Abstract

The integration of lactic acid fermentation and Reverse Electro-Enhanced Dialysis (REED) is investigated based upon previously developed mathematical models. A goal driven process and operation design procedure is proposed and partially investigated. The conceptual analysis of the processes integration shows the need for an additional pH controller in the fermenten A PI controller is implemented and tested. The complete control structure for the integrated system consists of this PI controller in the fermenter plus a previously developed (Prado-Rubio et al., 2010) input resetting control structure in the REED module. The integrated system design and operation is investigated through batch production of a starter culture. Substantial productivity improvements are predicted using the REED process compared to other systems. Insights are obtained for improving the integrated design and operations procedure.
