Preparing a Novel Pressure Driven Membrane with High Performance for Seawater Desalination

Seawater desalination offers the vast potential of producing unlimited clean water. Membrane-based desalination technologies can be used to produce alternation water source. Reverse osmosis (RO) is regarded as a reliable technique for seawater desalination. Most RO membranes have a thin-film composite (TFC) structure, and the performance of the membrane is predominantly determined by the physiochemical properties of the polyamide (PA) layer. The performance and the formation mechanism of the PA layer have been intensively studied in recent years. This project aims at fabricating the TFC membrane using a support-free IP reaction, and to explore the formation mechanisms of the PA layer in the SFIP reaction system. Results show that the performance of the fabricated RO membranes is satisfactory.
