Calculation of waste water discharge in an animal slaughter house http://www.waterandwastewater.com/cgi-bin/yabb/YaBB.pl?num=1142244578
Water usage at plants such as this tend to be affected by the attitudes of both the in-house operators and the local veterinary inspectors to water usage and conervation. My experience of typical "normal" unit loads, (european experience), that can be achieved at a well run slaugher facility are set out below:
Cattle: 0.9 m3 /head and 3.5 kg BOD /head. (This includes an allowance for washing of livestock pens, and delivery vehicles, running / recovery of casings and edible fat, normal slaughtering aspects, very good blood collection, but excludes any allowances for cooking of cuts, pressing of paunch or belly grass materials, or for other value added processing).
Pigs: 0.5 m3/head, and 0.6 kg BOD per head. (This also includes an allowance for washing of livestock pens, and delivery vehicles, running / recovery of casings, normal slaughtering aspects, very good blood collection, but excludes any allowances for cooking, curing, or other valued processing).
Sheep: 0.08m3/head and 0.35 kg BOD per head processed.
(This too includes an allowance for washing of livestock pens, and delivery vehicles, running / recovery of casings, normal slaughtering aspects, very good blood collection, but excludes any allowances for cooking or other value added processing).
