“…Due to the rising world population, inexorably increasing consumption, and unbalanced distribution of water resources, the water crisis has become a worldwide problem. − To solve this challenge, tremendous efforts have been devoted to exploring new types of water treatment technologies at reduced energy consumption. For the past few years, a forward osmosis (FO) process has been used as a promising energy-effective separation tool in various applications including wastewater reclamation, pharmaceutical products, liquid food concentration, and power generation. − However, the lack of proper FO membranes with desirable performance has severely impeded the further development and large-scale application of this membrane technology. , …”

A polyamide composite forward osmosis (FO) hollow fiber membrane was successfully prepared with a novel copoly(phthalazinone biphenyl ether sulfone) (PPBES) polymer. Effects of different additives including ethylene glycol methyl ether (EGME) and lithium chloride anhydrous (LiCl) in the dope solution on the morphologies and properties of PPBES support membranes and composite FO hollow fiber membranes were investigated. With the increase of EGME content in the dope solution, the water flux of PPBES support membranes and FO hollow fiber membranes decreased. When LiCl was added into the dope solution, the water flux of FO hollow fiber membranes improved significantly with the increase of LiCl content. Additionally, the FO performance of the PPBES membrane was further optimized by adding triethylamine (TEA) in the interfacial polymerization (IP) process. In comparison with other FO membranes, the novel PPBES composite FO hollow fiber membrane displayed a remarkably high water flux of 45.3 L/m 2 h and a low specific reverse salt flux of 0.15 g/L.
