Modeling and System Identification of an Unconventional Bioreactor Used for Single Cell Protein Production



In this study a model for an unconventional bioreactor, a U-loop fermentor is presented and compared to experimental data from a series of pH tracer pulse experiments. A good agreement between model and data, with very little error and computation time could be achieved when numerical diffusion combined with a carefully determined variable finite volume discretization method is employed to solve the system of partial differential model equations. The approach also overcame the obstacle posed by a constraint related to a complex pressure profile. An analysis of stability, controllability and observability if the reactor model is extended… Learn More
