Abstract: An apparatus and method for venting hydrogen from an electrolytic cell. A brine solution is supplied to an electrolytic cell where hypochlorite and hydrogen gas are produced. A non-combustible gas is introduced into the electrolyzer containing the electrolytic cell and the concentration of hydrogen in the electrolyzer is reduced to a concentration below the LEL of hydrogen.

Abstract: A method for determining the amount of residual disinfectant removing agent in a process stream to which the disinfectant removing agent has been added to completely remove a disinfectant residual, comprising the steps of: (a) drawing off a sample of the process stream; (b) mixing an acidic iodate solution and an iodide solution to produce an iodine analyzing agent; (c) adding to the sample the iodine analyzing agent in an amount sufficient to react with the residual disinfectant removing agent and leave an unreacted amount of residual iodine; (d) allowing sufficient time for the iodine to react with the residual disinfectant removing agent; (e) analyzing the sample to determine the amount of residual iodine remaining in the sample, and (f) determining the amount of residual disinfectant removing agent in the sample based on the amount of iodine analyzing agent added and the amount of residual iodine remaining in the sample after reaction.
