Method for suppressing slime in separation membrane |
abstract |
In a membrane separation apparatus using feed water or washing water containing a trihalomethane precursor, there is provided a slime suppression method for a separation membrane capable of reducing the trihalomethane content in permeate while having a sufficient slime suppression effect. provide. A bromine-based oxidant or a reaction product of a bromine compound and a chlorine-based oxidant is present in feed water or washing water to a membrane separation apparatus including a separation membrane containing a trihalomethane precursor; Or a reaction product of a bromine compound and a chlorine-based oxidizing agent and a sulfamic acid compound; or a bromine-based oxidizing agent, or a reaction product of a bromine compound and a chlorine-based oxidizing agent, and a sulfamic acid compound; This is a method for suppressing the slime of the separation membrane in the presence of the reaction product.
