“…Specifically, the characteristics of the FO membrane determine its applicability and efficiency [ 139 ]. Gonzales et al [ 140 ] introduced positively charged polyethyleneimine (PEI) to the surface of an active polyamide layer to prepare positively charged thin film composite (TFC) membranes. Then, they used 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide-mediated coupling with N -hydroxy succinimide, after grafting with PEI, to quaternize with iodomethane, forming quaternary amine groups on the TFC membrane.…”

Discharging large amounts of domestic and industrial wastewater drastically increases the reactive nitrogen content in aquatic ecosystems, which causes severe ecological stress and biodiversity loss. This paper reviews three common types of denitrification processes, including physical, chemical, and biological processes, and mainly focuses on the membrane technology for nitrogen recovery. The applicable conditions and effects of various treatment methods, as well as the advantages, disadvantages, and influencing factors of membrane technologies, are summarized. Finally, it is proposed that developing effective combinations of different treatment methods and researching new processes with high efficiency, economy, and energy savings, such as microbial fuel cells and anaerobic osmotic membrane bioreactors, are the research and development directions of wastewater treatment processes.

“…Commercial cellulose triacetate membranes, in particular, exhibit remarkable ammonium rejection, reaching 99.7% (Gonzales et al 2023). Conversely, polyamide-based membranes require modification to enhance ammonium retention (Gonzales et al 2022;Li et al 2022). However, it is essential to note that cellulose ester membranes are not inherently resistant to fouling (Li et al 2018).…”

The recovery of pure water and valuable substances from wastewater is a major challenge in the context of the circular economy, requiring advanced separation methods. However, actual membrane separation techniques such as forward osmosis are limited by membrane fouling and selectivity. Here, we synthesized composite membranes by crosslinking polyvinyl alcohol hydrogel, using both glutaraldehyde and borax as crosslinking agents, on top of cellulose ester membranes. We tested these composite membranes on model and real wastewater. Results show that the composite membranes retain ammonium effectively, maintain surface electroneutrality, and exhibit remarkable resistance to fouling by organic and biological contaminants. This is explained by the high hydrophilicity of the membrane surface after application of a hydrogel layer.

“…A TFC membrane has a unique multilayer structure comprising a bottom porous polymeric support layer and a highly cross-linked top polyamide (PA) active layer, providing high water flux, salt rejection, and mechanical durability. 21,22 The TFC membranes currently available on the market are primarily designed for RO applications. Consequently, considerable efforts have been devoted to enhancing the water flux, antifouling properties, and separation performance of TFC membranes, leading to the development of special TFC−FO membranes.…”

The polyamide (PA) active layer plays a key role in the permeation and antifouling properties of thin-film composite (TFC) membranes. In this study, we synthesized a nature-based zwitterionic thin-film nanocomposite (TFN) membrane with improved organic fouling resistance. Hydrophilic zwitterionic poly(sulfobetaine methacrylate) (PSBMA) was chemically introduced onto the surface of cellulose nanofibers (CNFs) to form CNF-g-PSBMA, which was subsequently incorporated into the PA selective layer. The cross-sectional transmission electron microscopy images and 3D atomic force microscopy surface topographies of synthesized TFC membranes showed that CNF-g-PSBMA led to the formation of a thinner and smoother PA layer. The performance of membranes was investigated in a forward osmosis (FO) filtration setup in two FO and pressure-retarded osmosis (PRO) modes. The water flux in FO and PRO modes showed an increase of 16.3 and 38 LMH, respectively, with a reverse salt flux similar to that of the pristine membrane. The modified TFN membranes revealed enhanced antifouling properties against sodium alginate and bovine serum albumin foulants up to four times compared with the unmodified TFC because of their improved hydrophilicity and smoother surface. The CNF-g-PSBMA-modified TFNs demonstrated great potential for use in FO filtration, thanks to the incorporation of nature-based green materials, which significantly enhanced the membrane performance.
