Abstract

DE ACUERDO CON EL PRESENTE PROCEDIMIENTO SE PURIFICA AGUA DEL SUBSUELO, DE MODO QUE SE SEPARA PRIMERO LOS COMPONENTES SOLIDOS Y A CONTINUACION LOS COMPONENTES ORGANICOS DISUELTOS SE ABSORBEN EN UNA RESINA DE ABSORCION, DE MODO QUE LOS COMPUESTOS ORGANICOS ABSORBIDOS SE DESABSORBEN CON VAPOR DE AGUA Y LA RESINA DE ABSORCION SE REGENERA CON UN ACIDO Y CON UN GAS QUE CONTIENE OXIGENO. EL PROCEDIMIENTO PERMITE, TAMBIEN EN AGUAS DEL SUBSUELO FUERTEMENTE CARGADAS, LA SEPARACION DE HIDROCARBUROS AROMATICOS Y HALOGENADOS DE FORMA TAN AMPLIA, QUE EL AGUA DEL SUBSUELO PUEDE SER AÑADIDA AL AGUA SUPERFICIAL QUE FLUYE SIN NINGUNA OTRA CONDICION. EL AGUA PURIFICADA PUEDE SER UTILIZADA INCLUSO COMO AGUA DE REFRIGERACION O DESPUES DE UNA PURIFICACION BIOLOGICA POSTERIOR TAMBIEN COMO AGUA POTABLE.
