titleOfInvention |
Water treatment method and water treatment device using reverse osmosis membrane |
abstract |
The invention provides a water treatment method for treating a water to be treated containing ammonia using a reverse osmosis membrane, wherein the method suppresses permeation through the reverse osmosis membrane of a fungicide that contains a chlorine-based oxidizing agent or bromine-based oxidizing agent and a sulfamic acid compound. In this water treatment method in which the water to be treated containing ammonia is treated using a reverse osmosis membrane, a fungicide containing a chlorine-based oxidizing agent or bromine-based oxidizing agent and a sulfamic acid compound is added to the water to be treated, and the reverse osmosis membrane is a neutral membrane or a cationically charged membrane. |
