A. Mr Kapoor,
Please follow the same process plating units use for hexavalent Cr bearing waste water, and if you wish to recover the water and maintain zero discharge status, use membranes to remove final traces of all the pollutants.

Q. How do I dispose of potassium dichromate, sulfuric acid mixture?June Lilian

A. Hi June. The answer depends on whether you are a chemistry teacher at a school, trying to dispose of a few test tubes or a beaker; or whether you are from a plating shop using this solution; or from a manufacturer of potassium dichromate chemicals.
Potassium dichromate is toxic and carcinogenic and must not only be treated properly for disposal, but this usually must be done in accordance with specific regulations depending on the industry that you are in.
