Product Description

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.

Advantages Of Single Diaphragm Chrome Purifier:

  • The Single Diaphragm Chrome Purifier can be installed on one side of the cathodic bus bar or at the corner of the working bath, whichever is suitable for the operator.
  • The Unit takes very little space thus causes no hindrance to the operator.
  • No need of any circulatory pump as the Diaphragm works while dipped in the working bath.
  • The same DC Rectifier which used for the Chrome plating can be used in parallel for the punfien
  • Easy to install and operate.
  • The Single Diaphragm Chrome Purifier can be used while the plant is in operation.
  • Maintenance Expenses are almost nil

Problems Faced When The Level Of Metallic Impurities Gets Too High:

  • Rough or nodular deposit.
  • Reduction in Cathode Efficiency.
  • Deposits Dull.                                                                                   
  • Reduction in plating rate.
  • Increase of electricity consumption as higher voltage is required to get the desired amperes.
  • Reduction of Bright Range.
  • Reduction in covering Power.
  • More variation in Deposit Thickness(Dog bone effect)
  • Tendency of peeling off.
  • Increased tendency for burning.
  • PittedDeposit.
