Evaluation Method of Emulsion Using Chemical Oxygen Demand

The “gas–liquid two-phases mixed flow” mechanism that fine bubble generation uses rapidly swirling water, which shear gas and making small bubbles in water. Based on this mechanism, sending liquid such as oil into the water instead of it able to be emulsified. At present, evaluation methods for emulsions are using particle size distribution dispersion stability. However, emulsion with bad separation behavior has a problem catch only some dispersed particles use them whole evaluation. In study we examined evaluated by chemical oxygen demand (COD) express numerical including cannot dispersed. Using three one oil, an anionic nonionic emulsifier were added another kind oil. It was confirmed COD decreased type most evaporate. These results lead conclusion performance could expressed numerically, not We also directly analyzed evaporate components compared results.
