Study of the Influence of Granite Residue in Different Compositions to Prepare Ceramic Membranes

Article Preview

Abstract:

The exploitation and processing of granite is responsible for generating large quantities of residue, mainly in the sawing step where is producing a dark color mud that is generally discharged directly in the environment without any treatment. The use of granite residue in the production of red ceramic has been widely studied and has shown promising results. The aim of this work is to verify the incorporation of granite residue in the preparation of tubular ceramic membrane in substitution of quartz. In this research it was done the characterization of the raw materials, the membrane preparation with different amount of granite residue and characterization of the membranes by scanning electron microscopy, mercury porosimetry and tangential flux measurements. The results showed that the changing in 10% of granite residue amount in the ceramic body was enough to change the morphological characteristics of the membranes.
