Abstract
La presente se refiere a un método y un aparato de eliminación de sulfato, calcio y/u otros metales solubles de las aguas residuales donde NaOH y Al(OH)₃ son puestos en contacto a una temperatura de por lo menos 60ºC y la relación molar NaOH:Al(OH)₃ al menos es 1,0, para la preparación de aluminato de sodio, el agua residual es puesta en contacto con el aluminato de sodio obtenido y un primer compuesto de calcio para la preparación de una pasta aguada que contiene estringita, se realiza una separación de sólido-líquido para la pasta aguada que contiene estringita para la separación de sólidos del líquido y de esa forma se produce una primer solución. La primer solución es puesta en contacto con un agente gasificante para la neutralización de la primer solución y precipitar el calcio contenido en la primer solución como carbonato de calcio, y se lleva a cabo una separación de sólido-líquido para separar el carbonato de calcio precipitado de la primer solución con el fin de obtener agua con un contenido reducido de sulfato, calcio y/u otros metales solubles.
