Abstract

The regulation for the waste water from a boiled noodle plant is generally restricted by BOD whose measuring is complicated and takes so long time. A method calculating BOD from CODcr was investigated to obtain the following results.
BOD value of the waste water from boiled noodle was highly correlative with CODcr value and the equation obtained by a least squares method is as follows:
BOD=0.630×CODcr+43
correlation coefficient: 0.99
significant at the 1% level of confidence
