Article Preview

Abstract:

Introducing the main compositions and properties of fly ash, and review extraction methods of Si,Al and Fe from fly ash, compare the molecular structure and water treatment results among polysilicate flocculants, PFS and PAM, describe preparation methods, conditions and water treatment results of the polysilicate flocculants with the extracts. At last, providing some advices on how to gain flocculants with better remarkable coagulant performance.
