| titleOfInvention | Method for preparing and supplying water for water treatment |
| abstract | Even in raw water containing a transition metal such as copper and a reducing agent such as a sulfite compound such as sodium bisulfite, a catalyst reaction caused by a sulfite ion or the like can be easily and effectively suppressed. Provided are a method for preparing water treatment feed water and a method for producing fresh water capable of protecting a semipermeable membrane provided in a water treatment system from oxidative deterioration. The present invention provides a method for preparing a water treatment feedwater by adding a thiosulfate compound to raw water containing a transition metal and a sulfite compound to obtain water treatment feedwater.
