“…A few studies have been conducted to produce membranes containing chitosan in bulk size (Sami et al 2017, Zhang et al 2020, Saiful et al 2020a, 2020b, Alshahrani et al 2021, Ikram et al 2022, Zango et al 2022. To the best of knowledge, just one work has been carried out on starch/CNP bionanocomposite membranes although CNP has been found to be promising compared to chitosan in bulk size.…”

This research aims to develop relatively new membranes from starch biopolymer incorporated with different concentrations (0, 5, 10, 15, 20% w/w of solid starch) of chitosan nanoparticles (CNP) that can be used for water treatment. The membranes were fabricated using the solvent casting method while the CNP was produced using the ionic gelation method. The membranes were characterized in terms of morphology, porosity, water vapor permeability (WVP), and water contact angle. The application of the membranes to treat water was demonstrated on methylene blue solution because methylene blue is a commonly used dye in many industries. It was found that the starch/10% CNP membrane was the optimum membrane for methylene blue dye treatment because the membrane exhibits a smooth surface, high WVP (1.67 × 10-10 g/Pa h m), high porosity (59.92%), low water contact angle value (44.8°), and resulted in the highest percentage removal of methylene blue (94.0%) after the filtration. After filtration, the starch/10% CNP membrane was still in good condition without breakage. In conclusion, the starch/CNP membranes produced in this study are promising for sustainable and environmentally friendly water treatment, especially for water containing methylene blue dye. This research aligns with current thematic trends in bionanohybrid composite materials utilization, offering innovative solutions for addressing water pollution challenges.

“…There were also limited studies done on chitosan and starch biopolymers as membranes for water treatment. Saiful et al (2020a) investigated the use of chitosan/starch-based water filtration bags through forward osmosis. The membrane inside the bags was made from Dioscorea hispida-based starch extraction.…”

“…The advantages of the FO process are low-energy consumption and low concentration polarization on the membrane surface, i.e., lesser membrane fouling than RO [6][7][8]. The FO process has been successfully studied in various applications such as wastewater recovery [9,10], seawater desalination [11], power generation and food processing [5].…”

Forward osmosis (FO) technology has a broad application prospect in the field of liquid food concentration because of the complete retention of flavor components and bioactive substances. Membrane fouling is the main obstacle affecting the FO performance and concentration efficiency. This work systematically investigated the membrane fouling behavior of the FO process for fruit juice concentration elucidated by the models of resistance-in-series, xDLVO theory and FTIR analysis. The results show that the AL-FS mode was more suitable for concentrating orange juice. Increasing the cross-flow rate and pretreatment of feed solutions can effectively improve the water flux and reduce the fouling resistance. The ATR-FTIR analysis revealed that the fouling layer of orange juice was mainly composed of proteins and polysaccharides, and the pretreatment of microfiltration can greatly reduce the content of the major foulant. There was an attractive interaction between the FO membrane and orange juice foulants; by eliminating those foulants, the microfiltration pretreatment then weakened such an attractive interaction and effectively prevented the fouling layer from growing, leading to a lower process resistance and, finally, resulting in a great improvement of concentration efficiency.

“…The use of chitosan as a cross-linked agent to obtain new membranes has been reported in this Special Issue. Saiful et al [18] developed a forward osmosis (FO) membrane from a mixture of chitosan and Dioscorea hispida starch, which was cross-linked using glutaraldehyde. The cross-linked chitosan/starch membrane was revealed to have high mechanical properties with an asymmetric structure.…”
