The porosity and morphology properties of ceramic membrane

Abstract

The success of ceramic membranes as solute separation and filtration makes membrane technology widely used because it has high effectiveness and efficiency as a solute separator and filtration. The solute separation and filtration performances of typical ceramic membranes depend on the porosity properties of the ceramic membrane itself. Membrane porosity indicates the number of porous areas in the membrane. Precipitated silica as filler was added into the ceramic membrane at 0.30 %, 1.01 %, 1.68 %, 2.34 %, and 2.99 % per hundred masses of the membrane. It was revealed that silica acting as a membrane filler increased the porosity of the ceramic membrane. This was confirmed with the SEM (Scanning Electron Microscopy) test and Origin Software. From the test results the highest porosity value is at 2.99 % per hundred masses of membrane.
