| Abstract: | Presented in this paper is a simple, speedy and reliable method for. determining BOD5 in. water samples. After the values of CODCr have been determined, three proper diluted mulples are calculated in accordance with the general formula for evaluating the coefficients of dilution:Cn = CODCr/6.5 ×2n-1(n= 1,2,3) |
