Among the different classifications of membrane fouling, organic fouling is perhaps the most poorly understood, with relationships to (organic) colloidal fouling and biofouling. Problematical foulants have been identified as polysaccharides and proteins but these components occur in both abiotic mac

This study aims to identify the nature of organic species (soluble or colloidal) governing membrane fouling within the context of a membrane bioreactor (MBR). A knowledge of their nature and origin (excreted during treatment or associated with the influent) can help to better adapt operational condi

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

Wastewater effluent organic matter (EfOM) was isolated into different fractions including colloids, and hydrophobic (HPO) and transphilic (TPI) fractions. The EfOM isolates were characterized by different techniques, for example, size exclusion chromatography (SEC) with on-line UVA and DOC detectors
