The paper presents some chosen questions of the non-Newtonian properties of a liquid effect on suspending and aeration in agitated systems. Special attention throughout the study was paid to the critical agitator speed and gas hold-up in viscous power-law liquids (aqueous solutions of high-molecular carboxymethylcellulose sodium salt and polyacrylamide). The tested agitator was the standard Rushton turbine. The gas distributor had a truncated cone form.
