Abstract
Industrial wastewater contains hazardous organic pollutants such as dyes like methylene blue, rhodamine B, Acid Blue, and Remazol, which are difficult to decompose naturally, pollute water, disrupt aquatic ecosystems, and exhibit toxicity. Azo dyes such as Acid Blue can even break down into carcinogenic compounds, while Remazol forms complex compounds that are hard to degrade, underscoring the need for effective wastewater treatment technologies. This research develops a catalytic membrane reactor based on CuO@CeO₂/PET activated with peroxymonosulfate (PMS) to enhance the degradation of organic pollutants in wastewater. The membrane combines the hydrophilic properties of PET with the photocatalytic activity of CuO@CeO₂, enhanced by the addition of polyvinylpyrrolidone (PVP) and polyethylene glycol (PEG). The addition of 0.4 g PVP significantly increases hydrophilicity, evidenced by a reduction in water contact angle, making the membrane suitable for water filtration applications. Additionally, the membrane with this PVP concentration achieved a water flux of 47.4 L/m².h, demonstrating high permeability for fast-flow applications. In the photodegradation test on Acid Blue, a combination of PET membrane with 0.8 g PVP activated by PMS showed the highest degradation efficiency, reaching 97.32%. This efficiency is attributed to the synergy between CuO@CeO₂ and PMS, generating effective reactive oxygen species (ROS) for pollutant degradation. These findings indicate that the modified CuO@CeO₂/PET catalytic membrane holds significant potential for cleaner, more efficient, and sustainable wastewater treatment, providing a technological solution for reducing industrial pollution. Keywords: Organic pollutants, photocatalytic, catalytic membrane, CuO@CeO₂/PET, peroxymonosulfate (PMS), dye degradation, water treatment technology.
