Abstract:
A method for producing sodium hypochlorite comprising:(a) piping brine solution to a first inlet in a first electrolyzer cell of an electrolyzer assembly while simultaneously piping chilled water from a chiller to the first inlet so that the brine solution combines with the chilled water, and electrolyzing the chilled brine solution in the first electrolyzer cell; (b) piping the hypochlorite and brine solution resulting from the electrolysis process occurring in step (a) to a second inlet in a second electrolyzer cell in the electrolyzer assembly while simultaneously piping chilled water from the chiller to the second inlet so that the chilled water combines with the hypochlorite and brine solution, and electrolyzing the chilled hypochlorite and brine solution; (c) piping the hypochlorite and brine solution resulting from the electrolysis process of step (b) to a third inlet in a third electrolyzer cell of the electrolyzer assembly while simultaneously piping chilled water from the chiller to the third inlet so that the chilled water combines with the hypochlorite and brine solution, and electrolyzing the resulting chilled hypochlorite and brine solution; (d) repeating step (c) until the hypochlorite and brine solution passes through all inlets of all cells of the eleotrolyzer assembly.
