Abstract

BOD parameter is a key factor in standardizing treatment plants and sanitation facilities in the interest of public health. Its dynamics is examined in this study using abattoir effluent stored under laboratory condition over a period of 14 days. The dissolved oxygen surrogate for BOD5 determination varied as a function of biodegradable organics, and plausibly influenced by daily variation in temperature. Optimum oxygen depletion was recorded on day 7 but maximum BOD5 value was recorded on day 10. Instantaneous rate for BOD5 change peaked at 2.91 mg/l/day on day 3 and hit a minimum low at 0.22mg/l/day on day 14. Average rate of change in BOD5 was 1×10-3 mg/l/day. These data are crucial in the development of treatment/sanitation facility in the management of abattoir facilities.
