Usually a single impeller is used. The impeller diameter ranges between 50% and 80% of the tank diameter. The impeller is placed one impeller diameter above the bottom of the tank. The recommended retention time in the mixing tank ranges from 9 s to 2.5 min for aluminum sulfate concentrations ranging from 10 to 100 mg L − 1 [15, 69].

For optimum performance the ratio C/T should range from 0.1 to 0.3, although hydrofoils operate with C/T approximately 0.5 Impeller positioning in the tank should be considered as there are a number of ways to orient the shaft/impeller to achieve the mixing results. Number of impellers is also a consideration depending on mixing volumes.
