The growing demand for surgical cotton in the healthcare sector has led to increased production southern Tamil Nadu, generating effluents that pose environmental risks due their chemical composition. Unlike conventional textile effluents, processing wastewater is distinct its lack of colour additive, but it exhibits high oxygen (COD) and contains significant inorganic pollutants, necessitating tailored treatment strategies. Despite extensive research on wastewater, effective solutions remain underexplored. This bridges this gap by exploring a novel synergic method, algae-bacterial symbiosis combined with photocatalytic degradation real effluent, order ultimately improve removal ability contaminants. general aim was study performance three continuous reactor, biological rector coupled biological-photocatalytic (CBPCR) reactor effluent during 30 days. efficacy measured observing rates nutrient, COD, microbial growth. It concluded CBPCR system successfully removed nitrate, phosphate, ammonia, COD 90%, 87%, 75%, 93% respectively. In particular, fostered vigorous growth both microalgae bacteria, as indicated total chlorophyll concentration 20.1 ± 0.91 mg/L dry cell weight 1.81 0.09 g/L. paper shows feasibility green, sustainable strategy such fills current practice industrial treatment.
