摘要：
The invention provides a process for preparing a flocculant for water treatment, said process comprising:
aging a silica sol having a SiO 2 concentration of from 100 to 200 g/L and a viscosity of less than 6 cp to prepare a silica sol having a SiO 2 concentration of from 100 to 200 g/L and a viscosity of from 6 to 30 cp, and
mixing the aged silica sol with a water-soluble metal salt.
