Abstract

Resumen La presente invención se refiere al tratamiento de aguas residuales industriales, y más particularmente a las aguas residuales de una planta de fertilizantes tal como una planta de fertilizantes de nitrofosfato, orgánicos u organominerales. Los iones cloruro y otras impurezas se pueden eliminar mediante electrólisis y para controlar el pH de la cámara de cátodo, el agua residual tratada de la cámara de ánodo se direcciona a la cámara de cátodo y las aguas residuales nuevas se envían a la cámara de ánodo para la posterior electrólisis. Este es un método eficiente para controlar el pH de la cámara de cátodo y evitar que aparezcan incrustaciones blancas en el cátodo. Al reducir eficientemente la concentración de cloruro en las aguas residuales de fertilizantes, es posible recircular de forma segura las aguas residuales de vuelta a la planta de fertilizantes.
