Monitoring of Particulate Fouling Potential of Feed Water with Spectroscopic Measurements

Abstract: The modified fouling index (MFI) is a crucial characteristic for assessing the fouling potential of reverse osmosis (RO) feed water. Although the MFI is widely used, the estimation time required for filtration and data evaluation is still relatively long. In this study, the relationship between the MFI and instantaneous spectroscopic extinction measurements was investigated. Since both measurements show a linear correlation with particle concentration, it was assumed that a change in the MFI can be detected by… Show more

“…However, this could be easily removed with the fluid flow, suggesting it may not be a loss of functionality of the membrane itself, but rather a decrease in the CA value due to the hydrophilic characteristics of the SNPs. This is because SNPs with a size similar to the membrane pore size seem to block the pores in the membrane [31].…”
