Abstract
Process for producing a salt comprising NaCl and/or KCl from the aqueous effluents from one or more organic peroxide production processes, said process comprising the following steps (a) ensuring the pH of the aqueous effluents to be in the range from about 1-5, (b) separating the effluents in a liquid organic layer and an aqueous layer, (c) removing the organic layer, (d) raising the pH of the aqueous layer to a value in the range from about 6-14, and (e) crystallizing the salt from the aqueous layer having a pH in the range from about 6-14.
