For off-bottom particle suspending, high speed turbines inducing axial flow in vessels are frequently used. The objective of this paper is to compare the suspending ability of various types and geometrical configurations of high-speed impellers (i.e. impellers in accordance with industrial standards of the Czech Republic and impellers designed by Techmix Ltd.). For the identification of reaching the off-bottom suspending state, a new and objective electrochemical method was used in the experiments. This experimental method eliminates the much less precise and commonly used visual method used so far.
