| titleOfInvention | Water treatment method and water treatment agent composition |
| abstract | A reverse osmosis membrane treatment of water to be treated containing at least one of a chlorine-based oxidizing agent and a bromine-based oxidizing agent, or containing iodide ions, to suppress deterioration of the reverse osmosis membrane and suppress slime formation. To provide a water treatment method capable of The water to be treated includes a reverse osmosis membrane treatment step for obtaining concentrated water and permeated water using a reverse osmosis membrane for the water to be treated, and the water to be treated contains at least one of a chlorine-based oxidant and a bromine-based oxidant. 1 mol or more of iodide ion is added to 1 mol of free chlorine and 1 mol of free bromine in the water to be treated, or to water containing iodide ions, At least one of a chlorine-based oxidizing agent and a bromine-based oxidizing agent is added so that the amount of free chlorine and the amount of free bromine are 1 mol or less.
