Article Synopsis
- Water treatment plays a crucial role in sustainability, with a focus on reducing wastewater volume through an osmotic process using mixed-matrix woven forward osmosis (MMWFO) membranes modified with a TiO/NaTiO (TNT) nanocomposite.
- The study characterizes the TNT nanocomposite, revealing its unique crystal structure and surface morphology, and examines how varying TNT concentrations affect membrane performance and hydrophilicity.
- Results indicate that the optimized MMWFO membrane (0.01 wt.% TNT) achieved the highest water flow and volume reduction with distilled water, outperforming other water sources like tap water, textile wastewater, and gray water in terms of permeation efficiency.
We introduced, for the first time, a membrane composed of nanostructured self-polyether sulphone (PES) filled with graphene oxide (GO) applied to photoelectrochemical (PEC) water splitting. This membrane was fabricated through the phase inversion method. A variety of characteristics analysis of GO and its composite with PES including FTIR, XRD, SEM, and optical properties was studied.

A coated woven fabric material was used to cast the membrane polymer solution.

Nanofiltration, a promising method for water treatment, has been proposed as a solution. The phase inversion technique was used for the synthesis of nanofiltration membranes of polyethersulfone embedded with graphene oxide nanoparticles and polyethersulfone embedded with titanium nanoribbons.
