| The objective of this study is to develop a mechanistic understanding of the rejection of trace organic compounds by high-pressure membranes, based on an integrated framework of compound properties, membrane properties, and operational conditions. High-pressure membranes, encompassing reverse osmosis (RO), low-pressure RO (LPRO) and nanofiltration (NF), may provide an effective treatment barrier for represntative trace organic compounds including disinfection by-products (DBPs; e.g., tricholoacetic acid, bromoform), chlorinated solvents (e.g., tricholorethylene, carbon tetra chloride), endocrine disrupting chemicals (EDCs; e.g., 17 beta-estrodial, bisphenol-A), and pharmaceutically active compounds (PhACs; e.g., ibuprofen, carbamazepine). These compounds are being emphasized during our research, for comparison purposes, based on considerations of compound properties, occurrence, and health effects. |
