Pervaporation process is currently applied for brine water desalination. This high water salt content may impacts to the environmental if it is not treated well. This paper demonstrates the performance of organo-silica membrane to produce potable water treated from brine water. Organo-silica membrane was employed by applying sol gel process for 3 hours using tetra orthosilicate (TEOS) as main precursor as well as dual catalyzed (organo catalyst/citric acid) and base (ammonia) on reflux temperature of 0 ℃. The molar ratios were 1:38:0.0007:5:003 for TEOS:EtOH:Citric Acid:H2O:NH3. The citric acid was chosen as carbon source to increase the carbon chains in the silica matrices. It was found that the water flux was increased as the feed temperature also increased from 40℃. Organo-silica membrane was tested in various artificial brine water (7.5-15 wt% NaCl) operated at 40 and 60 ℃ as feed temperatures with the water flux from 1.27 to 1.55 kg.m2.h-1with excellent salt rejection of >90%.
