PROCESS FOR REDUCING THE TOTAL ORGANIC CARBON OF AQUEOUS COMPOSITIONS

摘要

Treating (A) with active chlorine at a first pH value to obtain a second aqueous composition (B), wherein at least a portion of (B) is evacuated at a second pH value lower than the first pH value to obtain a third Obtaining an aqueous composition (C), and treating at least a portion of (C) with active chlorine at a third pH value lower than the second pH value such that the total organic carbon is less than the total organic carbon of (A) 4 A process for reducing the total organic carbon of the first aqueous composition (A), comprising the step of obtaining an aqueous composition (D).
