Question

A dairy is mainly involved in the operations of bottling of milk, making ice-cream and limited production of cheese. Calculate the BOD produced per 1000kg of milk processed and its population equivalent from the following data;

Quantity of milk processed daily=150000kg Waste water produced daily =240m3 BOO of waste water =1400mg/I Population equivalent per capita per day of 5-days BOD at 20C°=75g

Answer 1

BOD produced per 1000kg of milk processed = (1400mg/I x 240m3) / 150000kg = 0.192mg/I

Population equivalent = (0.192mg/I x 75g) / 5 = 0.576g
