Abstract

Procedimiento para la concentración y el secado de medios fluidos que contienen agua, en especial de concentrados de aguas residuales, en el que se provee al medio a concentrar con un aditivo, después de lo cual se evapora el líquido, caracterizado porque antes de la evaporación se provee a los medios fluidos que contienen agua con precipitados de hidróxidos, fosfatos o arseniatos, a continuación se ajusta el pH de la suspensión obtenida a un valor mayor que 7 y se concentra por evaporación esta suspensión hasta sequedad en un dispositivo secador.
