Abstract |
Data on processes that contribute to wastewater pollution were obtained from five of the six poultry processing plants in Delaware. BOD, COD, and suspended solids tests were run on samples of wastewater from various locations within the plants. A regression analysis of COD and BOD in poultry processing wastewater indicated a fairly good approximation of BOD values can be estimated from COD values. For the various plants, BOD values averaged between .9 and 2.3 lbs/1,000 birds for the scalding operation, between .2 and 7.8 lbs./1,000 birds for the dressing operation, .4 to 13.4 lbs./1,000 birds for the eviscerating operation, and .4 to 4.6 lbs./1,000 birds for the chilling operation. It appears that most poultry processing plants could reduce the volume and strength of their wastewater. (Author) |
