Abstract: This water treatment system includes a water intake section 8 for taking in a raw water containing a water-soluble polymer; a stirring unit 1 for stirring the raw water flowing into the unit from the water intake section 8; a separating unit 2 for separating a solid from the raw water after the stirring; a viscosity measuring section (5,6,50) for measuring the viscosity of the raw water flowing in the stirring unit 1, and that of the raw water after the stirring; and a control unit 4 in which on the basis of a result measured through the viscosity measuring section and a predetermined target viscosity, a control is made about the amount of an additive to be charged into the stirring unit 1, and/or the stirring intensity of the stirring unit. Thus, the viscosity of the raw water is adjusted.
