| Summary: | Water scarcity is a global catastrophe which had become the world most recent
focus due to the limitation of fresh water sources. The idea of treating wastewater is vital
as wastewater is actually freshwater that is contaminated by pollutants where it can be
considered as an alternative source of freshwater to reduce the scarcity of water
worldwide. Pollutants which occurred from industrial and human activities had increases
the present of harmful heavy metals in wastewater, hence membrane technology is
introduced as one of the methods in treating wastewater, nevertheless, there are still
limitations to this method as it has low commercial adsorbents and lack of appropriate
adsorbents with high adsorption capacity. Hence, the incorporation of polymeric
membrane with organoclay nanocomposite is introduced as this type of membrane
enables the improvement of polymer matrices such as hydrophilicity and increases the
polymer matrix's efficacy for pollutant removal in aqueous environments. This thesis
aims to develop an organoclay-based membrane embedded via phase inversion technique
and to analyse the effect of the developed membrane on the water separation performance.
The experimentation setup for this thesis separated into three phases which includes
fabrication, characterization, and testing. In the characterization of cloisite and
membrane, several analyses is carried out using FTIR, SEM-EDX, PSA, AAS, pure water
flux, and Water uptake. The result shows that the modified membrane projected uneven
trend of pure water flux, and the rejection of lead is 7.36% for membrane with 7.5 wt%
of Cloisite-15A. |
