Cleaning and dewatering of heavy metal sludge |
| abstract |
(57) [Summary] [PROBLEMS] To remove an inhibitor such as chloride ion which hinders the recovery of heavy metals from heavy metal sludge, A method for increasing the sludge dewatering rate is provided. SOLUTION: When dewatering heavy metal sludge with a filter press, after press-fitting is completed, washing with water or hot water removes water-soluble impurities such as chloride ions contained in the sludge and reduces the water content in the sludge. I do. |
