Regulatory environmental permits governing wastewater disposal have become stricter for poultry processing plants that discharge effluent directly into the environment or pre-treat their wastewater stream prior to discharge to a municipal sewer systems. Therefore, more effective means of on-site wastewater treatment is a constant demand. The viability of membrane filtration as an on-site treatment method for pre- and post-DAF (dissolved air flotation) poultry processing wastewater (PPW) was investigated. A performance index (Pmi) was used to indicate which membrane was the most effective and suitable for the membrane filtration of pre-and post-DAF PPW. For the membranes tested, the 0.3m PVDF membrane was determined to be the most effective in treating pre-DAF PPW by producing a 115 Lm-2h-1 permeate flux, while the 100,000 MWCO Ultrafilic membrane was determined to be the most effective in treating post-DAF PPW by producing a 224 Lm-2h-1 permeate flux. COD, TS and TSS reductions are evaluated and reported.
