Mech-Chem Associates, Inc. products

This technology efficiently recovers nitric acid (HNO3). hydrochloric acid (HCl), hydrofluoric acid (HF), fluoboric acid (HBF4), methanesulfonic acid (MSA), sulfuric acid (H2SO4) and mixtures of these acids, from concentrated anodizing, pickling, and plating baths which are usually discarded. The acid is returned to the process for continued use while only a dilute stream containing the metal contaminants and a small amount of acid requires any further attention.
