The way of digester mixing: ( ). A: The digester gas is compressed and injected into the liquid through lances or diffusers. B: Mechanical mixers, usually slow speed turbines, create liquid motion inside the digester. C: A combination of above three ways. D: The liquid contents are recirculated by pumping them from one location to another.
