Claim 0:
1. An electrochemical system for synthesizing an oxidizing agent solution from fresh water and sodium chloride, the electrochemical system comprising:
a diaphragm electrolysis apparatus comprising an anode compartment, a cathode compartment, and a tubular ceramic ultrafiltration diaphragm;
a cathode circuit for a catholyte comprising a separation vessel for separating an electrolysis gas produced in the cathode compartment from the catholyte and a heat exchanger device for cooling the catholyte;
an anode circuit for an anolyte comprising a separation vessel for separating an electrolysis gas produced in the anode compartment from the anolyte and a heat exchanger device for cooling the anolyte;
a device for feeding an aqueous sodium chloride solution into the anode compartment of the diaphragm electrolysis apparatus under pressure, said device comprising a first metering pump and a vessel for dissolving the sodium chloride;
a device for stabilizing an overpressure in the anode compartment;
a filter arranged in a feed line feeding the fresh water to the device for dissolving the electrolysis gas produced in the anode compartment; and
a second metering pump for metered feed of the catholyte from the separation vessel of the cathode circuit into the stream of the fresh water upstream of the filter,
a collection vessel for an oxidizing agent solution, the oxidizing agent solution being a solution of catholyte supplied to the fresh water by the second metering pump and electrolysis gas produced in the anode compartment dissolved in the fresh water;
wherein the device for feeding the aqueous sodium chloride solution into the anode compartment further comprises a third metering pump means for metered feeding of the oxidizing agent solution from the collection vessel for the oxidizing agent solution into the vessel for dissolving the sodium chloride and a filter arranged at an outlet of the vessel for dissolving the sodium chloride and connected to an inlet of the metering pump for feeding the sodium chloride solution under pressure into the anode compartment of the electrolysis apparatus.
