Abstract:
1. A method of electrochemically increasing alkalinity of a detergent comprising: providing an alkali metal carbonate, bicarbonate or sesquicarbonate source to an anode chamber of an electrolytic cell, wherein said electrolytic cell comprises said anode chamber and a cathode chamber; causing the alkali metal carbonate, bicarbonate or sesquicarbonate source to undergo electrolysis, wherein said electrolysis increases hydroxide concentration in the alkali metal carbonate, bicarbonate or sesquicarbonate source; removing carbon dioxide from said alkali metal carbonate, bicarbonate or sesquicarbonate source, wherein the resulting decrease in carbon dioxide in the alkali metal carbonate, bicarbonate or sesquicarbonate source and the increase in hydroxide concentration in the alkali metal carbonate, bicarbonate or sesquicarbonate source produces increased hydroxide alkalinity in the alkali metal carbonate, bicarbonate or sesquicarbonate source; recirculating the contents of the anode chamber directly into the cathode chamber; and generating a detergent use solution having increased hydroxide alkalinity compared to the original alkali metal carbonate, bicarbonate or sesquicarbonate source provided to the electrolytic cell.
