Abstract
The current review aims at improving the understanding on the treatment frameworks related to poultry slaughterhouse wastewater (PSWW) treatment efficiency. Technologies used for nutrient and organic removal during the last 10 years are discussed in this article. The selection of specific treatment is dependent on the characteristics of wastewater, existing treatment cost, and compliance with regulations. The reverse osmosis (RO) technology, dissolved air flotation (DAF), and integrated fixed film activated sludge (IFAS) are among the technologies that can produce high-quality treated effluents. DAF is known to have the ability to remove 98.6% of biochemical oxygen demand (BOD) and 97.9% of chemical oxygen demand (COD) while RO can only remove up to 90.0% and 97.9% of total nitrogen (TN) and COD. The anaerobic sequencing batch reactor (ANSBR) technology efficiently gave 90% of TN and COD removal. However, gaps and limitations have been recognized in regards to TP removal. Advanced technologies are considered successful in terms of water recycling and reuse and waste reduction in poultry slaughterhouses that can offer a more cost-effective waste management.
