“…At first the ED was mainly used for the separation and production processes based on ion exchange membranes, which mainly includes conventional electrodialysis (CED), electroelectrodialysis (EED), bipolar membrane electrodialysis (BMED or EDBM) and electrodialysis deionization (EDI), etc. There are several comprehensive reviews which summarized ED utilization in organic acid productions [131], in environmental protection [132], for sustainable development [133], in separation process [134], in bioproducts transforming [135]. During last decades of development, ED has also been used for the energy reclamation from concentration gradient that called reverse electrodialysis (RED) [136][137][138].…”

Electrodialysis related processes are effectively applied in desalination of sea and brackish water, waste water treatment, chemical process industry, and food and pharmaceutical industry. In this process, fundamental component is the ion exchange membrane (IEM), which allows the selective transport of ions. The evolvement of an IEM not only makes the process cleaner and energy-efficient but also recovers useful effluents that are now going to wastes. However ion-exchange membranes with better selectivity, less electrical resistance, good chemical, mechanical and thermal stability are appropriate for these processes. For the development of new IEMs, a lot of tactics have been applied in the last two decades. The intention of this paper is to briefly review synthetic aspects in the development of new ionexchange membranes and their applications for electrodialysis related processes.

“…Membrane processes are essential for downstream processing in biotechnology, because of their selectivity and relatively mild operational conditions [1][2][3][4][5]. The latter are very important because of the thermal and chemical sensitivity of many bioproducts (e. g. proteins) and the high cost of biomass removal and target product(s) concentration by evaporation [6,7].…”

Downstream Processing in Biotechnology

Membrane processes are of crucial importance for downstream processing in biotechnology. This is due to their selectivity and the mild operating conditions, enabling to extract target products without damages caused by overheating and chemical agents. Besides the most spread membrane processes like ultrafiltration and reverse osmosis, electrodialysis is very important for removal and extraction of electrically charged products, i. e. anions of organic acids, some antibiotics, etc. The electrodialysis process can be organized in batch or continuous mode. On the other hand, in the electro-crossflow filtration, the transport of target solutes across the membrane is guided by two main driving forces, the transmembrane pressure and the electric potential. This combination enables various possibilities for more selective and efficient downstream processing in biotechnology. This chapter provides a brief overview of recent achievements of electrodialysis in selected bioproducts separations and recovery. A special focus, including original experimental data, is then given to electro-filtration, which is a powerful tool creating new opportunities for performing separations on the basis of both electric charge and particle size differences.
