Specifically, COD values for raw sewage correlated well with the 5-day BOD; and raw sewage-stillage mixtures with COD values above 500 ppm were best correlated with 20-day BOD. All effluent samples from either straight domestic sewage or sewage-stillage mixtures had a COD-BOD relationship similar to that found for raw sewage. Equations are presented for estimating BOD values from the modified COD method employed in this work. %U https://www.ajevonline.org/content/ajev/10/4/199.full.pdf
