Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA DESNITRIFICACION DEL AGUA, ESPECIALMENTE DEL AGUA POTABLE, CON AUXILIO DE MICROORGANISMOS OXIDANTES DEL HIDROGENO. EL PROCESO SE CARACTERIZA PORQUE EL HIDROGENO SE INCORPORA AL AGUA DURANTE UNA FASE DE GASIFICACION; PORQUE EL HIDROGENO SE GENERA POR DESCOMPOSICION ELECTROLITICA DEL AGUA; PORQUE EN LA FASE DE GASIFICACION SE GENERA EN LA CORRIENTE NATURAL UNA SOBREPRESION Y COMO CONSECUENCIA DE ELLO PARTE DEL HIDROGENO INCORPORADO SE DISUELVE EN EL AGUA; Y PORQUE EL HIDROGENO DISUELTO EN EL AGUA VUELVE A SEPARARSE MAS TARDE EN EL REACTOR, DEBIDO A LA DISTENSION DEL AGUA NATURAL CON CONTENIDO DE HIDROGENO.
