Abstract
In a method for producing sodium hypochlorite, brine solution is piped from the brine tank to a first inlet in a first electrolyzer cell of an electrolyzer assembly while simultaneously piping chilled water from a chiller having a temperature range from about 10° C. to about 25° C. to the first inlet so that the brine solution combines with the chilled water. The chilled brine solution is electrolyzed in the first electrolyzer cell. The hypochlorite and brine solution resulting from electrolysis occurring in the first cell is piped to a second inlet in a second electrolyzer cell in the electrolyzer assembly while simultaneously piping chilled water from the chiller having a temperature range from about 10° C. to about 25° C. to the second inlet so that the chilled water combines with the hypochlorite and brine solution. Each cell can have more than one inlet, preferably up to 6 inlets. The chilled hypochlorite and brine solution are electrolyzed in the second cell. The process is repeated until the hypochlorite and brine solution passes through all cells of the electrolyzer assembly.
