Treatment of Concentrated Liquid Wastes by Electrocoagulation-Electroflottation: Toward a Closer Understanding of the Technique

Abstract

Optimization of construction parameters of the crystallizer to reach the optimal dynamic mode.Choice of best apparatus satisfying the requirements from database on crystallizer producers.The system is designed open for further development.We have developed a new concept of Technical Scale Free Flow Zone Electrophoresis (TSFFZE), primarily to separate mixtures of biological substances, as there are proteins or amino acids under the impact of an electrical field. The new device operates with one small chamber dimension (1 mm) to handle negative effects caused by the electrical field. However, in contrast to previous approaches, the smallest dimension is now parallel to the electric field. The mixture to be separated enters the cell as a thin layer, which splits up into different fractions. The required residence time is small, as the distances the molecules have to travel are in the order of a millimetre, only. This, in turn, increases throughput and limits temperature rise to a few degrees, even in adiabatic operation. A straightforward scale up to increase the throughput is not performed in the small but in the two other dimensions.
