More Information
Summary:An object of the invention is to provide a water treatment method and a water treatment device which, in a treatment that uses a clarifying membrane to treat water which contains an polymeric organic matter with a weight average molecular weight within a range from 100,000 to 30,000,000, can suppress deterioration in the treated water quality and suppress blocking of the clarifying membrane. The water treatment method of the invention includes a clarifying step in which the water to be treated which contains polymeric organic matter with a weight average molecular weight within a range from 100,000 to 30,000,000 is treated using a clarifying membrane, and involves adding a cation polymer with a weight average molecular weight within a range from 30,000 to 3,000,000 to the water to be treated.
