Cascade bioprocess

The CSTR cascade is often used as a substitute for CPFR behavior, and tubular reactors themselves are rarely found in bioprocessing. Exceptions are waste water treatment in oxidation ponds, river analysis (Metcalf and Eddy, 1972), sterilization technology, and fixed-bed reactors filled with immobilized enzymes for bioconversions (Lilly and Dunnill, 1972). 

Figure 6.57. Summary diagram of work flow in the systematic development of a bioprocess of the presented integrating strategy. The diagram is based on the interaction between kinetics (Chap. 5) and transport (Chap. 3) processes, which are clarified during a kinetic analysis (Chap. 4). As a special situation, the design and utilization of new types of reactors are shown (discontinuous stirred vessel, DCSTR bubble column, BC semicontinuous stirred vessel, SCSTR recycle reactor, RR continuous stirred vessel, CSTR continuous cascade, NCSTR tower reactor, TR continuous plug flow reactor, CPFR fixed and fluidized bed reactor, FBR).
