Abstract

LA INVENCION SE REFIERE A UN PROCESO DE PURIFICACION DE LAS SOLUCIONES ACUOSAS CONTAMINADAS CON IONES DE NITRATO. ESTE PROCESO SE CARACTERIZA EN QUE CONSISTE EN PRECIPITAR NITRO-ALUMINATOS DE CALCIO HIDRATADOS, DOBLES O MIXTOS, TALES QUE, EN PARTICULAR, MONONITRO-ALUMINATO DE CALCIO HIDRATADO, POR ADICION DE AL MENOS UN AGENTE QUE APORTA EL ELEMENTO DE ALUMINIO Y DE AL MENOS UN AGENTE QUE APORTA EL ELEMENTO DE CALCIO EN LAS SOLUCIONES A TRATAR, SIENDO LA RELACION MOLAR GLOBAL DEL ELEMENTO DE ALUMINIO SOBRE NITRATO AL/NO SUB 3, SUPERIOR A 1, SIENDO LA RELACION MOLAR GLOBAL DE CALCIO SOBRE NITRATO, CA/NO SUB 3, SUPERIOR A 2, Y EN QUE LA REACCION DE PRECIPITACION SE EFECTUA BAJO AGITACION, Y DE PH BASICO, PREFERENTEMENTE SUPERIOR A 10,5. EL PROCESO SEGUN LA INVENCION SE DESTINA EN PARTICULAR AL TRATAMIENTO DE LAS AGUAS CONTAMINADAS TALES COMO LAS AGUAS RESIDUALES URBANAS Y LOS AFLUENTES DE FABRICAS Y AL TRATAMIENTO DE LOS LIQUIDOS DE ESTIERCOL.
