Training device of the principle of electrododelidae

Electrodialysis is a recently developed membrane separation technology. It is widely used in various industries of water treatment, which can be used for bitter salt water delations and industrial production water treatment. use.

During the operation of electrodium osmodility, due to the migration rate of ions in the solution neutral and in the switching membrane, the phenomenon of electromatization has a polarization under high current density, which changes the pH in the solution and generates scale on the exchange membrane. Caused a decrease in water production capacity and additional energy loss. Therefore, its extreme current density must be determined before the electrodiacreatment is operated to ensure that there are many methods for electrodialyte extreme current density. The commonly used method is the voltage -current method. This experiment is this method used.

Through experiment hopes, the following goals are achieved:

1. Familiar with the structure, functions, installation methods and operation methods of each part of the electromators;
