Process for Treating Chromate Waste Liquid |
| abstract |
The present invention relates to a method for treating chromate waste liquid containing an organic acid component. The method comprises the steps of (a) adding a chromium precipitation promoter comprising at least one of a calcium component and a magnesium component to the chromate waste, and (b) adjusting the initial pH of the chromate waste to at least 9 to remove the chromium component from the chromate waste. Precipitating and reducing the concentration of dissolved chromium component in the chromate waste solution. |
