Abstract

An experiment was conducted in an aeration system made from 2000 mL Erlenmeyer Flask to investigate the effect of sodium sulfite with cobalt chloride and the sparging nitrogen gas on the measurement of the oxygen transfer coefficient. Twice the theoretical quantity of sodium sulfite that is required to react with dissolved oxygen, or nitrogen sparging at a rate equivalent to that of air used during the aeration process, was used to deoxygenate the water. The results obtained from the study were consistent and repeatable and showed no significant differences in the values of the oxygen transfer coefficient obtained by the two methods.
