Stirred Tank Reactor. A stirred tank reactor (STR) is probably the most common type of reactor found in industry. Mixing is achieved via stirring using an impeller, and aeration is done via a sparger (a pipe that pumps in air). Baffles are also used in STRs to reduce vortexing (mini whirlpools) of the fluid.
