The exact determination of the interfacial area in gas/liquid systems is essential for optimized process performance and control. This experimental study contains investigations of an air/water system using three measurement techniques with regard to determining the change in bubble size as a function of stirrer speed. The precise, self-referential method of photo-optical analysis is considered in greater detail regarding image processing. It is shown that the latest developments in the field of optics and photo imaging have provided valuable inputs to establish an accurate real-time size measurement technique. This is necessary, as laser-based methods only provide insufficient process data.
