“…They mentioned that pesticides with higher hydrophobicity exhibited better removal in which atrazine (log Kow of 2.34) was rejected better at 99 % than dimethoate (log Kow of 0.70) which showed only 81% rejection. This finding was in line with the results from the two other studies [35], [15]. It was then explained that a pure water layer was easily formed on the highly hydrophilic surface of the membrane.…”

“…Other than the studies on NF membranes, the study by Nikbakht Fini et al [15] on FO membranes also gave similar results. The rejection of hydrophobic pesticides reduced after the membrane was heavily saturated with pesticides which were severely adsorbed onto the surface.…”

“…Unlike permeate flux, there was insignificant effect of pH on reverse salt flux in FO membranes [46]. This claim was supported by Nikbakht Fini et al [15]. On the other hand, FO membranes had shown higher rejection at high pH solution (alkali) as both phenolic compounds and FO membrane were negatively charged hence increased the electrostatic repulsion.…”

“…When the active layer faces the feed solution and the support layer faces the draw solution, the process is operated in FO mode. On the other hand, when the support layer faces the feed solution and the active layer faces the draw solution, then the process is operated in PRO mode [15].…”

This study focuses on how operating pressure, pesticide characteristics, membrane materials, feed solution and draw solution affect the performance of thin film composite membranes on pesticides removal. The membrane separation discussed in this review involve nanofiltration (NF), reverse osmosis (RO) and forward osmosis processes (FO) (i.e., FO mode and pressure retarded osmosis (PRO) mode). High pressure shows positive effects on NF and RO membranes flux performances, but it could deform PRO membranes. Hydrophobic pesticides that are larger in size, negatively charged with small dipole moments will result in higher retention. Besides, ions in the feed solution increased the rejection efficiency and permeate flux of membrane whereas pesticides concentration has a negative effect on their retention. pH of feed solution determines the zeta potential of membrane. As for the draw solution, NaCl at higher concentration is recommended. This paper is crucial to give an overview on ways to improve the removal of pesticides with various thin film composite membranes.

“…One study compared the rejection of 3 organic micropollutants by a cellulose triacetate (CTA) FO membrane to those obtained by an AQP FO membrane and found that the AQP FO membrane had a higher rejection of micropollutants and a higher water flux at the same time (Madsen et al, 2015). Two other studies demonstrated efficient rejections of pesticides by the AQP FO membranes (Engelhardt et al, 2018;Nikbakht Fini et al, 2020). However, to our knowledge, at present most of the studies about AQP FO membranes were limited to the investigation of small numbers of compounds, using non-modularized membrane samples, and the number of studies at pilot scale using wastewater are also limited.…”

The emergence of biomimetic materials developed using nature's inspiration and biological domains can drive a paradigm shift in the design and operation of future‐generation materials in separation applications. In recent years, biomimetic membranes have drawn interest of many researchers for water treatment applications. Among the biomimetic membranes, protein‐based membranes, specifically those synthesized by aquaporin, have received much attention in recent years due to their high osmotic water permeability and excellent ability to remove small molecules, thereby overcoming the trade‐off between the water flux and the contaminant's rejection. The separation efficiency and fouling properties are significantly improved by taking advantage of the strategies evolved in nature. This review provides a comprehensive overview of the state‐of‐the‐art aquaporin‐based biomimetic membranes (ABMs), mainly focusing on their synthesis, characterization, and performance as selective layer in composite membranes for reverse osmosis, nanofiltration, and forward osmosis for water desalination. Fabrication methods and characterization techniques of ABMs and their performance in water desalination are also reviewed, while the main obstacles for their successful commercial viability in wastewater treatment are provided. The applications of ABMs in various separation processes other than water desalination and their potential market are presented to inspire future researchers in this versatile area.
