ABSTRACT The printing and dyeing industry globally faces a critical challenge with wastewater generation disposal, posing significant risks to public health the environment due hazardous reactive dyes. Various physical, chemical, biological processes are used for treating this wastewater. While chemical treatments effectively address dye-related issues, proper disposal of resulting waste remains problematic. Physical struggle complex compounds, using microorganisms show promise but heavily influenced by operating conditions. Single have limitations, thus necessitating exploration hybrid techniques. Among techniques, advanced oxidation (AOPs) promising their simplicity, scalability, cost-effectiveness, further research is needed. review analyzes pollutants at each stage industry, addressing environmental impact dyes highlighting treatment methods, advantages, disadvantages. Research into techniques sustained AOPs crucial steps toward sustainable solutions in managing challenges industry.

Abstract Clean water is a necessity for all life to survive and flourish. However, natural waters are being continuously contaminated due the release of waste streams in water. Hence, it important remove pollutants from wastewater fulfill human needs. Conventional treatment methods neither efficient nor economical wastewaters that especially contain refractory toxic pollutants. This requires novel techniques like Advanced oxidation processes (AOPs), may successfully degrade persistent micropollutants more efficiently. In this study, an azo dye Acid Red 1 was removed by three AOPs, namely Photocatalytic oxidation, Ozonation Ozonation, employing heterogenous catalysts. TiO 2 used as photocatalyst, whereas Fe-Zeolite has been further added catalyst. The study revealed photocatalysis degraded only 28% red after 15 min, ozonation, degradation percentage 95% same time. combined photocatalytic ozonation process using , achieved just 9 min time reduced 5 when Fe-zeolite added. Optimization studies initial concentration, UV intensity catalyst loading were performed. Finally, rate constants Electrical Energy per Order (EEO) values determined mechanism proposed.

Textile wastewater is widely produced and its discharge without treatment contributes to environmental pollution. The adsorption process a suitable eco-friendly due low initial cost, no formation of degradation products, operation simplicity, insensitivity toxic compounds, the possibility removal from greatly diluted solutions. Orange seed (OS) powder, which lipids were removed by hexane extraction, was evaluated as bio-adsorbent remove dyes real textile wastewater. In screening step, pH more significant variable (p-value < 0.05) than dosage, temperature, stirring speed, time. Moreover, under optimized conditions (pH = 2.6, 0.58 g/L OS powder 26 °C), 95% dye Additionally, percentage reduced only 4% when volume increased 0.05 L 10 L. Then, 96% turbidity using 3 µm tubular ceramic membrane at 11. Furthermore, permeate flux through kept constant for longer observed (<11). Therefore, proposed an interesting option, fact that orange seeds are currently not valorized and, combined with process, this could prove option
