Fe-Ferron method was used to investigate the role of Fe(Ⅲ) speciation in the polyferric sulfate (PFS) during the process of coagulation–flocculation with surface water. The Feb components are dominant with a broad pH variation during the coagulation. The humic acid (HA) removal is found directly related to the aggregation of iron components in the water, the maximum removal of the HA occurs in the pH range from 7 to 8, the changes of zeta potential explain that charge neutralization and the compression double electric layer are the main mechanisms of coagulation at the neutral pH value. The role of adsorption and sweep by amorphous Fe(OH)3 (s) that can not be ignored in the treatment with surface water.
