  • Apparatus and method for treating waste water containing ammonium salts
    Patent number: 11820690
    Abstract: In a method for treating waste water containing ammonium salts, sodium sulfate crystal is obtained by freezing crystallization, then the pH value of the waste water is adjusted to a specific range, and next sodium chloride crystal and ammonia water is obtained by evaporation. Alternatively, the pH value of the waste water is adjusted to a specific range, then sodium chloride crystal and ammonia water is obtained by evaporation, and next sodium sulfate crystal is obtained by freezing crystallization. This method can recover ammonia, sodium sulfate, and sodium chloride from the waste water.
