YORDANOV, D., 2010. Preliminary study of the efficiency of ultrafiltration treatment of poultry slaughterhouse wastewater. Bulg. J. Agric. Sci., 16: 700-704

Poultry slaughterhouses use relatively high amount of water with an average consumption of 26.5 L/bird during primary and secondary processing of live birds to meat. The used water contains proteins, fats, carbohydrates from meat, blood, skin and feather, resulting in much higher biological oxygen demand (BOD) and chemical oxygen demand (COD). A lot of attention has been focused on the development of unconventional methods for wastewater treatment. The possibility of using the ultrafiltration for poultry wastewater treatment was investigated. The results showed that the ultrafiltration could be an efficient purification method. Its application resulted in about 99 % and 98 % removal of fats and suspended substances. The efficiency of COD and BOD5 removal exceeded 94 %.

Key words: poultry slaughterhouse wastewater, ultrafiltration, BOD5, COD, total suspended solids, fat
