Abstract

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.
