Optimization of Aerobic Fermentation

As most renewable energy and power companies know, power consumption during aerobic fermentation is one of the major operating costs. At any given point in the process, there are many combinations of airflow and agitation that will give the required mass transfer rate. But the combined power required of the agitator plus the compressor is…
