​300v 100a high voltage switch mode DC electrocoagulation rectifer

 

intruduction:

 

 

At present, the method of effectively suppressing plate passivation is to replace the DC current with pulse current power supply and reduce the electrolytic polarization. The intermittent period of pulse current can cause the electrolyzed metal ions to react fully with OH- in the water to form a flocculant, and with the water out of the electrode area, thereby reducing the metal ion oxidation film probability. Substrate commutation can periodically change the direction of polarization, damage the fixed polarization region and effectively inhibit the passivation.

 

Electrocoagulation method (waste) water treatment equipment is water treatment equipment. It uses principle of electrolysis and coagulation, to make multiple physical and chemical effects towards pollution (waste) water pollutants in the redox, neutralization, condensation, air separation and other, which rapid completion of sewage (waste) water treatment. With advantages of easy maintenance, high degree of automation, automatic plate cleaning, processing efficiency and stability, small workplace, high processing speed and so on.
