| Abstract | ||
| This investigation has been conducted to Study Chemical Oxygen Demand (COD) in Relation to Biochemical Oxygen Demand (BOD).Three replicates samples were taken in Baghdad city from :1 - From the water upper part of Army Channel , 2 –Near Al-Talbaia Bridge on Army Channel , 3 - Anaerobic main holes effluent (Septic systems) near Vegetables Station in Gamelia City , 4 –From Dyalia river near Ristmaia , 5 - From the intersection between Tigris and Dyalia river southern Baghdad , 6 - From Tigris river Near Bab –Al –Matham Bridge , 7- From Tigris river Near Al – AL-Aiemah Bridge and 8 –Waste water from Ristmaia Station before treatment . Mean values of COD and BOD in the investigated locations show strong relation with high value of correlation coefficient (r = 0.9758 ) and describe by the equation : BOD= 6.1242 + 0.3142( COD ) + 0.0008 ( COD )² The above formula used to estimate BOD depending on COD . The COD test can be run in a couple of hours instead of five days to determine BOD . ____________________________________________ | ||
