Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA LA REUTILIZACION FAVORABLE AL MEDIO AMBIENTE DE AGUA RESIDUAL ACIDA BAJO LA FORMACION DE UN MEDIO DE ABSORCION, CARACTERIZANDOSE PORQUE LOS CATIONES AL3+, FE2+/+, CA2+ Y ANIONES INORGANICOS COMO COMPONENTES PRINCIPALES QUE CONTIENE EL AGUA RESIDUAL ACIDA DE LA PRODUCCION DE BLANQUEADO SE TRANSFORMAN CON UNA SOLUCION DE AGUA DE VIDRIO ALCALINA, SE SEPARA LA PRECIPITACION OBTENIDA A PARTIR DE LA FASE ACUOSA Y EVENTUALMENTE SE PURIFICA Y SE SECA. EL MEDIO DE ABSORCION ENCUENTRA UTILIZACION EN EL BLANQUEADO DE ACEITES O EN LA ELIMINACION DE JABONES, LIPIDOS DE FOSFORO Y METALES PESADOS A PARTIR DE ACEITES, ESPECIALMENTE ACEITES COMESTIBLES.
