Abstract: Systems and methods for producing chlorine dioxide in a single vessel process include a simplified control of sodium sulfate concentration, particularly for small to medium scale chlorine dioxide generators. The benefits of the described systems and methods include high chlorate efficiency, compact design and low sulfuric acid use. In some embodiments, the described systems and methods produce chlorine dioxide and separate the chlorine dioxide for use in the treatment of drinking water. The separated chlorine dioxide for use in the treatment of drinking water has no chlorate of chlorite or levels of chlorate or chlorite that are well below allowed limits. Novel compositions from which to produce chlorine dioxide include mixtures of hydrogen peroxide and a miner al acid and mixtures of an alkali metal chlorate, alkali metal salt and hydrogen peroxide are also described.
