Abstract

A bioreactor integrated with an electrically driven membrane separation process (Reverse Electro-Enhanced Dialysis - REED) is under investigation as potential technology for enhancing lactic acid bioproduction. In order reveal the operation of the integrated process to achieve a specific production goal, a methodology for goal driven control system development is expanded to handle periodically operating systems. In this paper the pH control issue is addressed. A sensitivity analysis is used as criterion for the conceptual design of the control structure.

    The other input variables required to solve the model are fixed to constant values. The purpose of this step is to determine the operation at nominal values of the input variables [76]. Once the variables have been identified, disturbances of +0.5 % are performed, analogously to the other indices.

    The influence of other operational variables, such as the hydroxide concentration in the dialysate channel and imposed current density, is not currently investigated. The reason is that those inputs can be used to facilitate the pH control in the fermenter [45]. Eq. (21) estimates the energy density consumed during half period of operation.
