Abstract

The study conducted here was done to test the validity of a study conducted twenty years ago, which found that the ratio between COD and BODs was 1.6 for different pulp and paper mill wastewater effluents. This study was conducted by first treating three different pulping operation wastewaters. BOD and COD tests were then conducted on the treated wastewater samples. The results from these BOD and COD tests were found to be invalid due to problems encounter during the experiment. Due to the results being invalid, ii was impossible to compare results found by this study and those found by the past study. Although the study was found to be invalid, many important lessons can be learned from conducting an experiment like this one.
