providing ultraviolet exposure for killing bacteria in the waste stream;
• and
• directing the waste stream from the outlet of said third settling tank, through said polishing filters and said ultraviolet exposure to produce a treated waste stream suitable for use or storage in non-food processing industrial purposes.
