Abstract:

All poultry processing plants generate raw wastewater with relatively high phosphorus levels. Phosphorus reaches the wastewater stream as a result of:

Release from the meat being processed


Use of trisodium phosphate for bird washing


Use of phosphorus containing marinates


Use of phosphate based sanitation chemicals


The techniques used for the removal of phosphorus from poultry processing wastewater cover the full range of typical techniques used throughout the wastewater industry. These include:

Source reduction through the use of alternative chemicals and marinates


Chemical coagulation during pretreatment


Biological nutrient removal during biological treatment


Chemical coagulation during final clarification and polishing


Currently, few plants have permits with phosphorus limitations. There is no particular technique that dominates the facilities that are required to remove phosphorus. This is due to the fact that each facility has to be evaluated based on the specific situation that exists as relates to:

Existing facility capabilities


Treatment requirements


Sludge handling capabilities


Other site specific considerations
