Abstract

HABITUALMENTE, ESTAS AGUAS SE TRATAN CON UN PRECIPITANTE A BASE DE HIDROXIDO CALCICO Y SOSA O LEJIA SODICA PARA FORMAR UN PRECIPITADO DE CARBONATO CALCICO QUE DESPUES SE FILTRA. EL PROCEDIMIENTO DE ESTA INVENCION SE CARACTERIZA PORQUE ANTES DE LA ADICION DEL AGENTE PRECIPITANTE EL AGUA SE SOMETE A UN TRATAMIENTO CONSISTENTE EN DESGASIFICACION A VACIO PARA ELIMINAR CO2 JUNTO CON PARTE DEL O2 Y DESPUES DEL DESENDURECIMIENTO OXIGENACION DEL AGUA PARA RESTABLECER EL CONTENIDO EN O2 NECESARIO. ESTE PROCEDIMIENTO TIENE LA VENTAJA DE QUE SE AHORRAN CANTIDADES CONSIDERABLES DE PRECIPITANTE GRACIAS AL AUMENTO DEL PH DEL AGUA PRODUCIDO COMO CONSECUENCIA DE LA REDUCCION DEL CONTENIDO DE CO2.
