Chromic Acid Purification CrPur Page One

The CrPur from Recovery Engineering And Sales Company, Inc. uses select ion transfer technology with application specific membranes to remove cation contaminants such as iron, copper, nickel, aluminium, zinc, etc. from decorative and hard chrome plating baths, and hexavalent chrome anodizing and conversion baths.  In addition to removing cation impurities, the CrPur will also oxidize trivalent chrome to hexavalent chrome, thus completely purifying the process tank. 

Benefits of the CrPur include: tremendous savings on operational costs, with an important reduction in the potential liability associated with treatment, transportation, and disposal of a hazardous spent bath.

Using the CrPur on your chromic acid process tank reduces operating expenses by extending the bath life virtually forever, thus eliminating disposal and replacement costs.  Other advantages of maintaining a more stabile process bath with lower levels of cation impurities are: a more uniformly plated or anodized surface, fewer rejects, a shorter plating or anodizing time, plating with lower power consumption, etc.
