Efficency will depend on:
Dry solids concentration (Viscosity)
Tank design (circular, rectangular).
The whole ground floor has to be equipped with a grid of diffusors, which can become quite expensive.
Anyway, mixing shallow tanks has low efficiency, no matter if you use mechanical mixers or gas mixing.
