dc.description.abstract | Measurements of contact angle, zeta potential, and pore size distribution for clean, cationic surfactant coated, and organic fouled membranes, were conducted to obtain membranes properties, from perspectives of organic fouling mitigation. Interaction between natural organic matter (NOM) and the membrane surface was investigated using contact angle measurements, with the results being attempted to be used for mitigation of NOM fouling. Several different membranes, one nanofiltration (NF; NE70), one ultrafiltration (UF; GM), and three reverse osmosis (RO: SR, BE, FRM3) membranes, were tested. With NOM fouled membranes, contact angles obtained from the sessile drop method increased compared to corresponding clean membranes. For cationic surfactant coated membranes, contact angles measured with NaCl and sea salts solutions were substantially lower than those measured with de-ionized pure water, implying the cationic surfactant modification can have a potential to reduce hydrophobic organic fouling during desalination or relatively high salts containing wastewater reclamation processes. For NOM fouled membranes, contact angle increases and the surface charge increases negatively compared to corresponding clean membranes; the membrane surface exhibits greater hydrophobicity and less negative charge, which is supported by the FTIR spectrum measurements | - |
