Abstract

The present invention provides processes for producing an anolyte composition comprising the following steps: (a) providing an aqueous solution comprising one or more alkaline earth or alkali metal chloride salts in a concentration of 0.2 to 25 g/l; (b) passing the solution through an anode chamber of an electrolysis cell to obtain an anolyte; (c) reducing the concentration of oxidizing agents in the anolyte. The present invention further provides processes for producing an anolyte composition comprising the following steps: (a) providing an aqueous solution comprising one or more alkaline earth or alkali metal chloride salts in a concentration of 0.2 to 25 g/l; (b) passing the solution through a first cathode chamber to obtain a catholyte; (c) passing at least part of the catholyte through a first anode chamber to obtain an anolyte having a pH between 6 and 8; (d) reducing the concentration of oxidizing agents in the anolyte.
