By studying compound process of PFS, a set of techniques of compounding solid PSAFS is devised in the paper, called one-step preparation of solid PSAFS. Through the coagulating test to treat simulating turbid water, the best parameters have been obtained by applying orthogonal design: Fe/Si molar ratio , Na_2SiO_39H_2O solution polymerizing time, reacting time, reacting temperature and Al/Si molar ratio.
