This study addresses the pressing concern of rising paracetamol concentrations in aquatic environments through photocatalysis, an advanced oxidation process (AOP) known for its eco-friendly and cost-effective degradation harmful pollutants. We introduce a coiled flow inverter (CFI) photoreactor utilizing Co-Ni tungstate anchored on g-C3N4 (CoNiW-gCN) as photocatalyst. The CFI's helical design enhances mixing, heat, mass transfer while enabling effective irradiation with visible LED lights. includes synthesis CoNiW-gCN using CFI examines impact concentration, configuration, catalyst dose, recycle ratio efficiency. Results show over 99% 10 ppm 36 min 1 g/L dose 7.5% 4 × setup. rate was 2.7 times faster than batch reactor, offering scalable efficient method innovative technology.
