Enhancing textile wastewater reuse: Integrating Fenton oxidation with membrane filtration.

The textile industry produces large volumes of wastewater with complex organic pollutants, dyes, and chemicals that are challenging to treat. This study introduces an integrated approach combining Fenton oxidation and membrane filtration in a continuous flow system to improve textile wastewater treatment. The study optimized the removal efficiencies of COD, TOC, and colour by varying the dosages of Fe and HO, as well as adjusting the pH and flow rates.

Highly selective and reusable nanoadsorbent based on FeO-embedded sodium alginate-based hydrogel for cationic dye adsorption: Adsorption interpretation using multiscale modeling.

This study aims to develop a stable and efficient magnetic nanocomposite hydrogel (MNCH) for selective removal of methylene blue (MB) and crystal violet (CV). MNCHs with different FeO contents (0-9 wt%) were synthesized following graft co-polymerization method using sodium alginate, acrylamide, itaconic acid, ammonium persulfate and N,N-methylene bisacrylamide. Among them, MNCH, with 5 wt% FeO, showed highest removal efficiency (>95 %).
