Abstract
PROCESO Y METODO DE ABLANDAMIENTO DEL AGUA DURA POR PRECIPITACION DE CARBONATO CALCICO. EL AGUA DURA PASA A SER ALCALINA, E.J. MEDIANTE LA ADICION DE HIDROXIDO DE SODIO, PONIENDOSE POSTERIORMENTE EN CONTACTO CON UNA CANTIDAD EN EXCESO DE CRISTALES DE CARBONATO DE CALCIO CUYO TAMAÑO NO EXCEDA LOS 100 MICRONES, CON LO CUAL LA PRECIPITACION OCURRE DENTRO DE UN TIEMPO CORTO DE CONTACTO DE 2-60 SEGUNDOS. EN LA SEPARACION DEL AGUA BLANDA A PARTIR DE CARBONATO CALCICO, LA MAYOR PARTE DE ESTE ULTIMO ES RECIRCULADA Y LAS CANTIDADES EN EXCESO ELIMINADAS.
