| Popis: | Electroflotation column is preferred in many chemicals, electrochemical and biochemical wastewater process treatment due to their simplicity in design, operation and maintenance. Indeed, it is very important to have a tool to determine and optimize the size distribution of the bubbles produced inside columns. In this context and in order to improve the performance of wastewater treatment by electroflotation process, the main objective of this study was to investigate the effect of current density and liquid phase electric conductivity on the bubble size distribution and on the bubble flow regime. For this a rectangular electroflotation column was used. The method of recording and the video image analyzing was used to determine the diameter and the rise velocity of the bubbles. |
