In order to have a uniform bubble size, effect of liquid velocity was utilized in a better manner with a new gas liquid sparger. A nearly uniform bubbles were produced. Bubble size was measured by photographic method and using software AutoCAD 2000. Bubble size of two different liquid flow rates QL= 1 and 2 (m3/h) were compared. The distribution of bubbles was normal and the majority of bubbles had a diameter of more than 2.5 millimeters, the amount of bubble between 2.5-5 mm is higher at higher liquid flow rate.

Presented Wednesday 19, 13:30 to 15:00, in session Integration of Life Sciences & Engineering - Poster (T5-P).
