| 摘要 |
The invention concerns an inorganic nanofiltration membrane with a detachment threshold between 100 and 2000 daltons and comprising: a multi-channel ceramic monolith support consisting of a mixture of Al2O3 and TiO2, a microfiltration membrane separating layer, an ultrafiltration membrane separating layer, preferably consisting of ZrO2, a nanofiltration membrane separating layer, preferably consisting of ZrO2, and obtained by a sol-gel type method. This inorganic nanofiltration membrane is designed for use in the sugar industry, more particularly for treating saline effluents derived from the regeneration of ion exchanging resins used if the refining of cane sugar. |
