| 摘要 |
The invention concerns a method for treating ferruginous mineral water, rich in carbon dioxide, characterised in that it consists (a) in contacting said water with a material based on manganese dioxide (MnO2) and (b) in recuperating the treated mineral water with low iron content. The invention also concerns a method whereby the material based on manganese dioxide (MnO2) is regenerated by chemical process, optionally preceded by a regeneration by mechanical process, said chemical regeneration comprising an acid regeneration step and an oxidizing regeneration step. |
