Introduction: Industrial wastewater (WW) has emerged as one of the significant environmental problems posing serious concerns to aquatic and human health. Among various industries, pharmaceutical compounds have been detected in environments food supply chains; therefore, they need an economical efficient treatment process. Photocatalysis is a promising technology for addressing pollution, such microbial disinfection. Methods: In this study, novel visible light-active photocatalyst was developed using activated carbon (AC) derived from local biomass; apricot kernel shell (AKS) modified with Ag 2 O/ZnO, The synthesized phototcatalyst (AC/Ag O/ZnO) characterized by tools XRD, UV-Visible spectroscopy FTIR. Extensive experiments were performed test AC/Ag O/ZnO its multi-application potential, degradation selected organic pollutants, WW heavy metal removal, first set experiments, reactive black azo dye used model pollutant optimized operating conditions time, pH, concentration, catalyst dose. second phase, treated photocatalysis process compared photolysis (without catalyst). third experimental setup, evaluated disinfection potential against common pathogens, including Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa. Results Discussion: results demonstrated up 99% removal within 4 h under optimum operation conditions, i.e., pH 5.0, concentration 10 ppm, dosage 0.5 g/L. case WW, reduction chemical oxygen demand (COD) 1195 199 mg/L achieved, outperforming photolytic treatment, which reduced 1283.5 956 mg/L. antimicrobial activity showed bacterial inhibition, zone inhibition (ZOI) measuring 7 mm E. 12 S. aureus , P. aeruginosa . Overall, research highlights carbon-based photocatalysts critical challenges through action, contributing sustainable solutions. findings will be very advantageous developing process, evaluating upscaling serving framework field application.

Slaughterhouses generate a huge amount of highly polluted wastewater; if left untreated, this effluent could seriously threaten the environment and human health. In present study, Ag2O/Ba/TiO2 nanocomposite was synthesized using precipitation method, its efficacy investigated for remediation real slaughterhouse wastewater (SWW) under visible light. Its performance assessed inactivation bacterial strains identified in SWW degradation total organic solids, volatile fixed heavy metals. The results indicated an excellent photocatalytic nanocomposites, confirmed by 87.3% 30% 40% solids removal from SWW. zone inhibition runs 4 to 9 mm, nanocomposites have demonstrated outstanding activity range. It has been shown that synthetic can function as effective photocatalyst other waste products produced various industries worldwide.
