Abstract

Procedimiento de fragmentación de las emulsiones y suspensiones, útil principalmente en la depuración de las aguas residuales industriales, caracterizándose el mencionado procedimiento porque se trata bajo agitación las emulsiones y las suspensiones a tratar, por medio de un reactivo líquido seleccionado entre el conjunto constituido por las soluciones y dispersiones acuosas que comprende: a) una sustancia adsorbente, y b) aluminio o un derivado de aluminio principalmente AlCl{sub,3}, Al{sub,2}O{sub,3}, Al(OH){sub,3}, obteniéndose el mencionado reactivo líquido a partir de agua, de los productos a) y b), y por una sustancia seleccionada entre los ácidos y las bases, de forma que los micro-cristales de derivados de aluminio queden asociados en las zonas activas de a).
