Abstract
Abstract A chlorine generator for the production of chlorine and hydrogen, with the chlorine being used for the treatment of swimming pools, sewage treatment facilities and drinking water is provided. The generator is characterized by an ion-permeable perfluorosulfonic acid membrane separating an anode and cathode compartment. Chlorine generation is controlled by an electrical timer, a chlorine pressure sensor gauge and, in an alternative embodiment, a chlorine sensor. Chlorine and hydrogen are withdrawn from the generator through aspirators and thereafter introduced into the water to be treated.
