Abstract

The demand for advanced water treatment technologies is continuously increasing due to clean water scarcity, strict environmental regulations, growing population, and increasing discharges of industrial wastewater. Polymer-based nanofiltration (NF) membranes are of particular interest due to their low cost and high removal efficiency for multivalent salts and emerging contaminants such as pharmaceuticals, pesticides, dyes, and emulsions. Recent advances in polymer and membrane science and technology enabled the development of more efficient separation processes. However, a recognized limitation for conventional NF membranes originates from the intrinsic trade-off relationship between rejection and permeance. Moreover, the polymeric NF membranes are facing other challenges such as stable performance, aging, scalable, and sustainable fabrication processes. Much improvement has been made over the recent years to tackle these challenges by innovative materials, polymer modifications, incorporating nanomaterials in the polymer matrix, and optimizing or developing new fabrication procedures. This chapter identifies and discusses recent breakthroughs in polymer-based NF membranes that can be applied in efficient water remediation and solvent-resistant separations.
