Abstract:
The invention relates to a process for treating an aqueous medium containing (i) phosphate and (ii) cyclohexanone and/or cyclohexanone oxime, said process comprising: feeding the aqueous medium to a stripping zone; passing steam through the aqueous medium in the stripping zone; and discharging a vapor stream from said stripping zone; wherein the joint content cyclohexanone and cyclohexanone oxime in the aqueous medium entering the stripping zone is less than 0.08 wt. %.
