WEF Discussion Forums : Biological Nutrient Removal : simple calibration method for COD and BOD In a fiber recycling plant, the ETP is being established. Since the plant is small and effluent is just 3000 lt per hour, they have set up a small lab. But don't have any equipment for BOD, COD measurement. Can any body help me out for BOD and COD calibration.
