dc.description.abstractThe significance of developing technologies that effectively disinfect water without fostering antimicrobial resistance has been underscored within the context of Sustainable Development Goal 6 and the One Health framework. Our research proposes Photodynamic Antimicrobial Chemotherapy (PACT), which employs curcumin in conjunction with LED light, as a promising approach for water disinfection. PACT demonstrated the capability to eliminate 87% of coliform bacteria from water samples within a 30-minute, markedly exceeding the effectiveness of solar water disinfection, which achieved a mere 13% reduction of coliforms. The efficacy of PACT is negatively influenced by the elevated concentrations of chlorophyll (r = 0.21, p?<?0.05), suspended particulate matter (r = 0.38, p?<?0.05), and turbidity (r = 0.30, p?<?0.05). Overall, this study advocates for PACT as a safe, cost-effective, and environmentally sustainable method for water disinfection, particularly in low- to middle-income countries. PACT is also relevant for ensuring access to safe drinking water during extreme weather events, such as floods, for populations affected by disasters. PACT not only delivers consistent disinfection efficiency but is also comparable to antibiotics in speed and efficacy. Future enhancements, including the integration of natural photosensitizers and solar-powered light sources, may further improve the techno-economic viability of PACT, optimizing its potential for providing safe water in resource-limited settings amidst challenging environmental conditions.
