Claim 1:
2. A process for synthesizing an oxidizing agent solution from fresh water and sodium chloride using a diaphragm electrolysis apparatus comprising an anode compartment, a cathode compartment, and a tubular ceramic ultrafiltration diaphragm, the process comprising:
feeding an aqueous sodium chloride solution from a vessel for dissolving the sodium chloride into the anode compartment of the diaphragm electrolysis apparatus under pressure;
circulating an anolyte in an anode circuit comprising a separation vessel for separating an electrolysis gas produced in the anode compartment from the anolyte;
circulating a catholyte in a cathode circuit comprising a separation vessel for separating an electrolysis gas produced in the cathode compartment from the catholyte;
metered feeding of the catholyte from the separation vessel of the cathode circuit into a stream of the fresh water,
subjecting the stream of the fresh water supplied with the catholyte to a filtering process;
dissolving the electrolysis gas produced in the anode compartment with the filtered stream of the fresh water supplied with the catholyte to obtain the oxidizing agent solution;
collecting the oxidizing agent solution in a collection vessel; and
metered feeding of the oxidizing agent solution from the collection vessel into the vessel for dissolving the sodium chloride.
