Especially, it was observed by EPMA that Mn was attached more seriously in inside surface of membrane than in outside surface of that. The optimal cleaning method for the removal of manganese fouling was consecutive cleaning with the mixture of 1N HCl and 1% of oxalic acid, 0.3% NaOCl, and 1N HCl showing 91% of the recovery of the fouled membrane. And also, the manganese fouling problem was solved with changing the backwash conditions such as injection point of NaOCl. |
