Method of cleaning waste water from hexavalent chromium |
| abstract |
The invention relates to the field of chromium wastewater treatment, can be used in the chemical, metallurgical and engineering industries and allows the process to become cheaper while maintaining a similar degree of purification. For carrying out the process, the waste water containing chromium (IV) is treated with a sulfur chloride reducing agent. After stirring for 5-6 minutes, the precipitate formed is separated. Chromium is not detected in purified water. |
