Mathematical model for continuous process in bioreactor with substrate and biomass recycle

The results of the simulation of continuous biotechnological process in the apparatus with recycle are presented. The technological scheme includes a filter for the product. The recycle contains substrate and biomass. The dependencies of biomass and substrate concentrations and the productivity on the value of the recycle speed, the value of flow and substrate concentration in the inflow are obtained. It is shown that almost for all the values of input parameters the productivity during the process with recycle is higher than the productivity without the recycle. At constant load by substrate the flow speed is possible; in this case the substrate is completely removed and the process of synthesis takes no place.
