“…In comparison to activated sludge, a thin-film nanofibrous composite-cellulose nanofiber membrane improved performance in filtering supernatant. A hydraulic wash was able to remove the cake layer that had accumulated on the membrane surface, potentially eliminating or reducing the expense of removing contaminants in practice [210]. Such asymmetric membranes are promising for potential uses such as industrial wastewater treatment, including in the fuel industry, where large quantities of wastewater are produced containing pollutants such as liquified solids, petroleum-organic constituents, and other oily compounds.…”

Globally, developing countries require access to safe drinking water to support human health and facilitate long-term sustainable development, in which waste management and control are critical tasks. As the most plentiful, renewable biopolymer on earth, cellulose has significant utility in the delivery of potable water for human consumption. Herein, recent developments in the application of nanoscale cellulose and cellulose derivatives for water treatment are reviewed, with reference to the properties and structure of the material. The potential application of nanocellulose as a primary component for water treatment is linked to its high aspect ratio, high surface area, and the high number of hydroxyl groups available for molecular interaction with heavy metals, dyes, oil-water separation, and other chemical impurities. The ability of superhydrophobic nanocellulose-based textiles as functional fabrics is particularly acknowledged as designed structures for advanced water treatment systems. This review covers the adsorption of heavy metals and chemical impurities like dyes, oil-water separation, as well as nanocellulose and nanostructured derivative membranes, and superhydrophobic coatings, suitable for adsorbing chemical and biological pollutants, including microorganisms.

“…Several studies have reported excellent performance of PVDF membranes reinforced with cellulose, including high flux, strong rejection, high porosity, and excellent anti-fouling properties. [20,[23][24][25][26] This is primarily attributed to the hydroxyl groups of these natural polymers, which have been shown to enhance the formation of the beta phase in PVDF. [27] As a result, the hydrophilicity of PVDF membranes also increases, significantly reducing fouling effects.…”

The development of membrane technology is rapidly advancing, such as hydrophilic PVDF membranes, which provide anti‐fouling properties to the membrane. Therefore, this research innovates the development of hydrophilic PVDF membranes by incorporating lignin‐lignosulfonate fillers from OPEFBs in situ. This study successfully prepared hybrid PVDF membranes using the phase inversion method. ATR‐FTIR, XRD, and TGA/DSC analyses confirmed that the addition of 2 % filler promoted the formation of the β‐phase in PVDF, which was more dominant than with the addition of 4 % filler, especially in the PLs2 % membrane. SEM images of the membranes showed an asymmetric structure with finger‐like and sponge‐like pores. Interactive 3D surface imaging demonstrated increased pore potential peaks when lignosulfonate was added compared to lignin. The addition of 4 % filler had a hydrophilic‐hydrophobic repelling effect, increasing the porosity and water absorption of the PL4 % and PLs4 % membranes. Phase inversion membranes were relatively hydrophilic with a water contact angle of 61°, and adding filler reduced the membrane‘s contact angle by 8°. Based on the obtained results, it can be concluded that PVDF hybrid membranes with lignin and lignosulfonate fillers have significant potential for development in membrane technology applications that require hydrophilic membranes, such as wastewater treatment and seawater desalination.
