Abstract: An automated chlorine generator is provided having a power source, an electrolytic cell able to generate chlorine by the electrolysis of sodium chloride. An anode and a cathode are provided each mounted in a separate compartment with chlorine generation in the anode compartment and hydrogen generation in the cathode compartment, the compartments being in communication through an ion permeable membrane. A mixing container having a first compartment to receive hydrogen and chlorine from the cell is provided with an outlet for water in a second compartment, in communication with the first and having an inlet for water and a float valve to control the inlet. Conductivity probes are used for detecting liquid content in the anode and the cathode compartments as well as a flushing system for draining the anode and cathode compartments.
