Effect of BMIM-chloride on physio chemical properties of nanofiber membrane for domestic wastewater treatment Kesan BMIM-klorida ke atas sifat-sifat fisio-kimia membran nanogentian untuk rawatan sisa air domestik
Water is a vital source that is essential for all living things. With increasing demand towards water consumption, wastewater treatment is necessary. Nanofiber membrane (NFM) fabricated by electrospinning is suitable to be used as a filter especially for water treatment since it has huge surface area and high permeability compared to conventional membrane. However, fouling issue has always become a threat as it reduces membrane permeability over time. Therefore, surface modification methods are being applied to NFM where membrane surface property will be improved in order to reduce fouling. In this study, nylon 6,6 NFM was fabricated and soaked in 1-butyl-3-methylimidazolium chloride (BMIM-Cl). The coating layer of BMIM-Cl will reduce the effect of fouling while increasing membrane performance. This study also compares the ionic liquid concentration to nylon 6,6 NFM with respect to its performance and rejection. Based on the results, the coated layer of BMIM-Cl increases the permeability up to >400 L/m2.h.bar while having superior rejection of chemical oxygen demand (COD) and phosphorus content over 90. Furthermore, the time taken to reach steady-state (relates to fouling effect) increased with ionic liquid concentration, signifying the increase of BMIM-chloride concentration will reduce the effect of cake formation. © 2020, Malaysian Society of Analytical Sciences.
