“…Among the three BED-systems used in the experiments, BED-anion was the most efficient because lactic acid can easily permeate the membrane while other substances with molecular weight of [200 or none-charge substances such as saccharide and other positively charge compounds could not pass through, thus, remain in the feed stream (Wang et al 2006). Furthermore, NH 4 OH is a weak base which is difficult to move electrochemically than strong base such as NaOH, thus current efficiency is not high.…”

The efficiency of bipolar electrodialysis (BED) for the recovery of lactic acid from fermentation broth was evaluated. Three systems of BED (bipolar-anion, bipolar-cation and bipolar-anion-cation) at fixed voltage (20 V) were compared using a model solution of ammonium lactate (100 g l(-1)). Results showed that bipolar-anion (BED-anion) was the most beneficial in terms of lactate flux, current efficiency, energy consumption and recovery ratio. Consequently, BED-anion was used to purify lactic acid from fermentation broth which had been pre-treated with mono-polar electrodialysis (MED). The final lactic acid concentration and lactate flux obtained were 144 g l(-1) and 393 g m(-2) h(-1), respectively. Using the two-step process (MED and BED-anion) the concentration of fermentation broth was increased by 33% and the total energy consumption was 2.76 kW h kg(-1).

“…EED was applied for recovery of organic acids from cyclohexanone wastes [153], and, in configuration with two CEMs (which is in fact closer to ISED as it doesn't allow pure product) (Fig. 7), was proposed for conversion of sodium glutamate into glutamic acid [138] and sodium salicylate into salicylic acid [154] ED-M was shown to be effective in recovery of lactic [155][156][157] and iminodiacetic [158] acids. However, BMED is the most widely used membrane technique for this purpose, and some pilot and commercial industrial plants are currently under operation worldwide, mostly to recover acids from fermentation broths [18,159].…”

Abstract:The applicability of ion-exchange membranes (IEMs) in chemical synthesis was discussed based on the existing literature. At first, a brief description of properties and structures of commercially available ion-exchange membranes was provided. Then, the IEM-based synthesis methods reported in the literature were summarized, and areas of their application were discussed. The methods in question, namely: membrane electrolysis, electro-electrodialysis, electrodialysis metathesis, ionsubstitution electrodialysis and electrodialysis with bipolar membrane, were found to be applicable for a number of organic and inorganic syntheses and acid/base production or recovery processes, which can be conducted in aqueous and non-aqueous solvents. The number and the quality of the scientific reports found indicate a great potential for IEMs in chemical synthesis.

“…The microorganisms and large insoluble particles can be easily removed by microfiltration or ultrafiltration, and this is almost a mature technology. Besides the two conventional filtrations, squeezing filtration by gauze followed by centrifugal separation is an alternative pretreatment method . Criteria for EDBM application were summarized by Bailly, and the first requirement is that the total multivalent cations content in the treated fluid should be less than 1–5 ppm.…”

Bioproducts have been used as bulk chemicals for processing and producing materials, chemicals and energy. The growing environmental concerns and shrinking reserves of fossil fuel have directed the attention to the production of bioproducts from renewable resources. Integrating sustainability considerations into bioproducts development make biotechnology a dominating technology platform. As bioproducts transformation and purification often contribute most to the final cost, improvements in separation techniques are essential to achieve competitive and efficient bioprocesses. One major breakthrough in transforming bioproducts is thus expected to come from novel separation techniques. Among them, electrodialysis (ED) with ion exchange membranes (IEM) has deserved special attention due to its diversity, sophisticated functions and technological compatibility. It is considered a very competitive technology when it comes to the transformation and separation of bioproducts. This review will focus on some noteworthy issues about ED technologies in producing and transforming bioproducts. © 2014 Society of Chemical Industry
