Optimization of Electrodialysis

The optimum operation of electrodialysis is the same concept as that of electrolysis using ion exchange membranes. Namely, the sum of investment and running costs decides optimal operation conditions. When production capacity by electrodialysis, Q, is expressed as [Pg.227]

Process Feeding method of solution Electrodialyzer (stage) Remarks [Pg.228]

Batch wise electrodialysis Circulation in electrodialyzer Circulation in electrodialyzers One electrodialyzer (one stage) Multi-electrodialyzers (multi-stages) Small scale Small scale [Pg.228]

Continuous electrodialysis One pass One pass Partial circulation in electrodialyzer Partial circulation in electrodialyzers One electrodialyzer (one stage) Multi-electrodialyzer (multi-stage) One electrodialyzer (one stage) Multi-electrodialyzer (multi-stage) Large scale Largest scale Small scale Small and large scale [Pg.228]

In addition to the electric power for electrodialysis or electrolysis, auxiliary power, such as pumping etc. is necessary. [Pg.229]
