Document Type and Number:
WIPO Patent Application WO/2015/053066
Kind Code:
A1
Abstract:
The present invention provides a water treatment system capable of efficiently separating solid matter or the like from a polymer aqueous solution. The water treatment system, which is configured so as to adjust raw-water viscosity, is provided with: a water-intake unit (8) which takes in raw water including a water-soluble polymer; an agitation device (1) for agitating the raw water flowing in from the water-intake unit (8); a separation device (2) for separating solid matter from the raw water which has been agitated; viscosity measurement units (5, 6, 50) for measuring the viscosity of the raw water flowing into the agitation device (1), and the viscosity of the raw water which has been agitated; and a control unit (4) which controls, on the basis of the measured viscosities from the viscosity measurement units and a prescribed target viscosity, the amount of an additive introduced into the agitation device (1) and/or the agitation intensity of the agitation device.
