Water treatment is an essential yet economically crucial process that has been the subject of extensive research. Pulsed Electric Field (PEF), is a non-thermal technology, has been proven effective in microbial inactivation through irreversible electroporation, making it a promising method for water disinfection. This study presents a hybrid-powered water purification system, integrating PEF and Ultraviolet-C technologies. A Marx generator is used that generates high-voltage pulses by stepping up a low DC input to significantly higher voltage levels. The generator operates by charging multiple capacitors in parallel and discharging them in series. The system is hybrid powered, in which it combines solar and AC power for both electronic and electrical components, respectively. Key objectives such as enhanced microbial inactivation, optimal energy efficiency, and compliance with potable water standards were successfully achieved. Numerous tests were conducted for the PEF only, UV-C only, and combined PEF and UVC samples, with and without 3-Stage Filtration. Results revealed that neither of the methods can stand alone in eliminating the bacteria and achieving the potable water standard. However, combining the PEF and UV-C with 3-stage filtration achieved significant microbial reductions for pathogens like Escherichia coli (E. coli) and Heterotrophic Plate Count (HPC). Physical and chemical parameters, including color, turbidity, total dissolved solids, and pH, were consistently within acceptable limits, ensuring safe water for consumption. The study’s findings underscore the synergistic effect of integrating PEF and UV-C technologies into a cost-efficient and scalable water purification solution, addressing water security issues.
