抄録

The rapid separation of fine silica particles (mean diameter of 200 nm) deposited from geothermal water were investigated by using a column bed packed with ferro-nickel slag wool. If repulsive double-layer interaction prevented particle adhesion on collector wool surface, collection efficiency greatly improved by modifying the slag wool surface with ferric hydroxide, aluminium hydroxide or aluminium silicate. In the experimental results, silica collection in 1 mM KNO3 electrolyte at pH 5 reached 17 % at dimensionless time 2 by Fe-Ni slag wool collector. On the other hand, silica recovery prominently increased up to 80 % by ferric hydroxide modification wool, 100 % by aluminum hydroxide modification wool and 85 % by aluminum silicate modification wool. These results were interpreted by the heterocoagulation theory, estimating surface interaction energy between silica particle and collector surface.
