Equipment and process for solid waste minimization in chromium and heavy metal removal from groundwater |
摘要 |
A process and equipment is disclosed for minimizing sludge formation in removal of chromium and heavy metals from chromium contaminated groundwater by using sodium sulfite for oxygen removal thereby minimizing the amount of ferrous salt necessary for reduction of chromium VI to chromium III in an alkaline solution and also minimizing the amount of excess iron salt to coprecipitate as an hydroxide to effect essentially complete removal of other heavy metals.
