Different types and different electron configuration of metal ions and ZrO2 nanocrystalline of ceramic membrane hydrophilic coating surface of hydroxyl generating surface complexes developed, certainly will change after the original of ceramic membrane surface condition and surface properties, making membrane and filter medium contact interface and the nearby ion distribution affected, so as to affect the permeability flux. Figure 4 for differential pressure 0.1 MPa next, pH value for 7, different concentrations of MgCl2 at room temperature (NaCl and 298K) when the permeation flux influence. Because Mg2 + on the membrane surface characteristics, as happened adsorption MgCl2 concentration increases, permeate flux show clear downward trend. While making + on the membrane surface characteristics, as did not occur adsorption NaCl concentration increases, penetration flux is increases slightly trend. In electrolyte solution, water molecules except in different sizes of the clusters "? |
