Protein from carcass debris and blood
is one of the major
pollutants in the poultry processing
wastewater (PPW) and requires intensive
treatment before being discharged.
Attempts to utilize the protein as
fertilizer or animal feed were unsuccessful
due to their low profitability.
However, the value of protein could
be leveraged if it could be used as
fermentation nitrogen source.
Ultrafiltration (UF), a membrane-based
process, has been successfully employed
for protein purification in dairy
industry. We hypothesize that
UF may be an effective means to recover
protein from PPW.
