The continuous growth of global population has promoted the development new aquaculture techniques for enhancing food supply. Modern approaches, such as Recirculating Aquaculture Systems (RAS), present challenges concerning elimination chemical substances and pathogens that appear because their operation. In this study, simultaneous removal amoxicillin water disinfection was evaluated using different UV-C photoassisted Advanced Oxidation Processes (AOPs). processes involved oxidants hydrogen peroxide, peracetic acid, sodium hypochlorite, potassium peroxymonosulfate, persulfate. optimization radiation oxidant dosage assessed in a batch system photoreactor simulated water. Moreover, potential these treatments, well production by-products (DBPs), phytotoxicity generation matrix interaction are also addressed. Finally, first approximation to reaction mechanism is carried out via scavenging studies. Results show 10 W/m2 optimized dosages 0.1-3.2 mM range eliminate at least 80 % 2 h Disinfection achieved 1 min treatment maintained two weeks after storage. While DBPs parameters variation were minimal. Scavenging study shows HO⦁, 1O2, SO4⦁- radicals main ones antibiotic degradation. operation conditions sets path towards scale-up process systems, with objective application real
