Notes:
An instrument, the Short COD Thermal Controller, was developed to make the short COD test faster, safer and more precise through automatic control of heating and agitation. The instrument was used to analyze a glucose solution, simulated tomato wastes and corn processing wastes. Glucose solutions were found to have a coefficient of variation of 1.4% compared to the 20% reported for the BOD and the 8% for the long COD. The coefficient of variation for the tomato waste was 2.7%, and on the corn processing waste the instrument was able to give more reproducible results than the inherent variability found in preparing the replicate waste samples. The new instrument reduced both the time required to analyze a large number of samples and the hazards to technicians.
