Access to clean and reliable water has become a critical concern due the global crisis. High sulfate levels in drinking raise health concerns for humans animals can cause serious corrosion industrial systems. Sulfated waters represent major challenge on Canadian prairies, leading many cattle deaths. While reverse osmosis (RO) membranes effectively remove sulfates, they are costly high-pressure requirements. Nanofiltration (NF) present more affordable alternative, outperforming traditional methods like adsorption, desalination, ion exchange. Developing low-pressure ultrafiltration (UF) microfiltration (MF) could also reduce costs. This review explores advancements polymeric materials membrane technology enhance removal, focusing used fouling improve permeate flux. Techniques discussed include phase inversion (PI), thin-film composite (TFC), nanocomposite (TFN) membranes. The highlights recent fabrication pristine nanomaterial-enhanced membranes, acknowledging both benefits limitations. Continued innovations polymer-based expected drive further performance cost-efficiency improvements. found that studies literature dealt mainly with concentrations below 2000 mg/L, indicating need address higher future studies.

Cellulose acetate (CA) was chemically modified with p-hydrazinobenzoic acid (HBA) for the fabrication of a CA-HBA polymeric membrane. The characterized using NMR, UV-Vis, and EDX/SEM techniques. exhibited high hydrophilicity, as it included carboxylic groups well hydroxyl group CA glycosidic ring. HBA moieties increased hydrophilicity number active sites inside matrix, but they did not improve thermal stability polymer, shown by thermogravimetry (TGA). Polysulfone (PSF) blended in various compositions to produce highly effective membranes water treatment applications. fabricated (CA-HBA/PSF) (5:95) (10:90) (15:85) were found exhibit stabilities. CA-HBA/PSF 15:85 membrane highest efficiency towards removal Cu (II) ions, while 5:95 salt rejection (89%).
