The present invention provides a biocidal solution having a pH of from 5 to 7 and an available free chlorine content of from 500 to 1000ppm when produced by an electrolytic cell. Also provided is a method of producing a biocidal solution in an electrolytic cell, the method including supplying to the cell a solution with a salt concentration of 2.0 to 5.0 g/L such that the solution passes through an anode chamber at a flow rate per anode surface area of 1.25 x 103 to 2.75 x 103 L hr' m-z and applying current to the cell sufficient to produce a biocidal solution with an available free chlorine content of 500 to 1000ppm and a pH of from 5 to 7. |
