Membrane cleaning is inevitable in drinking water or wastewater treatment processes to restore the membrane permeability and to minimize the costs for membrane replacement. In this study, cleaning efficiency and flux recovery by several chemical agents were investigated to find the optimal cleaning condition. Attempts to clean regenerated cellulose UF membranes fouled with humic acids were made using NaOH, NaOCl, SDS, and EDTA. Mass balances on organic foulants before and after fouling and cleaning were done to quantify the amount of foulants removed during cleaning process. SEM and SPM were applied to characterize the membrane surface during membrane cleaning. |
