Abstract

Procedimiento de fabricación de sulfato de aluminio y sus derivados a partir de lodos de hidróxidos de aluminio procedentes de las plantas de anodizado, consistente en el aprovechamiento del hidróxido de aluminio contenido en estos lodos, mediante el secado, molturado, cribado y posterior ataque con ácido sulfúrico, hasta obtener el sulfato de aluminio, empleado como coagulante en el tratamiento de aguas.
