DIAPHRAGM (3.3 ltr)
For the requirements of smaller bath volumes P. M. Recovery Systems has developed chrome purifier with single diaphragm which could be installed right inside the working chrome plating bath avoiding the cost of Pump/Outside tank and extra electrodes.
The working technology is electrolytic separation based on electro- dialysis using diaphragm for the removal of metallic impurities such as iron, Copper, Nickel, Aluminum, Zinc & Trivalent Chrome and also re-oxidize trivalent chrome from all types of chrome plating solutions including hard chrome and decorative chrome plating baths.
Metallic impurities such as iron, Copper, Nickel, Aluminum, Zinc & Trivalent Migrate through the diaphragm to the cathodic compartment. Cations are reduced at the cathode resulting into evolution of hydrogen raising the pH of the catholyte, this results into the metal hydroxides precipitation in the cathodic chamber.
