Findings in the Area of Membrane Science Reported from University of Kebangsaan

  2013 MAY 29 (VerticalNews) -- By a News Reporter-Staff News Editor at Technology News Focus -- Current study results on Membrane Science have been published. According to news reporting originating in Selangor, Malaysia, by VerticalNews journalists, research stated, "This paper deals with setting-up of modified fouling index (MFI) and crossflow sampler-modified fouling index (CFS-MFI) devices for prediction of fouling potential in a reverse osmosis (RO)/nanofiltration (NF) filtration system. The setting-up procedures of the laboratory-scale MFI and CFS-MFI devices operated in constant flux were described in detail."

  The news reporters obtained a quote from the research from the University of Kebangsaan, "A practical approach to test the functionality of devices was also suggested. The devices are instrumented for monitoring transmembrane pressure, crossflow velocity, and flux at a desired time interval. A series of MFIconst.flux and CFS-MFIconst.flux tests were carried out using various types of membranes and foulants to determine the functionality and consistency of the newly developed system. The results showed that the differences between MFIconst.flux and CFS-MFIconst.flux values were more significant for high polydispersed foulants (e.g., 70-100 nm colloidal silica and Aldrich humic acid) than monodispersed foulants (e.g., 22 nm particle colloidal silica). When using the polydispersed foulants, the CFS-MFIconst.flux showed a better agreement with actual RO fouling trend than the MFIconst.flux. These observations proved that with the presence of CFS cell, the CFS-MFIconst.flux is capable of simulating a more realistic RO fouling behaviour than the MFIconst.flux value (without the consideration of crossflow effect)."

  According to the news reporters, the research concluded: "The successful setting-up of the fouling prediction devices in this study would provide a useful guide for future researchers on the fouling potential of membrane."
