| description | In this research, modification on ultrafiltration (UF)
membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (FO) water treatment. Two monomers, m- Phenylenediamine (MPD) and Trimesoylchloride (TMC) with
different concentration of MPD (2.0% w/v and 1.0% w/v) were reacted with TMC (0.15% w/v) for interfacial polymerization (IP) reaction to form a thin polyamide selective layer. The polyamide FO membrane prepared was characterized by using Field Emission Scanning Electron Microscope (FESEM) and contact angle measurement. Forward osmosis
membrane performances in term of water flux (L/m2hr) and
humic acid rejection (%) were evaluated in order to obtain
the best performances of FO membrane. It has been demonstrated that the result of membrane with MPD concentration of 2.0% w/v revealed a large number of fully sponge like structure and posse a high hydrophilic properties. Moreover, experimental results clearly
demonstrated that 60s reaction time of polyamide FO membrane with MPD of 2% w/v exhibited lower water flux of
1.98L/m2.h and highest humic acid rejection (99%) when 2.5M of sodium chloride (NaCl) used as draw solution. Compared to 60s reaction time of polyamide FO membrane
prepared with MPD concentration of 1.0% w/v with the same concentration of feed and draw solution exhibit a higher water flux, 3.80L/m2 but a lower humic acid rejection with 95.4% of salt rejection was observed. It is found that the overall characterization and performances of the polyamide FO membrane is mainly due to the formation and thickness of the thin polyamide layer that plays an important role in facilitating a high water flux in forward
osmosis for humic acid removal. |
