| dc.description.abstract | This study is regarding synthesizing low cost ultrafiltration (UF) membrane that can
perform well in removing dye. To simplify this study, dye has been chosen to study the
performance rather than microorganism because of the fact that membrane that able to
remove smaller particle such as Methylene Blue (7 x 16Å) indirectly was also able to
eliminate pathogenic microorganism (20nm)The problem statement that leads to this
study is the cost of commercial UF membrane which is capable to remove
microorganism in drinking water is very high causes people could not effort to purchase
it. In this study,UF membranes were developed using waste recyclable plastics;
polyvinyl chloride (PVC) and Polystyrene (PS). Polymer solution concentration
from20% to 24% for PVC and 19% to 22% for PS was formulated. N-methyl-2-
pyrrolidone (NMP)was used as solvent for both materials to prepare casting solution.
The membranes were developed using Diffusion phase inversion method.Therejections,
flux, pure water permeability, fouling analysis were carried out and further analysed the
membrane characteristics with the aid of technologies such as Fourier Transform
Infrared (FTIR), Scanning Electron Microscope (SEM) and Atomic Force Microscope
(AFM). Another membrane with mixture of 19% PS and 3% PVC were developed and
tested the effect of mixture in additional. The rejection percentage varies when type of
polymer is different. Based on the analysis, polystyrene had shown better performance
compared to PVC material. In this study, 19% PS + 3% PVC membrane had showed the
best performance in term of rejection %, flux and fouling. | en_US |
