| titleOfInvention | Water treatment method using reverse osmosis membrane |
| abstract | In a water treatment method for treating water to be treated containing silica with a reverse osmosis membrane, it is possible to suppress generation of silica scale and slime while suppressing a decrease in flux of the reverse osmosis membrane. A water treatment method using an osmotic membrane is provided. A water treatment method using a reverse osmosis membrane in which treated water containing silica is treated with a reverse osmosis membrane, wherein (1) the pH of the concentrated water in the reverse osmosis membrane is maintained at less than 6. A water collection step of passing the treated water through the reverse osmosis membrane to obtain permeated water and concentrated water; and (2) sterilization of passing the treated water through the reverse osmosis membrane by setting the pH of the treated water to 6 or more. A preparation step, (3) a sterilization step of adding oxidant to the water to be treated and passing the water to be treated through the reverse osmosis membrane, and (4) stopping the addition of the oxidant to the water to be treated, and reverse osmosis. A water treatment method using a reverse osmosis membrane, in which a water collection preparation step of passing water to be treated through a membrane is sequentially repeated.
