Hexavalent chromium is treated by redox reactions that convert to trivalent chromium in insoluble form. Zerovalent metals are used in the redox reactions. We have developed technology for hexavalent chromium removal from drinking water. The technology is at pilot stage and we could share it.
Off the shelf technology for domestic use would be use of RO technology; but do verify the desired drinking water limits are reached after RO treatment.
Remediation of groundwater is more complex and would involve use of PRB's or pump and treat methods.

We propose some biological in situ treatment using indigenous strain with high Chromium resistant. The strain have capability to donate electrons on the cell surface to reduce highly soluble hexavalent to insoluble trivalent Chromium in a direct redox process.

It is an interesting work. We are interested to know the size of the Electrocoagulation equipment. Is it possible to employ in large scale at the contaminated site?

Dear Mr. Lala Behari Aukla,
Please view these two websites:
We can provide a full and complete treatment of the Chrome and all other contaminations with a one pass treatment through our Electrocoagulation equipment. Very easy to operate and very easy to dewater the sludge, which should be no-leatchable for disposal or refining.
Please contact Mr. Scott Powell for futher information.
Thank You for your time and consideration of this information.
