Electrodialysis power supply is a specialized equipment that provides the required electric field environment for the electrodialysis process. Electrodialysis is a process that utilizes the selective permeability of ion exchange membranes to separate electrolyte ions from water under the action of a direct current electric field, thereby achieving the purpose of water desalination, concentration, refinement, or purification. Electrodialysis power sources can be divided into two types: DC power sources and pulse power sources. According to different electrodialysis methods, they can output different voltages, currents, frequencies, and waveforms.
The main functions of an electrodialysis power supply are:
Provide stable and reliable DC or AC voltage to drive ions in water to migrate to opposite polarity electrodes, achieving the removal of salt in water;
Provide constant voltage or constant current mode, adjust the output voltage or current according to water quality and treatment requirements, control the migration speed and efficiency of ions in water;
Provide functions such as soft start, phase loss protection, overcurrent protection, overvoltage protection, and overheating protection to ensure the safe operation of power supply and equipment;
Provide output commutation function to achieve regular exchange between anode and cathode, prevent polarization and scaling on the membrane surface, and extend the service life of the membrane;
L provides touch screen display and operation functions, displaying operating status, fault status, output voltage, output current and other parameters, facilitating user monitoring and control.
The main advantages of electrodialysis power supply are:
The conversion efficiency is high because the switching devices have very low losses when in the on or off state;
The space occupied is small because high-frequency operation allows transformers and filtering components to be significantly reduced;
High output stability, high control accuracy, and the ability to achieve functions such as constant voltage, constant current, and positive and negative pole commutation;
Small size, light weight, easy to install and maintain;
L has multiple protection functions, such as short circuit protection, overcurrent protection, over temperature protection, etc.
