GARCIA VALDES, Jesús  e  GOMEZ CARRIL, Martha. Gel de hidróxido de aluminio: análisis comparativo  de métodos de separación sólido-líquido que se utilizan en su producción. Rev Cubana Farm [online]. 2000, vol.34, n.2, pp. 87-92. ISSN 1561-2988.

Different variants of solid-liquid separation for the obtention of aluminum hydroxide, such as sedimentation, vacuum filtration (by lots and continual), pressure filtration and centrifugation were comparatively analyzed. The advantages and disadvantages of each variant, including a technical and economic analysis, were presented. It was concluded that the use of a vacuum rotary filter meets the established requirements.
