Conventional water resources in many regions are insufficient to meet the water needs of growing populations, thus reuse is gaining acceptance as a method of water supply augmentation. Recent advancements in membrane technology have allowed for the reclamation of municipal wastewater for the production of drinking water, i.e., potable reuse. Although public perception can be a challenge, potable reuse is often the least energy-intensive method of providing additional drinking water to water stressed regions. A variety of membranes have been developed that can remove water contaminants ranging from particles and pathogens to dissolved organic compounds and salts. Typically, potable reuse treatment plants use polymeric membranes for microfiltration or ultrafiltration in conjunction with reverse osmosis and, in some cases, nanofiltration. Membrane properties, including pore size, wettability, surface charge, roughness, thermal resistance, chemical stability, permeability, thickness and mechanical strength, vary between membranes and applications. Advancements in membrane technology including new membrane materials, coatings, and manufacturing methods, as well as emerging membrane processes such as membrane bioreactors, electrodialysis, and forward osmosis have been developed to improve selectivity, energy consumption, fouling resistance, and/or capital cost. The purpose of this review is to provide a comprehensive summary of the role of polymeric membranes in the treatment of wastewater to potable water quality and highlight recent advancements in separation processes. Beyond membranes themselves, this review covers the background and history of potable reuse, and commonly used potable reuse process chains, pretreatment steps, and advanced oxidation processes. Key trends in membrane technology include novel configurations, materials and fouling prevention techniques. Challenges still facing membrane-based potable reuse applications, including chemical and biological contaminant removal, membrane fouling, and public perception, are highlighted as areas in need of further research and development.

“…They are an energy efficient, environmentally friendly and scalable separation method in comparison with conventional processes like distillation and chromatography. To achieve wider use, better membranes are needed that are capable of performing useful separations by providing selectivity between desired components while exhibiting ease of manufacturing, high flux and resistance to fouling, described as the loss of membrane permeability due to the adhesion of feed components on the membrane surface [3][4][5][6][7].…”

“…Polymer self-assembly, which allows spontaneous formation of nano-scale structures, is a promising tool for scalable manufacture of membranes with controlled pore size and sharp selectivity while maintaining high permeability [4,[20][21][22][23][24][25]. Block copolymer (BCP) selfassembly is documented to make membranes with high-density uniformly sized pores using a bottom-up approach [4,20,26], but requires tightly-controlled processing conditions.…”

“…In contrast to these methods, polymer self-assembly can lead to membranes with exceptional performance and added functionality without the need for added processing steps, oft en through processes that can directly be plugged into existing manufacturing methods 14 . With well-designed polymers, interesting and functional nanoscale structures can be achieved spontaneously, and surface chemistry of various materials can be controlled to impart desired function.…”

Membrane technologies are essential for water treatment, bioprocessing and chemical manufacturing. Stimuli-responsive membranes respond to changes in feed conditions (e.g., temperature, pH) or external stimuli (e.g., magnetic field, light) with a change in performance parameters (permeability, selectivity). This enables new functionalities such as tunable performance, self-cleaning and smart-valve behavior. Polymer self-assembly is a crucial tool for manufacturing such membranes using scalable methods, enabling easier commercialization. This review surveys approaches to impart stimuli responsive behavior to membrane filters using polymer self-assembly.
