Abstract
A process for simultaneously controlling the pH and level of target ions of a liquid composition, more particularly the use of Reverse Electro-Enhanced Dialysis (REED) for extraction of low-molecular, charged species generated in a reactor. Even more particularly, the invention relates to a process for simultaneous pH control and control of inhibitors in an ongoing fermentation or catalytical system, where the pH is controlled by at least one primary Reverse Electro-Enhanced Dialysis (REED) stack and the level of target ions by at least one secondary REED stack, where the primary REED is one of a Cation REED (CX-REED) or an Anion REED (AX-REED) and the secondary REED is the other of a CX-REED and an AX-REED.
