Two natural source waters containing natural organic matter (NOM) with different physical and chemical characteristics were dead-end filtered using five types of membranes having different material and geometric properties. In this study retained dissolved organic carbon (DOC) per unit membrane area

Measurements of the rejection of perchlorate anion (ClO4–) were performed using nanofiltration (NF) and ultrafiltration (UF) membranes. Aqueous solutions of perchlorate (at a concentration of 100 µg/L of ClO4– by “spiking” with KClO4) were fed to the membrane test apparatus. Solutions contained only
